Edible Periwinkle

Littorina littorea (Linnaeus 1758)

Biology

provided by Arkive
The flat periwinkle grazes on detritus and microorganisms. It also feeds on green seaweeds such as sea lettuce (Ulva lactua) and species of Enteromorpha (2). Breeding may take place throughout the year, but tends to vary depending on temperature (4). The sexes are separate (individuals are either male or female), and fertilisation occurs internally after copulation (2). Egg laying is timed to coincide with the spring tide; the eggs are laid in the sea in gelatinous capsules that usually contain around three eggs (although up to 9 eggs per capsule has been known) (4). The egg capsules float in the sea and free-swimming 'veliger' larvae hatch after a few days. After 6 weeks spent in the ocean, the larvae settle on the shore. The young periwinkles attain sexual maturity at two or three years of age and may live for up to five years (2).

Description

provided by Arkive
Periwinkles are a large family of gastropod molluscs found on the shore. The edible periwinkle is perhaps the best known species of this family, as it has been collected and eaten for centuries. After boiling, the soft body is 'winkled out' from the shell with a pin or a special 'winkle-picker' (3). This species is the largest periwinkle found in Britain. It has a dark grey or black conical shell that develops a smooth surface with age. The flattened tentacles bear obvious black bands, a feature which allows young specimens to be identified easily. Males can be distinguished during the breeding season by the presence of a penis on the right side of the body (4).

Brief Summary ( Dutch; Flemish )

provided by Ecomare
Alikruiken kun je langs de hele kust vooral op de dijken vinden. Wanneer een alikruik over een hard oppervlak kruipt laat hij slijmsporen achter. In dit slijm blijven algen plakken. Andere slakjes, bijvoorbeeld wadslakjes, maken hier gebruik van en begrazen de slijmsporen van de alikruik. Als je een alikruik oppakt, verstopt hij zich in zijn huisje. Als je er een paar tegelijk pakt en ze in je hand tegen elkaar schudt, komen ze tevoorschijn. Ze denken dan dat het hoogwater is en ze in het water terecht zijn gekomen.

Brief Summary

provided by Ecomare
Periwinkles are the pebbles of the sea. You find them along the entire coast, on breakwaters, dikes, piers, etc. When a periwinkle ventures high onto the dike on a hot summer day, it lets itself roll down the slope when it gets too hot, hoping to land in water. As it crawls over a hard surface, it leaves behind a trail of slime. All kinds of algae stick to this slime. Other snails, such as laver spire shells, graze upon these slimy trails. If you pick up a periwinkle, the snail will hide in its shell. Pick up several snails and shake them in your hands, then the snails often crawl out of their shell. They confuse the shaking with wave movement. They think that the tide has risen and it is time to look for food.

Caragolí comú ( Catalan; Valencian )

provided by wikipedia CA

El caragolí comú, (Littorina littorea), és una espècie marina de gastròpode comestible.

Closca

 src=
Closca de caragolí comú

La closca arriba a fer de 10 a 12 mm essentel límit superior de 30 mm.[1] La closca pot pesar 55 mm.

Distribució

Són originaris del nord-est de l'oceà Atlàntic, des de les costes del nord de la península Ibèrica, Irlanda, Escandinàvia i Rússia.

Expansió

Aquesta espècie ha estat introduïda a la costa de l'Atlàntic d'Amèrica del Nord de manera accidental durant el segle XIX i ara és el mol·lusc predominant des de Nova Jersey cap al nord. També s'ha trobat a la costa del Pacífic de Califòrnia a Washington. La seva presència causa danys a Nord-amèrica per la competència amb les espècis de mol·luscs natives

Hàbitat

Es troba en roques en la zona alta i mtjana entre marees. També es troba en bassiols marins i en estuaris i pot arribar a fondàries de 60 m.

Cicle vital

Les femelles del cargolí comú ponen entre 10.000 a 100.000 ous continguts en una càpsula còrnia de la que escapa la larva i es posa al fons marí. Si el clima ho permet pot alimentar-se durant tot l'any. Arriba a la maduresa amb 10 mm i pot viure entre 5 i 10 anys.

Alimentació

S'alimenta principalment d'algues però pot menjar invertebrats petits com les larves del percebe.

Ús

 src=
Restes de dinar al Magdaleniense Inferior Cantàbric (15.000 abans del present) de Altamira.

Ha servit d'aliment durant centenars d'anys. A Gran Bretanya, Irlanda i Bèlgica són molt consumits. Als Països Catalans són molt apreciats. També són considerats molt bons a les cuines africanes i asiàtiques. Tenen molta proteïna (15%) poc greix (!,4%) i poques calories.

Els caraolins poden servir d'esquer per a la pesca.

Große Strandschnecke ( German )

provided by wikipedia DE
 src=
Gehäuse von Littorina littorea

Die Große oder Gemeine Strandschnecke (Littorina littorea) ist eine häufige Meeresschnecke der Küstenzonen mit einem kegelförmigen Gehäuse und einem an ihrem Fuß verankerten Deckel. Sie wird auch als essbare Strandschnecke bezeichnet, da sie schon seit alter Zeit in den Küstenländern als Nahrung diente. Ihr Verbreitungsgebiet ist der gesamte Nordatlantik ab dem 43. Breitengrad bis zur Nord- und Ostsee. Die Gemeine Strandschnecke zählt zu der Familie Littorinidae, welche innerhalb der klassischen Systematik zu den Mittelschnecken (Mesogastropoda) der Vorderkiemer (Prosobranchia) gestellt wird. In der hier verwendeten phylogenetischen Systematik werden die Littorinidae in der Ordnung Sorbeoconcha geführt.

Merkmale

Die Strandschnecke besitzt ein 1 bis 2 cm großes kräftiges und kegelförmiges Gehäuse, dessen Färbung variabel ist. Anhand der feinen Zuwachs- und Spiralstreifen auf der Gehäuseoberfläche, lassen sich bis zu sieben Umgänge erkennen, wobei die letzte große Windung den größten Teil bildet. Im Unterschied zu der ihr verwandten Art Littorea saxatilis (Kleine Strandschnecke) zeigt die Strandschnecke einen spitzen Gehäusegipfel und ihre äußere Mündungslippe führt in einem flachen Winkel an den Gehäuserand.

Vorkommen

 src=
Gemeine Strandschnecke

Der Lebensraum der Strandschnecke umfasst Weich- und Hartböden auf den weiten Wattflächen der Gezeitenzone geschützter Küstenbereiche. Besonders häufig findet man sie jedoch in der direkten Nähe von Muschelbänken, Buhnen und Molen. Hier findet sich eine Besiedlungsdichte von bis zu mehreren hundert Individuen pro m². Diese weiden mit ihrer Raspelzunge (Radula) die Algen und Tiere ab, die sich dort angesiedelt haben. Da sie die Schalen sessiler Muscheln reinigt, ist sie für das Überleben dieser Populationen oft von großer Bedeutung.

Der Hartboden stellt den bevorzugten Lebensraum der Strandschnecke dar. Auch an Steinen oder Pfählen nahe der Hochwasserlinie kriechen die Tiere empor. Im Schlick- und Mischwatt oder in den Seegraswiesen lassen sich nur wenige Tiere finden: die Verdriftungsgefahr durch Strömung und Brandung ist hier aufgrund fehlender oder nur mangelhafter Festhaftungsmöglichkeiten zu hoch.

Anpassung an den Lebensraum

Während des periodischen Trockenfallens ihres Habitats im Rhythmus der Gezeiten sammelt sich die Strandschnecke bei ablaufendem Wasser an feuchten und sonnengeschützten Orten und zieht das Gehäuse dicht an den Untergrund. Besonders an längere Trockenperioden ist die Strandschnecke durch das Verschließen des Gehäuses gut angepasst. Bei anhaltender Trockenheit kann sie ihr Gehäuse mit einem hornigen Deckel, dem Operculum, den sie auf dem hinteren Endes ihres Fußes trägt, verschließen. In diesem Zustand kann sie drei bis vier Wochen ohne Wasserbedeckung überdauern. Durch einen winzigen Spalt der Mündung kann die Schnecke Sauerstoff aus der Luft aufnehmen. Die Aufnahme von Luft-Sauerstoff kann aufgrund einer speziellen Anpassung der Atemorgane stattfinden. Die Kiemen der Strandschnecke sind zugunsten der Wand der Kiemenhöhlen, die stark mit Blutgefäßen durchsetzt sind, reduziert. Diese Anpassung ermöglicht nicht nur den Widerstand gegen unbeständige Wetterverhältnisse, sondern sie ist somit in der Lage, ein konkurrenzloses Habitat zwischen Land und Meer zu besiedeln. Im Lebensraum über der mittleren Hochwasserlinie, wo nur noch Wellen und Spritzer für Feuchtigkeit sorgen, können andere Meeresschnecken nicht mehr und Landschnecken noch nicht überleben. In dieser Zone können ihr nur Seepocken gefährlich werden, die sich auf ihren Schalen ansiedeln. Durch einen dicken Panzer von Seepocken können die Schnecken in ihrer Bewegungsfreiheit eingeschränkt werden und absterben.

Fortbewegung

Die Strandschnecke scheidet am Vorderkörper durch zahlreiche Drüsen ein 0,5–1 cm breites Schleimband aus, auf dem sie sich kriechend fortbewegt. Zusammen mit dem Körpereindruck sind diese Bänder als Kriechspuren in weichem Sediment des Wattboden gut zu erkennen.

Ernährung und Fressfeinde

Die Strandschnecke ist ein unselektiver Weidegänger. Mit der Radula werden Diatomeen und organische Partikel auf den Hart- und Weichböden abgeweidet. Auch junge Keimlinge von Algen und die Nauplien der Seepocken werden von der Strandschnecke gefressen.

Zu den Fressfeinden gehört u. a. die Strandkrabbe. Diese gibt chemische Signale von sich, welche die Strandschnecke wiederum als Warnsignal nutzt (Chemosensorik). Befindet sich jedoch Mikroplastik in der Umgebung, wird die Fluchtreaktion der Strandschnecke vermindert oder bleibt ganz aus.[1]

Fortpflanzung

In ihrer Fortpflanzung ist die Strandschnecke noch stark an das Meer gebunden. Die Eier werden bei Springtide ins Meer entlassen. Die Larven machen alle Entwicklungsstadien im Wasser durch, bevor sie an Land gehen. Andere Littorina-Arten schlüpfen direkt aus dem Ei oder sind sogar lebendgebärend wie die Kleine Strandschnecke (Littorina saxatilis).

Common periwinkle

provided by wikipedia EN

The common periwinkle or winkle (Littorina littorea) is a species of small edible whelk or sea snail, a marine gastropod mollusc that has gills and an operculum, and is classified within the family Littorinidae, the periwinkles.[2]

This is a robust intertidal species with a dark and sometimes banded shell. It is native to the rocky shores of the northeastern, and introduced to the northwestern, Atlantic Ocean.

Description

Shell of the common periwinkle

The shell is broadly ovate, thick, and sharply pointed except when eroded.[3] The shell contains six to seven whorls with some fine threads and wrinkles. The color varies from grayish to gray-brown, often with dark spiral bands.[3] The base of the columella is white.[3] The shell lacks an umbilicus. The white outer lip is sometimes checkered with brown patches. The inside of the shell is chocolate brown.

The width of the shell ranges from 10 to 12 millimetres (0.39 to 0.47 in) at maturity,[4] with an average length of 16 to 38 millimetres (0.63 to 1.50 in).[3] Shell height can reach up to 30 to 52 millimetres (1.2 to 2.0 in),[4][5][3] The length is measured from the end of the aperture to the apex. The height is measured by placing the shell with the aperture flat on a surface and measuring vertically.[6]

Littorina littorea can be highly variable in phenotype, with several different morphs known. Its phenotypic variations may be indicative of speciation, as opposed to phenotypic plasticity. This is of particular importance to evolutionary biology, as it may represent an opportunity to observe a transitional phase in the evolution of an organism.[7]

Distribution

Common periwinkles are native to the northeastern coasts of the Atlantic Ocean, including northern Spain, France, Great Britain, Ireland, Scandinavia, Russia, and Nigeria.[8]

There have been more than 14,000 observations made available as a dataset at the Global Biodiversity Information Facility - Littorina littorea,[9] which can be explored. More distribution information can also be found at Ocean Biographic Information System - Littorina littorea.[10] The NBN Gateway - Littorina littorea has a distribution map over the UK and Ireland.[11] These datasets may overlap.

Introductions to North America

Common periwinkles were introduced to the Atlantic coast of North America, possibly by rock ballast in the mid-19th century.[12] This species is also found on the west coast of the United States, from Washington to California. The first recorded sighting in the East was in 1840 in the Gulf of St. Lawrence.[12] It is now abundant on rocky shores from New Jersey northward to Newfoundland.[8][13] In Canada, its range includes New Brunswick, Nova Scotia, Quebec, Newfoundland and Labrador.[3]

L. littorea is now the most common marine snail along the North Atlantic coast. It has changed North Atlantic intertidal ecosystems via grazing activities, altering the distribution and abundance of algae on rocky shores and converting soft-sediment habitats to hard substrates, as well as competitively displacing native species.[8][13]

Ecology

Habitat

The common periwinkle is mainly found on rocky shores in the higher and middle intertidal zone.[8] It sometimes lives in small tide pools. It may also be found in muddy habitats such as estuaries[8] and can reach depths of 180 feet (55 m).[8] When exposed to either extreme cold or heat while climbing, a periwinkle will withdraw into its shell and start rolling, which may allow it to fall to the water.[14]

Zone

Movement both horizontally and vertically in response to light and dark as well as temperatures have been observed, but over a short timespan the movement seems to be random.

Experiments seem to indicate that the snail responds to light and current, and moves accordingly.[15]

Feeding

L. littorea is an omnivorous, grazing intertidal gastropod.[13] It is primarily an algae grazer, but it will feed on small invertebrates such as barnacle larvae. It uses its radula to scrape algae from rocks and, in the salt marsh community, pick up algae from cord grass or from the biofilm that covers the surface of mud in estuaries or bays. Macroalgae that are readily consumed include Ulva lactuca and Ulva intestinalis;[16] if provided, blue mussel can also be eaten.

The radula is taenioglossate, consisting of seven teeth per row: one middle tooth, flanked on each side by one lateral and two marginal teeth. The radula is used to scrape algae and detritus.

FMIB 48521 Two rows of the radula of Littorina littorea L

Phlorotannins in the brown algae Fucus vesiculosus and Ascophyllum nodosum act as chemical defenses against L. littorea.[17]

L. littorea is oviparous, reproducing annually with internal fertilization of egg capsules that are then shed directly into the sea, leading to a planktotrophic larval development time of four to seven weeks.[13] Females lay 10,000 to 100,000 eggs contained in a corneous capsule from which pelagic larvae escape and eventually settle to the bottom.[8] This species can breed year round depending on the local climate.[8] Benson suggests that it reaches maturity at 10 mm and normally lives five to ten years.[8] while Moore suggests that maturity is reached in 18 months.[18] Some specimens have lived 20 years.

Female specimens have been observed to be ripe from February until end of May, when most are spawning. Male specimens are mainly ripe from January until the end of May and lose weight after copulation. The young seem to settle primarily from the end of May to the end of June, although other sources indicate earlier settlement.[18]

Growth rate

A study in Plymouth Sound suggests an initial growth reaching up to 14 millimetres (0.55 in) in height December the first year, and 17.4 millimetres (0.69 in) by the end of the second year. Females seem to grow more rapidly than males, and in specimens above 25 millimetres (0.98 in) in height, females seem to dominate.[18] Another study undertaken in Blackwater Estuary, Essex showed growth reaching up to 8 millimetres (0.31 in) the first winter.[19]

Parasites

The common periwinkle can act as a host for various parasites, including Renicola roscovita, Cryptocotyle lingua, Microphallus pygmaeus and Himasthla sp. More studies are needed before any conclusions regarding the effect of parasites on growth can be reached. It seems that growth rate is primarily affected on available food and time available for feeding, rather than parasites.[20]

Polydora ciliata has also been found to excavate burrows in the shell of the common periwinkle when the snail is mature (above 10 mm long). The reason why this happens only to mature snails is not yet known, but one hypothesis is that a mature snail will excrete a signal substance which attracts the P. ciliata larvae. Another hypothesis is that a mature snail has a change in the shell surface that makes it suitable for P. ciliata larvae to settle. The infection by this parasite does not seem to alter the growth and proportions of the snail shell.[21]

Mortality

A mortality rate of up to 94% per annum has been observed for the first two months, followed by up to 60% per annum for the rest of the first year:

 .. out of every 950 shells of all ages [collected] at that time, 850 are first year, and 100 are in their second or subsequent year. [22] 

Older individuals above 15 months old seem to have a mortality of only 23% per annum. Cercaria emasculans is known to be fatal to the snail, but this does not account for the observed mortality.[18]

Human use

This species appears in prehistoric shellfish middens throughout Europe, and is believed to have been an important source of food since at least 7500 B.C.E. in Scotland.[23] It is still collected in quantity in Scotland, mostly for export to the Continent and also for local consumption. The official landings figures for Scotland indicate over 2,000 tonnes of winkles are exported annually. This makes winkles the sixth most important shellfish harvested in Scotland in terms of tonnage, and seventh most important in terms of value. However, since actual harvests are probably twice reported levels, the species may actually be the fourth and sixth most important, respectively.[24]

Periwinkles are usually picked off the rocks by hand or caught in a drag from a boat. They are mostly eaten in the coastal areas of Scotland, England, Wales and Ireland, where they are commonly referred to as winkles or in some areas buckies, willicks, or wilks. In Belgium, they are called kreukels or caracoles.

They are commonly sold in paper bags near beaches in Ireland and Scotland, boiled in their local seawater, with a pin attached to the bag to enable the extraction of the soft parts from the shell.

Periwinkles are considered a delicacy in African and Asian cuisines. The meat is high in protein, omega-3 fatty acids and low in fat; according to the USDA National Nutrient Database for Standard Reference, raw snails in general are about 80% water, 15% protein, and 1.4% fat.

Periwinkles are also used as bait for catching small fish. The shell is usually crushed and the soft parts extracted and put on a hook.

In accordance with their history as an ancient food source in Atlantic Europe, they are harvested and consumed in the Azores Islands by the Portuguese people, where they are usually called búzios, the generic name for sea snails.

The record for the farthest a human has spat a winkle was 10.4 metres by Alain Jourden (France) in 2006.[25]

Supply chain

As for seafood supply chains in general, the supply chain consists of a collector, processor, distributor and finally the retailer. The true nature of the supply chain is usually more complex and opaque, with the potential for records of harvesting areas and date of catch to be falsified.

Common supply chain for periwinkles.svg

Collection

Commonly harvested in buckets by workers walking in the intertidal zone on low tide; other methods have been tried.

In Maine, the snails are commonly collected by a dredge towed from a vessel.

In Norway, snorkeling has also been used.

A report on the state of the periwinkle industry in Ireland suggests a maximum catch size in order to preserve the population.

Processor

The processor buys in bulk from the collector, involving a possibly long transport route by land in a refrigerator truck or airplane, taking care to avoid temperatures below 0° Celsius.

If fresh seawater is readily available, the periwinkles are first graded if possible, using a machine custom built for the purpose. The method used for grading differs, but two proven methods include a Trommel screen with horizontal bars instead of a mesh, and a circle-throw vibrating machine also using bars. The price to purchase a complete sorting machine can be €10,000 or more.

Periwinkles are graded by number of snails per kilogram. The following table displays some common grades in France. The actual value depends upon supply and demand, with seasonal variations. The actual ranges may also differ from each establishment.

After grading, the periwinkles are "climbed" close to the consumer, which involves checking whether they are still alive. This can take anywhere from a few hours to several days, depending on how healthy the periwinkles are and the temperature of the water they climb in. Any periwinkles left immobile at the bottom are considered dead and are discarded. It is not uncommon to have up to 8% waste in a shipment.

Hereafter, the winkles are commonly packed in smaller quantities before being distributed to customers. Mesh bags from 3 to 10 kg are common.

Distributor

To sell large quantities, distributors are commonly used to move the periwinkles to the retailer. These have networks of transport available both internationally, regionally and locally inside a city. Several distributors are usually involved in the complete journal, each focusing on its own part of the transport network.

Retail

The common periwinkle is sold by fishmongers at seafood markets in large cities around the world, and is also commonly found in seafood restaurants as an appetizer or as a part of a seafood platter. In some countries, pubs may serve periwinkles as a snack.

Most of the volume fished, is consumed by France, Belgium, Spain and the Netherlands.

Methods to increase commercial value

Ongrowing has been investigated as a potential way of increasing commercial value, but no documented pilot facilities have been established. By harvesting the periwinkle during the summer and storing them with feed until December, not only should the grade have been increased, but the market value should be higher since supply is lower in the cold winter months.[26]

Aquaculture

Raising the common periwinkle has not been a focus due to its abundance in nature and relatively low price; however, there are potential benefits from aquaculture of this species, including a more controlled environment, easier harvesting, less damages from predators, as well as saving the natural population from commercial harvesting.

Packaging

Commonly packed in 3 kg boxes by the processor, the box is usually polystyrene foam or thin wood, depending on the market demands. Holes in the box ensures that any water lost by the snails drains out, so that they remain in better condition for longer. A label indicates the fishing zone, packaging date, and any other information required by law.

Storing

In a fridge, the common periwinkle can usually be stored for up to a week, but this may vary depending on how long they have been stored prior to sale, and how they have been kept since the moment they are fished. As long as they are kept moist and cold, they can survive well for a longer period of time. It is not recommended to store at temperatures below 0 degrees Celsius, even if research has shown a Median Lower Lethal Temperature of -13.0 degree Celsius.[27] Even if the common periwinkle survives when put back into seawater, they seem to be unable to move and climb.

Rantakotilo ( Finnish )

provided by wikipedia FI

Rantakotilo eli litorinakotilo (Littorina littorea) on rantakotiloiden heimoon (Littorinidae) kuuluva pieni etukiduskotilo, joka elää Pohjois-Atlantin rantavyöhykkeessä.[2][3]

Ulkonäkö

Rantakotilolla on luja kuori, joka on enintään 3,2 cm korkea ja 2,5 cm leveä. Kuoressa on viisi tai kuusi pulleaa kierrettä, joiden välissä on vain ohut sauma. Kierteiden muodostama spiraali on ulkoneva ja teräväkärkinen varsinkin nuorilla kotiloilla. Ylimmät kierteet ovat joskus täysin litteät tai jopa koverat, ja alin kierre voi olla peräti 85 % koko kotilon korkeudesta. Kuori näyttää sileälle vanhoilla kotiloilla, mutta siinä on lukemattomia kasvurenkaita ja hentoja, spiraalin suuntaisia harjanteita.[2]

Kuori on tavallisesti musta tai harmaanruskea, mutta joskus myös punainen, oranssi tai valkoinen. Väri on tummempi kierteiden välissä ja vaaleampi spiraalin kärjessä. Kuoren suuaukko on korvanmuotoinen ja kotilo voi halutessaan peittää sen kalkkikannella. Suuaukon tumma ulkoreuna saa alkunsa viimeisestä kierteestä ja paksu sisäreuna valkoisen keskuspylvään eli columellan tyvestä. Tuntosarvet ovat litteät ja leveät, ja niissä on mustia juovia.[2]

Levinneisyys

Rantakotilon alkuperäinen levinneisyysalue on Euroopassa ja ulottuu Pohjois-Espanjaan etelässä ja Vienanmerelle pohjoisessa. Sitä tavataan yleisesti Britteinsaarten, Alankomaiden ja Helgolandin rannikolla. Sen sijaan Englannin kanaalin ja Scillynsaarilla se on harvinainen.[2]

Laji on levinnyt Euroopasta ihmisen mukana Pohjois-Amerikan itärannikolle jo ennen 1800-luvun puoltaväliä. Nykyisin sitä tavataan paikoin myös Pohjois-Amerikan Tyynenmeren rannikolla.[3]

Litorinameri

Suolapitoisuus rajoittaa rantakotilon levinneisyyttä, eikä se tämän takia menesty nykyisessä Itämeressä. Itämeren varhaisvaiheista Litorinameren aikaan (noin 7000-4000 vuotta sitten) suolapitoisuus oli nykyistä korkeampi, ja tuon ajan kerrostumissa ranta- l. litorinakotilon kuoret ovat yleisiä Itämeren sisäosissakin. Näistä kuorista merivaihe on saanut nimensä.

Elintavat

Rantakotilot sietävät hyvin murtovettä ja viihtyvät kaikenlaisilla rannoilla suojattomia kalliorantoja lukuun ottamatta. Ne elävät yleensä vuorovesivyöhykkeessä, mutta levinneisyysalueen pohjoisosissa myös sen alapuolella 60 metrin syvyyteen saakka. Suojaisissa oloissa ne saattavat lähteä vaeltamaan liejuisille rannoille ravinnon perässä.[2]

Kalastus ja käyttö

Rantakotiloita kerätään ihmisravinnoksi keskimäärin 2 000–3 000 tonnia vuodessa pääasiassa Irlannissa.[4]

Littorina littorea ( French )

provided by wikipedia FR

Bigorneau

Littorina littorea, plus connue sous le nom de Bigorneau (bigorneau vrai), est une espèce de mollusques gastéropodes marins à coquille spiralée du genre Littorina.

Dénominations

Le bigorneau vrai est aussi connu sous les dénominations francophones suivantes : bigorneau commun, bigorneau gris, bourgot, littorine, vignot (sur le littoral de la Manche), guignette (sur le littoral compris entre la Loire et la Gironde) et bigorneau anglais (au Canada où il a été introduit) ainsi que bigorne, brigaud, farin et berlingaou en Bretagne ... En anglais il se nomme Periwinkle.

Description

Le bigorneau a le corps mou et une coquille en spirale, conique et pointue. Il rampe sur son pied en broutant des bouts d'algues, en particulier d'algues vertes comme des ulves, dont la laitue de mer (Ulva lactuca). Le bigorneau est un gastéropode rugueux au toucher dont la couleur est variable. À 5 ans il peut mesurer 27 mm.

Alimentation

C'est un brouteur herbivore, il se nourrit d'algues vertes (ulves et entéromorphes) et de diatomées. Il se déplace en rampant sur son pied[1].

Reproduction

Cette espèce est gonochorique (mâle et femelle séparés). La maturité sexuelle est atteinte après environ 2 ans (taille de 12 à 14 mm). En période de reproduction (toute l'année mais principalement au printemps) les individus tendent à migrer vers le haut de l'estran pour former des rassemblements parfois denses (jusqu'à plusieurs centaines d'individus par m²)[2]. Après accouplement et fécondation interne, la femelle libère dans l'eau des groupes de 5 mm. Ces capsules flottent et se dispersent durant environ une semaine puis après un stade planctonique (6 mm à ce stade)[2].

Croissance

Le bigorneau mesure environ 5 mm à un mois, de 16 mm à un an et demi et 22 mm en moyenne à deux ans et demi et 27 mm à cinq ans. Une femelle adulte de plus de 24 mm pondra jusqu’à dix fois plus d’œufs qu’une jeune femelle tout juste mature de 14 mm[2].

Utilisation

  • Des restes de repas attestent de leur utilisation dès le Magdalénien inférieur cantabrique (15 000 ans Avant le Présent) dans la grotte d'Altamira en Espagne.
  • Les bigorneaux sont consommés cuits, souvent à l'apéritif. Ils sont retirés de leur coquille à l'aide d'une épingle. Les cuire dans une eau salée et éventuellement abondamment poivrée. Le bigorneau, avec le buccin, est sans doute la source la plus importante de magnésium parmi les aliments courants (400 mg/100 g).

Habitat et répartition

C'est une espèce littorale, même si on la retrouve parfois jusqu'à 60 m de profondeur. Ce mollusque vit sur toutes les côtes européennes et nord-atlantiques tempérées : Méditerranée, Atlantique, Manche et mer du Nord, Atlantique Nord-Ouest.

Caramuxo ( Galician )

provided by wikipedia gl Galician

O caramuxo, caramuxa, caramecha, mincha ou bígaro (Littorina littorea, Linnaeus 1767) é un molusco gasterópodo mariño, de pequeno tamaño, que vive nas zonas rochosas da costa. Pertence á familia dos litorínidos (Littorinidae), da orde dos Sorbeoconcha.

Morfoloxía

Presenta a cuncha cónica, en espiral e ápice en punta, alcanzando tamaños máximos de 2,5 cm de altura. A cor é habitualmente escura (parda a negra), mostrando bandas concéntricas claras e escuras. Na superficie vense numerosas estrías espirais.

A abertura da cuncha é ovoide e o opérculo, de natureza córnea, pecha esa abertura durante a baixamar.

O caramuxo ten dous tentáculos longos e os ollos na base deles. O pé é forte.

Hábitat e bioloxía

Vive sobre as pedras e algas da franza intermareal, distribuíndose no Atlántico e Mediterráneo.

Aliméntase, como as lapas, das algas que colonizan as pedras.

Aproveitamento pesqueiro e comercial

É un molusco comestible e bastante apreciado.

Existen outras especies semellantes, algunhas comestibles e outras non.

O caramuxo en Galicia

Outros nomes populares deste molusco son os de cornecho (común a outros gasterópodos de cuncha en espiral), cuco, meiga; en Malpica chámano mexacán [3].

Segundo Eladio Rodríguez dunha muller pequena de corpo dise que é unha mincha.

Sarmiento contaba o seguinte:

Los mariscos caramujos se venden en Pontevedra muy baratos, y los chicos los compran a trueque de zoquetes de pan. Véndense cocidos y para comerlos se saca con un alfiler la poca comida que tienen pues no es la décima parte de la que tiene un caracol de tierra.

Fjörudoppa ( Icelandic )

provided by wikipedia IS

Fjörudoppa (fræðiheiti: Littorina littorea) er sæsnigill af Fjörudoppuætt.

Útbreiðsla

Fjörudoppa er algeng við strendur Norður-Atlantshafs og útbreidd í Evrópu, frá Hvítahafi í norðri til suðurstrandar Portúgals. Hennar hefur jafnvel verið getið á Svalbarða, en þó hefur ekki fengist staðfest að hún lifi svo norðarlega nú á dögum. Hún er algeng við flestar breskar og danskar strendur og nær inn í EystrasaltBorgundarhólmi. Sunnar er hún algeng við Bretagneskaga og suður til Oléron-eyju en syðstu mörk hennar virðast vera við Algarve í Portúgal.

Í Vestur-Atlantshafi er fjörudoppan dreifð allt frá Belle-eyju við Nýfundnaland til Virginíufylks í suðri. Strönd Connecticut virðist vera syðsta hentuga búsvæði hennar, en þó kemur fyrir að straumar flytji lirfur lengra til suðurs, allt að New Jersey og Delmarvaskaga þar sem dýrið hefur stundum sest að. Syðst hefur tegundin náð í Norður-Ameríku til Wachapreague í Virginíuríki.

Fjörudoppan lifir einkum á föstum og stöðugum botni í flestum fjörugerðum nema helst mjög opinni klettaströnd. Venjulega heldur fjörudoppan sig á steinum eða klettum milli há- og lágflæðimarka innan um þörunga. Einnig lifir hún á leirbotni og í einstaka tilvikum á sandbotni þar sem er traust festa. Fjörudoppan lifir allt niður á 60 metra dýpi við norðurströnd Bretlands og í Skagerrak.

Skelin (kuðungurinn)

Littorina littorea 02.JPG

Fjörudoppan verður fullorðin yfirleitt á milli 16 til 38 mm á hæð og 10 til 12 mm á breidd, allt eftir lífsskilyrðum á hverjum stað. Hafa þó fundist 52 mm á hæð. Kuðungurinn er traustur, ýmist grár eða grábrúnn og oft með dökkum þverröndum. Munninn skástæður, nær hann því sléttskaraður upp á næsta vinding, hvítur á lit en útröndin oft með brúnum flekkjum. Vindingar 6-7, grunnvindingurinn sínu stærstur, miðlungs kúptir, saumurinn grunnur. Með lágri keilulaga hyrnu og yddum hvirfli.

Almennt

Fjörudoppan þolir allháan hita, en þó meiri í lofti en sjó. Fjörudoppan fellur í dá við 32 °C lofthita og 31 °C sjávarhita. Hitadauði varð við 42 °C lofthita og 40 °C sjávarhita hjá eintökum úr Firth of Forth í Skotlandi. Ef hitastig fellur niður fyrir 8 °C leggjast flest dýrin í dvala og eyða hluta af vetrinum án þess að nærast.

Fjörudoppa finnst oft við ármynni og stundum halda dýrin inn í firði og upp í árósa þar sem seltan er aðeins um 9-10%. Hún lifir mest á kísilþörungum, þörungagróum og gróðurleifum, en einstaka sinnum á dýraleifum. Kvendýrið gýtur um það bil 500 sviflægum eggjum er klekjast út á 5-6 dögum. Lirfan er einnig sviflæg og er sviftíminn oftast 4-5 vikur. Dýrið virðist geta náð allt að 20 ára aldri. Fjörudoppa er sumstaðar talið mikið góðgæti, rétt eins og beitukóngur eða ígulker.

Littorina littorea ( Italian )

provided by wikipedia IT

La littorina comune (Littorina littorea (Linnaeus, 1758)) è un mollusco gasteropode della famiglia Littorinidae.[1]

Descrizione

 src=
Conchiglia di littorina comune

Le conchiglie, sia di individui maschi che di femmine, alla maturità hanno una dimensione da 10 a 12 mm, con un limite massimo di 30 mm[2], mentre l'altezza della conchiglia può raggiungere i 55 mm.

Biologia

Comportamento

Come quasi tutte le lumache, le littorine strisciano usando il piede muscoloso, che viene lubrificato da una pellicola di muco. Quando non è attiva, spesso si rifugia in una fessura o cavità. Durante la bassa marea quando è esposta all'aria, essa può sigillare l'apertura tra la sua conchiglia e la roccia con il muco onde prevenirne l'essiccazione. Quando è slegata dal substrato essa può effettivamente sigillare la sua conchiglia sia contro l'essiccamento che contro i predatori usando il suo opercolo.

Riproduzione

Le femmine depositano 10.000-100.000 uova contenute in una capsula cornea da cui le larve fuoriescono e si sistemano sul fondo. Essa può generare tutto l'anno secondo il clima, pervenendo a maturazione a 10 mm e vivendo 5–10 anni.

Alimentazione

Principalmente si nutre d'alghe, ma anche di piccoli invertebrati come le larve di cirripedia. Le littorine pascolano lungo la superficie sulla quale esse vivono, ed usano la loro radula per raschiare le alghe dalle rocce, e, nella comunità dell'acquitrino salato, raccoglie alghe dalle spartine (cord-grass)[3] o dalla pellicola che copre la superficie del fango negli estuari o baie.

Distribuzione e habitat

 src=
Un ammasso di littorine comuni nell'isola di Sylt, Germania

La distribuzione nativa di queste specie è nel nord-est dell'Oceano Atlantico: costa della Spagna settentrionale, Irlanda fino a Scandinavia e Russia.

La littorina comune viene principalmente trovata sulle coste rocciose nella più alta e media zona intercotidale. Talvolta vive in piccole pozze di marea nella roccia create dal ritiro dell'alta marea. È stata anche trovata in ambienti fangosi come gli estuari, situati nella battigia, al limite estremo dell'alta marea e può raggiungere anche la profondità di 60 m.

Introduzioni

Rappresenta una specie aliena sulle rive nord-occidentali dell'Oceano Atlantico del Canada e Stati Uniti e sembra possa essere stata introdotta con le rocce di zavorra verso la metà del Ottocento.[4]

Venne trovata per prima nel Nord America nel 1840 nel Golfo di San Lorenzo meridionale (Canada).[4] ed è attualmente un mollusco predominante dal New Jersey in su, verso nord.

Negli U.S.A. viene trovata nelle zone costiere, sulla costa orientale (dal Maine alla Virginia) e sulla costa occidentale (dalla California a Washington). Ebbe inoltre un grande impatto negativo sugli ecosistemi invasi, poiché entrò in competizione con i gasteropodi nativi.

Usi alimentari

Per centinaia di anni le littorine comuni o edibili sono state raccolte sulle rive dalla gente per cibarsi. Di solito esse sono staccate dalle rocce a mano o catturate con una "rete a strascico" di pescatore dalla barca. Esse si mangiano nel Regno Unito e in Irlanda dove sono comunemente chiamate "winkles" (o in alcune aree "willicks" o "wilks"). Non è raro trovare littorine cotte vendute in sacchetti di carta sulle spiagge irlandesi, di solito condite con sale, con uno stecchino attaccato al sacchetto per agevolare l'estrazione del mollusco dalla conchiglia.

In Belgio, dove anche vengono mangiate, esse vengono riferite come "crickles". In Francia, si chiamano "Bigorneau" e sono presenti cotti su tutti i piatti di frutti di mare.

Le littorine sono una prelibatezza nella cucina africana ed asiatica.

La carne ha un alto contenuto in proteine, ma basso in percentuale di grassi; secondo l'USDA (database delle sostanze nutrienti nazionali per la consulazione ordinaria), le lumache crude in genere hanno circa l'80% d'acqua, il 15% di proteine e 1.4% di grassi.

Le littorine possono anche essere usate come esca per prendere piccoli pesci. La conchiglia di solito viene frantumata e la morbida littorina così estratta si infilza in un amo.

Alikruik ( Dutch; Flemish )

provided by wikipedia NL

De alikruik (Littorina littorea) is een in zee levende kieuwslak. In de provincie Zeeland, waar de alikruik in Nederland het meest wordt gevonden, verzameld en gegeten, noemt men deze slak ook wel kreukel (ook in Vlaanderen gangbaar), karakol, alikruuk, alekreukel of krukel.

Beschrijving

Schelpkenmerken

Deze soort heeft een zeer stevige afgerond kegelvormige schelp met een spitse top. De hoogte van de schelp is gelijk aan of groter dan de breedte. Er zijn 6 tot 7 bolle windingen met een oppervlaktesculptuur van horizontale spiraalribben. De schelp is meestal bruingrijs met evenwijdig aan de ribben verlopende donkere en lichtere kleurbanden. De mondrand en het callus is wit. Er is een dun bruin hoornachtig operculum met een spiraalvormige opbouw.

De schelphoogte is tot 40 mm, echter meestal kleiner (ongeveer tot 24 mm). De breedte van de schelp is tot 35 mm, echter meestal kleiner (ongeveer tot 22 mm).

Voortplanting

Bij de voortplanting worden de eitjes in kleine doorzichtige eikapsels afgezet waaruit na enkele dagen de larven kruipen. In tegenstelling tot op het land levende slakken kennen de larven een extra vrijzwemmend stadium (veligerlarve) waarbij ze totaal niet op de volwassen dieren lijken. De veligerlarven zweven in het zeewater en behoren in deze periode tot het zoöplankton. Na enkele weken wordt de larvale schelp te zwaar voor een zwevend bestaan en zinkt de larve naar de bodem. Alleen als ze in een geschikte omgeving terechtkomen groeien ze tot volwassen dieren uit.

Habitat en levenswijze

De soort leeft in en vlak onder de getijdenzone op vaste ondergrond zoals rotsen, stenen en algenmatten, maar ook wel op houten palen, strandhoofden en andere objecten. Het is een zeer sterke soort in meerdere opzichten. Zo kan de slak zeer lage zoutgehalten en vervuiling overleven, ook raakt een door de golven losgeraakte slak maar zelden beschadigd vanwege het zeer stevige huisje. De slak zet zich vast op objecten met behulp van een slijmlaagje waardoor de zeestroming en de golven het dier niet meeneemt. Bij laag water, als de slak niet meer in het water zit, wordt het huisje afgesloten met het operculum zodat het dier niet uitdroogt. Het voedsel bestaat uit algen en zeewier maar ook dode materialen worden gegeten.

Areaal

De slak is algemeen verspreid in het Noordzeegebied.

Fossiel voorkomen

De soort wordt in Nederland vrij algemeen, soms zelfs zeer talrijk gevonden in de Formatie van Maassluis die dateert uit het (Tiglien en Pretiglien). Het is een kenmerkende soort van de Zone van Mya arenaria en Hydrobia ulvae. In België en Engeland is de soort ook iets ouder bekend. Daar komt zij al in het Boven Plioceen voor. Dat is te verklaren uit het feit dat in Nederland schelphoudende ondiep mariene afzettingen uit deze periode ontbreken. In jongere afzettingen is deze soort bekend uit alle interglacialen waaruit mariene lagen in het Noordzeegebied bekend zijn.

Oorsprong

De oudste vertegenwoordigers van het geslacht Littorina zijn bekend uit het gebied van de Grote Oceaan. De oudste vertegenwoordigers in de Atlantische Oceaan zijn echter pas bekend uit het Plioceen. Men neemt aan dat ergens in het Plioceen vertegenwoordigers van deze groep via de Beringstraat van de Pacifische naar de Atlantische Oceaan zijn gemigreerd. Dit wordt voor veel soorten mollusken aangenomen. Andere vertegenwoordigers uit deze migratiegolf zijn de uitgestorven Acila cobboldiae en de nog recent voorkomende strandgaper, het nonnetje, de wulk en de purperslak.

Consumptie van alikruiken

De alikruik geldt in veel landen als delicatesse. De slak wordt gekookt, eventueel met kruiden (peper), en met een (kromme) naald of grote speld uit het huisje gehaald, nadat het zgn. "hoedje" er met de naald is afgehaald. Schelp en hoedje worden weggegooid. De smaak is te vergelijken met kippenvlees, maar is toch zo apart, dat veel mensen het niet lusten, maar dat komt dan toch meestal wel doordat het de vorm en uiterlijk van een slak heeft. Niet iedereen is gecharmeerd van kreukels.

Vanlig strandsnegl ( Norwegian )

provided by wikipedia NO
Littorina littorea 02.JPG

Vanlig strandsnegl, stor strandsnegl eller kattsnegl, er et bløtdyr og tilhører sneglene i gruppen strandsnegler. Denne marine sneglen lever under tidevannssonen på berg og klipper og er vanlig langs hele norskekysten.

Utseende

Vanlig strandsnegl er den største av strandsneglene i Norge og kan bli 4 cm lang. Larvestadier frittlevende (pelagisk) i vann og de ånder med gjeller.

Vanlig strandsnegl og spiss strandsnegl er ganske like, men kan skilles fra hverandre på formen på åpningen i sneglehuset, det vil si leppenes vinkel i forhold til spiret. Spiss strandsnegl finnes helst i den øvrerste halvdelen av fjæra, mens vanlig strandsnegl foretrekker den nedre halvdelen.

Levevis

Vanlig strandsnegl lever på 0-70 meters dyp, på steinbunn, vanligvis under tidevannsonen. Ikke på sandbunn. Den tåler ikke en lengre periode i luft, uten å tørke ut. Den har ikke utviklet lunge, slik som noen andre strandsnegler.

Mat

Vanlig strandsnegl er regnet som snacks i flere land, blant annet i England og Frankrike.

Pobrzeżka pospolita ( Polish )

provided by wikipedia POL

Pobrzeżka pospolita (Littorina littorea) – gatunek średniej wielkości morskiego ślimaka z rodziny Littorinidae. Występuje pospolicie w litoralu i strefie pływów w północnym Atlantyku.

Etymologia nazwy

Nazwa rodzaju pochodzi od siedliska, w którym gatunek występuje (litoralis łac. – nadbrzeżny)[3]).

Cechy morfologiczne

 src=
Muszla pobrzeżki pospolitej (Littorina littorea).
 src=
Muszla pobrzeżki pospolitej (Granville, Normandia).

Wielkość muszli: długość 20-53 mm. Skrętów 6-7. Krawędź wargi zewnętrznej ostra. Muszla grubościenna, kulisto-stożkowa z wyraźnym, słabo zaznaczonym szwem i niską umiarkowanie wysklepioną skrętką. Gładka zewnętrzna powierzchnia muszli z delikatnymi, spiralnymi prążkami. Linie przyrostowe słabo widoczne. Na tle oliwkowo-brązowej powierzchni przebiegają niezbyt wyraźne, ciemnobrązowe lub purpurowobrązowe pasy. W niektórych populacjach muszle ciemnobrunatne, pomarańczowe, czerwone lub szare. Bez dołka osiowego. Wewnętrzna strona muszli z brązowawymi plamami. Ubarwienie, kształt i wielkość muszli wykazuje dużą międzyosobniczą zmienność[1][4].

Występowanie

Pierwotny zasięg obejmował północno-wschodnie wybrzeża Atlantyku (od północnej Hiszpanii do Rosji). W Bałtyku tylko w zachodniej, silniej zasolonej części. Zawleczony na wschodnie wybrzeże Ameryki, znajdowany również na zachodnim, pacyficznym wybrzeżu (m. in. w Kalifornii)[1][5][6].

Biologia i ekologia

Zajmowane siedliska

 src=
Grupa pobrzeżek pospolitych na kamieniu podczas odpływu (Sylt, Niemcy).

Żyją w litoralu, w strefie pływów, zajmują też jeziorka pływowe. Spotykane głównie na wybrzeżu skalistym lub kamienistym, mniej obficie na równiach pływowych, estuariach. Wytrzymują okresowe, zmniejszone zasolenie wody, pozostają aktywne również w czasie odpływu, gdy są wynurzone, o ile tylko przybój zapewnia zraszanie wodą[7][8].

Odżywianie

Roślinożercy, zdrapywacze, rozdrabniacze – żywią się trawami morskimi, glonami, peryfitonem[1]. Preferowane gatunki: Ulva lacuca i Enteromorpha intestinalis[9].

Rozmnażanie

Rozdzielnopłciowe, jajorodne. Jaja w galaretowatych kapsułach jajowych uwalniane wprost do wody, w trakcie przypływu. W pojedynczej kapsule zwykle 3-9 jaj. Rozwój złożony, z larwą swobodnie pływającą. Larwa osiedla się po ok. 6 tygodniach rozwoju[10]. Dojrzałość płciową młodociane osobniki osiągają po ok. 2-3 latach2. Długość życia – do pięciu lat 2[10][11].

Interakcje międzygatunkowe

Pobrzeżki są jednym z ważniejszych roślinożerców w strefie pływów, kontrolującym wzrost peryfitonu i glonów[12]. Pobrzeżki stanowią ważne źródło pokarmu dla organizmów z wyższych poziomów troficznych (np. drapieżnych ślimaków Polinices sp., Nassarius sp. Urosalpix cinerea), krabów i raków pustelników (Pagurus ssp.), rozgwiazd) oraz ptaków i ssaków związanych z morzem.

Ciekawostki

  • pobrzeżki pospolite są ważnym źródłem pożywienia dla ludzi. W Irlandii i Wielkiej Brytanii stanowią szósty, pod względem wielkości połowów, gatunek „owoców morza”, generujący przychody na poziomie 5 mln funtów rocznie[10].
  • brunatnice, które wchodzą w skład diety pobrzeżki, w siedliskach, w których są zagrożone przez żerujące ślimaki, aby je odstraszyć produkują toksyczne polifenole[13].
  • jedno ze stadiów rozwoju Morza Bałtyckiego nosi nazwę Morza Litorynowego od nazwy naukowej pobrzeżki pospolitej (Littorina littorea), która w tym czasie (ok. 4-5 tys. lat temu) była tam jednym z dominujących gatunków.

Littorina littorea ( Portuguese )

provided by wikipedia PT

Littorina littorea (denominada, em inglês, common periwinkle[4][5][6] ou common winkle[4][7], shore periwinkle[8], edible winkle ou edible periwinkle[4][9]; em português, caramujo, borrelho, burgau, burrié[4][10] ou caracol-marinho (POR)[11]; em castelhano, caracolillo ou bígaro común; em alemão, Uferschnecke, gemeine Uferschnecke, gemeine Strandschnecke, Hölker[4][12]; em francês, bigorneau, bigorneau commun, littorine commun, littorine commune d'Europe, vignot e caracole[4][13]; em gaélico escocês, faocha; em italiano, littorina comune[4][14]; em sueco, vanlig strandsnäcka; em catalão, caragolí comú; em dinamarquês, store strandsnegl ou almindelige strandsnegl; em neerlandês, gewone alikruik ou alikruik; em finlandês, rantakotilo; em norueguês bokmål, storstrandsnegl; em norueguês nynorsk, storstrandsnigel)[4] é uma espécie de molusco gastrópode marinho-litorâneo do norte do oceano Atlântico, pertencente à família Littorinidae; sendo classificada por Carolus Linnaeus em 1758, como Turbo littoreus, na obra Systema Naturae; considerada a espécie-tipo do gênero.[1][3][15] Trata-se de uma espécie utilizada na alimentação humana[5], introduzida na costa leste da América do Norte; sendo coletada muitas vezes na costa do Pacífico, mas ainda não parecendo estar estabelecida em nenhuma região deste oceano.[16] Trata-se de uma espécie presente no território português, incluindo a zona económica exclusiva.[6]

Descrição da concha e hábitos

Concha engrossada, de espiral cônica e moderadamente alta, com dimensões aproximadas entre 1.5, 4 a 5 centímetros e 5 a 6 voltas, quando desenvolvida[6][8], globosa ou moderadamente alongada e com ápice pontiagudo; de coloração negra, cinzenta, castanha, mais raramente avermelhada ou amarelada; muitas vezes decorada com faixas onduladas e oblíquas de cor mais clara e esculpida com linhas espirais finas, atravessadas por linhas de crescimento, verticais, fracamente marcadas; com interior e columela brancos. Opérculo córneo, plano e paucispiral (com poucas voltas); auxiliando o molusco a reter água durante os períodos de estiagem.[7][8][9][17]

É encontrada em águas rasas da zona entremarés e zona nerítica, até os 60 metros de profundidade; muitas vezes expostas às ondas e aderidas às rochas, seixos, ou em planícies de marés lamacentas ou arenosas; também em bancos de mexilhões (Bivalvia), rasos ou profundos, da espécie Mytilus edulis.[6][9] Os animais da família Littorinidae se alimentam de substâncias vegetais.[18] Esses moluscos se alimentam predominantemente de diatomáceas que se fixam sobre algas, mexilhões e cracas.[6]

Distribuição geográfica

Littorina littorea ocorria no mar Mediterrâneo[9] (ocupando toda a sua extensão, no Pleistoceno, com registros até o Golfo Pérsico).[6] Ela fora relatada por Di Natale (1982) na Sicília e por Barsotti e Campani (1982) perto de Livorno, no norte do mar Tirreno. A espécie não se estabeleceu e a população perto de Livorno fora extinta em 1988 (Johannesson, 1988). As introduções, pontuais e repetidas, são prováveis porque esta é uma espécie comercial, importada para países mediterrâneos através da Irlanda ou de outras áreas de produção na Europa Ocidental.[19] Ela é comum no canal da Mancha, mar do Norte e Báltico Ocidental[9][17]; e no nordeste do oceano Atlântico: do oeste da Groenlândia ao golfo de Kandalaksha, no mar Branco, até Portugal e Espanha, na Península Ibérica.[6][15] Ela se estabeleceu, como espécie introduzida, no leste da América do Norte; e embora tenha sido encontrada na costa do Pacífico, em várias ocasiões, desde descobertas de indivíduos soltos a populações de vários milhares de caramujos, a maioria delas desapareceu.[16]

Vanlig strandsnäcka ( Swedish )

provided by wikipedia SV

Vanlig strandsnäcka (Littorina littorea) är en snäcka som tillhör familjen strandsnäckor. Den har givit namn åt Littorinahavet, ett tidigare stadium av Östersjön som fanns för 3000 år sedan som hade betydligt saltare vatten än dagens Östersjö.

Systematik

Vanlig strandsnäcka beskrevs av Carl von Linné 1758 under det vetenskapliga namnet Turbo littoreus och är typart för släktet Littorina.

Kännetecken

Den vanliga strandsnäckan har en skallängd på upp till 35 millimeter. Storleken blir mindre ju sötare vattnet är. Skalet är oftast gråbrunt men kan variera mycket i färg. Toppen på snäckan bildar en spetsig vinkel.

Utbredning

Den vanliga strandsnäckan har sitt huvudsakliga utbredningsområde i Nordeuropa och Nordamerika. I Sverige finns den på västkusten ner till sydvästra Östersjön. Under Östersjöns tidigare utvecklingsstadium Littorinahavet förekom snäckan ända upp till mellersta Norrland.

Levnadssätt

Den vanliga strandsnäckan lägger äggkapslar med 1 till 5 ägg i varje. Ungarna lever pelagiskt i tre veckor innan de sätter sig på en stenig eller klippig strand ovanför medelvattenlinjen. Vid lågvatten befinner de sig ovanför vattenytan men vid högvatten under. De livnär sig på alger. De kan parasiteras av sugmaskar som har en livscykel som fortsätter i fåglar.

Användning

Den vanliga strandsnäckan går att äta, antingen efter kokning men även rå. Man har även hittat skal på stenåldersboplatsernas avskrädeshögar.

Ốc mỡ ( Vietnamese )

provided by wikipedia VI

Ốc mỡ (danh pháp khoa học: Littorina littorea) là tên gọi chung chỉ những loài ốc biển săn mồi, là động vật thân mềm chân bụng sống ở biển trong họ Naticidae, họ ốc Mặt Trăng.[2] Các loại ốc mỡ bao gồm: ốc mỡ hoa, ốc mỡ trắng, ốc mỡ trơn...[3]Việt Nam, ốc mỡ phân bố khá phong phú và đa dạng cùng những đặc riêng có giữa các vùng miền như óc mỡ Cát Bà vỏ mịn và dẹt, không có hoa văn, ốc mỡ Đồ Sơn vỏ tròn hơn, hoa văn chấm xanh, xám, nâu, hồng sặc sỡ...

Đặc điểm

Ốc mỡ thường sống ở nước mặn ở nơi có đáy cát hoặc bùn, ăn động vật hai mảnh vỏ hoặc động vật chân bụng khác. Chúng khoan nhiều lỗ nhỏ trên vỏ của con mồi sau đó sử dụng lưỡi sừng (dãy răng kitin), chất bài tiết và sau đó chèn vòi vào để lấy dinh dưỡng, Naticid có thể tích luỹ nước ở chân và nước bắt buộc phải được đẩy ra ngoài qua những lỗ ở cuối chân trước khi thu chân vào trong vỏ.

Cái tên ốc mỡ được gọi vì khi còn sống, nhìn ốc bơi dưới nước giống như một miếng thịt mỡ nhỏ màu vàng nhạt. Về thịt, ốc mỡ ngon nhất là phần ruột. Nhiều người ăn ốc mỡ, theo thói quen chỉ ăn phần đầu, ốc mỡ nhỏ thì phần đầu còn mềm thơm, lớn hơn thì thịt vừa rắn vừa dai. Chỉ có phần đuôi của nó là có chất lượng ngon, bùi như lòng đỏ trứng vịt muối. Chính vì vậy, ốc mỡ còn là nguyên liệu để chế biến thành nhiều món ăn ngon như: ốc mỡ xào xả ớt, ốc mỡ xào satế, ốc mỡ xào me, ốc mỡ cháy tỏi, ốc mỡ rang me, ốc mỡ xào rau răm...

Раковина моллюска

Обыкновенная литорина[1], или литторина[2] (лат. Littorina littorea) — вид брюхоногих моллюсков из семейства литторин.

Обыкновенная литорина имеет яйцевидную раковину серого или черновато-бурого цвета различных оттенков, по большей части с более тёмными спиральными полосами, с острым завитком и 6—7 оборотами, разделёнными неглубоким швом. Длина раковины около 18—25 мм, реже больше. Тело моллюска желтовато-серое с чёрными точками и полосками. Питается водорослями и детритом. Размножается яйцами.

Вид распространён в северной Атлантике до Северного и Балтийского морей.

Во Франции и в части Британских островов моллюски употребляются в пищу в варёном виде.
