Dalquest (1942) observed that if a Shrew-mole is scared into hiding, it will reemerge in search of food in less than a minute. This makes them an easy target for predators, though they are not the major diet of any species (Racey,1929). Owls seem to be their biggest predator (Carraway, 1991).
Known Predators:
N. gibbsii is the smallest species of New World Talpidae (Wilson and Ruff, 1999). Its hair is black or blue-black and not as plush as other moles (Dalquest, 1942). Shrew-moles' forefeet are slightly broadened, not webbed and modified for digging only (Wilson and Ruff, 1999). The external ears are absent. Eyes are greatly reduced, and these animals have a flat, elongated nose (Carraway, 1991). The tail is about half as long as the body and reasonably wide (Reed, 1951). N. gibbsii show no sexual diamorphism and its dental formula is 3/3, 1/1, 2/2, 3/3= 36 (Carraway, 1991).
Range mass: 8 to 14.5 g.
Average mass: 10 g.
Range length: 100 to 130 mm.
Average length: 120 mm.
Other Physical Features: endothermic ; bilateral symmetry
N. gibbsii prefer soils that are easy to dig, and where there is plenty of organic matter. They are mostly found in the temperate rainforests of northwest North America, where soils are soft and deep. Shrew-moles can also be found in areas that are moist and weedy or brushy (Campbell, 2001).
Range elevation: sea level to 2500 m.
Habitat Regions: temperate
Terrestrial Biomes: rainforest
Neurotrichus gibbsii is found in western North America, from mid-California to lower British Columbia. It ranges from the Pacific Ocean to the Cascade and Sierra Nevada mountains. Shrew-moles are also found on Destruction Island, Washington (Campbell, 2001).
Biogeographic Regions: nearctic (Native )
N. gibbsii need a lots of food, compared to thier body size, because of their high metabolism. Dalquest (1942) observed that shrew-moles are capable of eating up to 1.4 times their own body weight in twelve hours and can die of starvation very quickly. He also observed that they use their nose to locate prey. He describes the process of a Shrew-mole walking up to the prey and "rapping" its nose on the ground right in front of the prey, then turning its head to the right and rapping on the ground again. It will repeate this motion, but turning its head to the left. These motions are repeated very quickly until the shrew-mole's nose touches the prey. Shrew-moles also use their long noses to push over insect pupae and isopods (Dalquest, 1942). N. gibbsii capture earthworms and other prey when they fall into the tunnels they dig. Earthworms are their prefered food (Yates,1982).
Foods eaten include: earthworms, insect larvae, snails, slugs, centipedes, sow bugs, fungus and seeds.
Animal Foods: insects; terrestrial non-insect arthropods; mollusks; terrestrial worms
Plant Foods: seeds, grains, and nuts
Primary Diet: carnivore (Vermivore)
N. gibbsii do have an effect on controlling bark beetles and other harmful insects in their own habitats. But this is of minimal economic benefit, because most areas where the shrew-mole is found are bad sites for logging or farming (Dalquest, 1942).
Positive Impacts: controls pest population
American Shrew-moles are described to be "common" throughout their range (Wilson and Ruff, 1999).
US Federal List: no special status
CITES: no special status
IUCN Red List of Threatened Species: least concern
Perception Channels: tactile ; chemical
Mating System: polygynandrous (promiscuous)
Shrew-mole has a relatively long breeding season. Reproduction happens once a year and lasts from late February to August. The length of the gestation period is unknown, but is assumed to be at least four weeks long (Yates, 1982). The nests are built above ground, although one nest was observed in a stump about a meter off the ground (Dalquest, 1942). The babies are born blind and weigh less than a gram (Wilson and Ruff, 1999).
Breeding season: usually lasts from late February to August
Range number of offspring: 1 to 4.
Average number of offspring: 3.
Average gestation period: unknown minutes.
Key Reproductive Features: gonochoric/gonochoristic/dioecious (sexes separate); sexual
Parental Investment: altricial ; female parental care

Der Amerikanische Spitzmull (Neurotrichus gibbsii) ist eine im westlichen Nordamerika lebende Säugetierart aus der Familie der Maulwürfe (Talpidae).
Der Körperbau der Amerikanischen Spitzmulle weist gewisse Ähnlichkeiten mit denen der Spitzmäuse auf. Die Vorderbeine sind nur gering verbreitert und weniger zum Graben geeignet als die anderer Maulwürfe. Das Gesicht weist eine verlängerte Schnauze auf, die Augen sind sehr klein, äußere Ohrmuscheln sind nicht vorhanden. Das weiche, dichte Fell ist dunkelgrau oder schwarz gefärbt. Mit einer Kopfrumpflänge von 7 bis 8 Zentimetern zählen sie zu den kleinsten Maulwürfen, der relativ dicke Schwanz ist mit 3 bis 4 Zentimetern Länge halb so lang wie der Körper. Das Gewicht erwachsener Tiere beträgt rund 7 bis 11 Gramm.
Das Verbreitungsgebiet dieser Tiere reicht vom südlichen British Columbia (Kanada) bis in das mittlere Kalifornien (USA) und in West-Ost-Richtung von der Pazifikküste bis zur Kaskadenkette und zur Sierra Nevada. Ihr Lebensraum reicht vom Meeresniveau bis in 2500 Metern Seehöhe. Sie bevorzugen Gebiete mit weicher Erde wie etwa gemäßigte Regenwälder. Sie sind weit verbreitet und zählen nicht zu den bedrohten Arten.
Im Gegensatz zu vielen anderen Maulwürfen halten sich Amerikanische Spitzmulle oft an der Erdoberfläche auf. Sie legen Pfade im verrottenden Pflanzenmaterial am Erdboden an, manchmal graben sie auch Gänge unterhalb der Erdoberfläche. Diese Gänge reichen bis zu 30 Zentimeter unter die Erdoberfläche und dienen ihnen vorwiegend als Ruheplätze und nur manchmal zur Nahrungssuche. Beim Graben pressen sie die Erde zur Seite und errichten keine Maulwurfshügel. Diese Tiere können gut schwimmen und klettern und suchen manchmal auch auf Büschen nach Nahrung.
Sie sind sowohl tag- als auch nachtaktiv und leben in kleinen Gruppen.
Ihre Nahrung besteht aus Regenwürmern, Asseln sowie Insekten und deren Larven. Manchmal verzehren sie auch kleine Wirbeltiere wie Salamander.
Die Paarung kann nahezu das ganze Jahr über erfolgen, es können auch mehrere Würfe pro Jahr ausgetragen werden. Die ein bis vier Neugeborenen kommen in einem Nest zur Welt, das meist auf der Erdoberfläche, manchmal sogar in Büschen bis zu 1 Meter über dem Boden liegen kann. Ansonsten ist über die Fortpflanzung wenig bekannt.
Früher wurden Amerikanische Spitzmulle gemeinsam mit den Japanischen Spitzmullen, die eine ähnliche Lebensweise führen, in einer gemeinsamen Gattungsgruppe Spitzmulle (Urotrichini) zusammengefasst. Die Ähnlichkeiten mit diesen Tieren dürften allerdings lediglich auf Konvergenz beruhen.

The American shrew mole (Neurotrichus gibbsii) is the smallest species of mole. It is the only living member of the genus Neurotrichus and the tribe Neurotrichini. It is also known as Gibb's shrew mole and least shrew mole.[3] It is not closely related to the Asian shrew mole (Uropsilus in Urotrichini). The reason that it is called a "shrew mole" instead of being called either a "shrew" or a "mole" is because of its fur, which is a characteristic of shrews and its large head and heavy dentition, which is characteristic of moles.[4]
It is found in damp, forested or bushy areas with deep, loose soils in the northwestern United States and southwestern British Columbia. In the most northern part of its habitat, it lives along streams or moist dense woods and in the most southern part of its habitat, it is found in swampy areas that are overgrown with vegetation such as sedges or shrubs.[5]
Like shrews, it has a pelage with guard hairs and underfur.[4] Its fur is dense and soft. The color ranges from dark gray to a sooty bluish-black.[4] Its tail is about half the length of its head and body.[4] Its tail is also covered with scales and scattered coarse hairs.[4] It has a long, flattened snout, and a short but thick, bristled tail. It is the smallest of the American moles.[4] It is about 10 cm (3.9 in) in length including a 3 centimetres (1.2 in) tail, and weighs about 10 g (0.35 oz). It has a zygoma and auditory bullae, which are absent in shrews, but present in moles.[6] The enamel that covers its teeth is white instead of mahogany or reddish-brown, like it is in shrews.[6] It also lacks a penis bone.[6] Its front paws are smaller and do not face outwards from the body as in more fossorial moles, and so are more similar to those of shrews. The front paws are also broad with bifurcate phalanges, which provide more support for the claws in order to dig.[6] Also, the three middle claws of the front paws are elongated and the eyes are also completely covered by skin.[4]
In addition to the front paws, the rest of its morphological features allow it to be highly fossorial and subterranean.[6] It has a streamlined body that allow it to move smoothly through tunnels and short appendages that are kept close to the body.[6] It also has no ear pinnae, which is the external part of the ear.[6] These features reduce drag when it digs and when it moves through tunnels.[6]
The shrew-mole is often confused with pocket gophers, another group of fossorial subterranean mammals, because they have similar habits but they differ greatly in the methods for burrowing.[6] Most fossorial mammals, including the pocket gophers dig with their forepaws held directly below their body, but shrew-moles dig using lateral-strokes.[6] This method of lateral-stroke burrowing in shrew moles is an evolutionary adaptation due to the modification of the pectoral girdle and bones of the forelimbs.[6] The pelvic girdle is small and unmodified, but the pectoral girdle contains a special joint that causes the clavicle to join with the humerus instead of the scapula.[6] The humerus bones are unique to shrew-moles because they exist as massive rectangular shapes, unlike other fossorial mammalian groups.[6] The humerus also has a large surface area for the attachment of well developed muscles used for digging.[6]
The shrew-mole makes permanent tunnels by digging with its forelimbs and using its forefeet to soften the soil that will be removed to make a hollow tunnel.[6] The tunnels form complex networks that interconnect and lead to burrows.[6] The tunnels are rarely ever deeper than 30 centimeters below the surface, so they are not as deep as the tunnels of other mole species.[6] The burrows are made beneath decaying leaf litter and have an opening on the ceiling that leads to the surface, which serves the purpose of ventilation.[6] The shrew-mole also makes shallow surface runways by moving the front part of its body 45 degrees to the right and then to the left. Then back again to the right, then left, and so on. When it moves to the right, the left forepaw is thrust up rapidly lifting soil in the process and when it moves to the left, the right forepaw is thrust up to lift soil.[6]
As the shrew-mole continues to dig through the soil, the amount of prey in the soil is significantly less than the amount present in soil that has not been dug through by them.[6] In addition, it spends a lot of its energy to dig through the soil.[6] Due to these factors, it is common for shrew-moles to forage through tunnels that have been dug by other shrew-moles because it is more energetically efficient and more prey might be present in tunnels that have been abandoned.[6]
It has a long and narrow rostrum, which is the projection that forms the snout.[6] The junction between the skull bones turns into bone early on in their age, which makes it difficult to identify their age based on looking at their skull bones.[6] The maxillary only turns into bone in the adults and the roots of the upper molars are exposed in immature shrew-moles.[6] The first upper incisor is flat and it does not have an elongated crown, like shrew do.[6] It has 36 teeth, which consist of incisors, canines, pre-molars, and molars.[5]
This mole is often active above ground, foraging in leaf litter for earthworms, insects, snails and slugs. It is also known to eat some vegetation such as mycorrhizal fungi and even salamanders, but earthworms are the most important food item in its diet.[6] Its diet also depends on the type of available food sources, so it may eat more vegetation than anything else if there are no insects or other arthropods within its vicinity.[5] It is able to climb bushes to forage for food, although that is not its main eating resource.[6]
Like all shrew-moles, the stomach size of this shrew mole in inversely proportional to its body weight.[6] Their intestinal tract is quite short and digestion occurs rapidly.[6]
Predators include owls, hawks and mustelids such as weasels, fishers, and pine martens. Additional predators include red and gray foxes, raccoons, and skunks.[6] Dogs and cats can kill them as well, but do not eat them.[6] Venomous and non-venomous snakes, bullfrogs, and opossums have also been reported to hunt them.[6]
The most common ectoparasites found on these shrew moles are fleas and mites.[4]
The endoparasites found in shrew-moles consist of twenty species of coccidian protozoans, at least five species of nematode, two species of trematode, and two species of acanthocephalan.[6]
When underground shrew-moles can suffer from a low levels of oxygen, high levels of carbon dioxide, and high levels of humidity.[6] In order to cope with these conditions, shrew-moles contain lungs that can hold large volumes and sometimes even more than 20% of their body weight.[6]
They also experience stages of sleep that are similar to humans such as rapid eye movement sleep.[6] It is believed that the reason why they experience stages of deep sleep is because they are subject to less danger than other mammals.[6]
They have well developed hearing.[6]
The shrew-mole has 38 chromosomes.[6] The sex chromosomes are XX in females and XY in males.[6] The Y chromosome in males is very small and appears to be similar in all species.[6]
It can have several litters annually, though no litters have been recorded between December and January.[4] Females have litters with one to four young. Newborns are about 30 millimeters long and weigh less than 1 gram.[4]
In females, the vagina remains sealed until follicles appear in the ovaries.[6] Males lack a scrotum, but the testes and associated glands become enlarged, which increases their weight.[6] These characteristics make it difficult to externally determine the sex of shrew-moles.[6]
It is somewhat gregarious, which means that it lives in loosely organized communities of about 12 to 15 shrew moles.[4] The only known type of vocalization that they produce is a faint twittering sound that can be heard for several feet.[4] It is both diurnal and nocturnal.[4]
Shrew-moles usually live in areas where it is difficult to cultivate so they are usually economically neutral, but there are some cases where they do damage people's homes.[6] There are many different methods that people use for getting rid of these moles. The most common non-commercial method is trapping because it is practical for homes with little land, but unpractical for large areas of land.[6] Other methods include catching moles by spading where a spade is put behind the mole as it creates a surface tunnel or repairs a tunnel and is then lifted up or by hand, where the mole is picked up by its fur.[6] Chemical control agents can also be used.[6] Using bait is another method used to control these shrew-moles. The bait usually consists of some type of cereal grain that is treated with chemicals.[6] The type of cereal grain and chemicals used depends on the manufacturer, but a common chemical is an anticoagulant that inhibits their normal platelet function in the blood, which causes internal hemorrhaging and leads to death.[6] Some other approaches are to force the animal away somehow or to get rid of their food source.[6]
There are also many home remedies that are used to get rid of these shrew-moles, but whether or not these methods are successful are usually not evident.[6] These methods include using noisemaker devices such as placing empty soft drink bottles at an angle with the bottom in the tunnel while the neck is sticking.[6] It is believed by some that the sound that the wind produces as it goes through the bottle scares the shrew-moles away.[6] Materials consisting of offensive and unpleasant smells and materials that cause injury are also sometimes placed in the tunnels such as broken pieces of glass, razors, exhaust fumes, moth balls, gum, and thorns.[6]

It is also known as Gibb's shrew mole and least shrew mole. It is not closely related to the Asian shrew mole (Uropsilus in Urotrichini).

La Taupe naine ou Taupe de Gibbs (Neurotrichus gibbsii) est une espèce de mammifères de la famille des Talpidés (Talpidae). Cette taupe miniature se rencontre sur la côte ouest de l'Amérique du Nord où l'on distingue plusieurs sous-espèces. C'est la seule espèce encore vivante du genre Neurotrichus qui ne compte par ailleurs que des fossiles.
Neurotrichus gibbsii est une minuscule taupe à l'allure de musaraigne, ce qui lui vaut le nom de Shrew-mole (soit taupe musaraigne) en Amérique[5].
Cette espèce ne présente pas de dimorphisme sexuel. Le mâle et la femelle mesurent tous deux entre 9,2 et 13,2 cm, en moyenne 11,4 cm, pour un poids compris entre 9 et 11 g[5].
Elle est réputée avoir un système X0 de détermination du sexe, donc des spermatozoïdes qui contiennent soit un chromosome X soit aucun[6].

Face ventrale
C'est un animal terrestre actif toute l'année. Elle se déplace plutôt en groupe, contrairement à la plupart des insectivores. Aveugle, elle se repère à l'odorat, à l'aide son museau effilé[6].
La période de reproduction se situe au printemps, de mars à mi-mai, une partie seulement des femelles mettent bas par la suite, dans un nid, une portée qu'elle allaite, allant de 1 à 4 petits[6].
C'est un animal vorace qui engloutie quotidiennement plus que son poids de nourriture. C'est principalement un insectivore, à tendance omnivore puisqu'elle mange occasionnellement des graines, des champigons ou des lichens en plus de sa ration habituelle d'invertébrés (vers, gastéropodes, insectes...)[6].
Cette taupe est originaire de l'ouest du Canada (Colombie-Britannique) et des États-Unis (Californie, Oregon, État de Washington). Elle y est suffisamment répandue pour que ses populations ne soient pas menacées de déclin. C'est une espèce moins fouisseuses que les autres taupes et qui se plait dans les zones humides sans herbages[6].
Cette espèce a été décrite pour la première fois en 1857 par le zoologiste américain Spencer Fullerton Baird (1823-1887) sous le nom de Urotrichus gibbsii. C'est l'espèce type du genre Neurotrichus[7].

Neurotrichus gibbsii är ett däggdjur i familjen mullvadsdjur (Talpidae) och den enda arten i sitt släkte. Den förekommer i Nordamerika.
Arten påminner mer om en näbbmus än om en mullvad. De främre fötterna är inte lika förstorade som hos andra mullvadsdjur och arten har mindre förmåga att gräva. Nosen är långsträckt, ögonen är små och yttre öron saknas. Den täta mjuka pälsen har en mörkgrå till svart färg. Med en kroppslängd mellan 7 och 8 cm (utan svans) är arten en av de minsta av alla mullvadsdjur. Svansen är jämförelsevis tjock och 3 till 4 cm lång. Vuxna individer når en vikt mellan 7 och 11 gram.
Utbredningsområdet sträcker sig från södra British Columbia (Kanada) till centrala Kalifornien (USA). Österut finns den till Kaskadbergen och Sierra Nevada. Den lever även i bergsregioner upp till 2 500 meter över havet. Neurotrichus gibbsii föredrar mjuk jord främst i tempererade regnskogar.
Individerna vistas främst på marken. De skapar stigar genom att trampa ned växtligheten och sällan gräver de tunnlar. Gångarna ligger vid vissa ställen 30 cm under markytan. De används främst som viloplats och sällen för att leta efter föda. Vid ingången finns inga jordhögar. Neurotrichus gibbsii har bra förmåga att simma och klättra i buskar.
De kan vara aktiva på dagen och på natten och bildar mindre grupper.
Födan utgörs huvudsakligen av daggmaskar, gråsuggor samt insekter och deras larver. Ibland äter de mindre ryggradsdjur som groddjur.
Honor kan para sig hela året och ibland förekommer flera kullar per år. Boet för ungarna byggs antingen på marken eller i buskar. Per kull föds en till fyra ungar. Annars är inte mycket känt om deras fortplantningssätt.
Tidigare listades arten tillsammans med två arter från Japan till släktgruppen Urotrichini. Alla tre mullvadsdjuren liknar sig i levnadssättet men dessa likheter beror troligen på konvergent evolution.
