Teardrop butterflyfish

provided by wikipedia EN

The teardrop butterflyfish (Chaetodon unimaculatus) is a species of marine ray-finned fish, a butterflyfish belonging to the (family Chaetodontidae. It is found in the Indo-Pacific region.

Description

The teardrop butterflyfish has a whitish body with yellow dorsal, anal and pelvic fins,[3] this yellow colour extends on to the back.[4] The upper flank is marked with a large teardrop shaped black blotch and there is a wide, black, vertical bar though the eye. There are delicate yellowish-orange chevrons on the flanks in front of the black teardrop and there is another black vertical band with runs from the rear of the dorsal fin, across the caudal peduncle to the rear of the anal fin.[3] The dorsal fin contains 12-13 spines and 19-23 soft rays while the anal fin contains 3 spines and 18-20 soft rays. This species attains a maximum total length of 20 centimetres (7.9 in), although around 16 centimetres (6.3 in) is more usual.[2]

Distribution

The teardrop butterflyfish is found in the eastern Indian and western Pacific Oceans from Christmas Island and Cocos (Keeling) Island east as far as Hawaii, the Marquesas and Ducie Island, north as far as Southern Japan, and south to Lord Howe in the Tasman Sea and the central coast of New South Wales.[5][3]

Habitat and biology

Teradrop butterflyfish are normally encountered in small groups in reef flats, clear lagoon and seaward reefs where they feed on soft and hard corals, as well as polychaetes, small crustaceans and filamentous algae. This is an oviparous species and they are monogamous with the sexes forming pairs to breed.[2] These fishes may be found at depths of 1 to 60 metres (3.3 to 196.9 ft) and they are most numerous where the leathery corals of the genera Sarcophyton and Sinularia grow.[1]

Taxonomy

The teardrop butterflyfish was first formally described in 1787 by the german medical doctor and zoologist Marcus Elieser Bloch ((1723-1799) with the type locality give as the East Indies, i.e. Indonesia.[6] In the western Indian Ocean it is replaced by the yellow teardrop butterflyfish (Chaetodon interruptus), now a separate species but previously considered a subspecies of Chaetodon unimaculatus.[1]

In its subgenus Lepidochaetodon it is sometimes considered a separate genus. It is only distantly related to other Chaetodon species such as the sunburst butterflyfish (Chaetodon kleinii) and the Tahiti butterflyfish (Chaetodon trichrous).[7][8]

Utilisation

The teardrop butterflyfish is relatively common in the aquarium trade. It is caught by some artisanal fisheries.[1]

Pisaraperhokala kasvaa 20 cm korkeaksi. Sen vartalo on litteä, kelta-valko-mustakuvioinen. Silmän läpi kulkee musta juova, ja selkäevän tyvessä on musta pisara.

Alkuperä

Pisaraperhokala elää Fidžillä, Indopasifisella merialueella, Sri Lankan ja Havaijin ympäristössä. [2] Aikuiset yksilöt pysyttelevät 20–60 metrin syvyydessä.

Käyttäytyminen

Pisaraperhokala on yksiavioinen ja muodostaa pareja kutuajaksi. Muulloin ne liikkuvat pienissä parvissa.

Vesiolot ja ravinto

Pisaraperhokala syö koralleja, äyriäisiä ja levää.

Poisson-papillon à larme du Pacifique ( French )

provided by wikipedia FR

Poisson-papillon larme, Poisson-papillon à une tache

Chaetodon unimaculatus, communément nommé Poisson-papillon larme ou Poisson-papillon à une tache, est une espèce de poissons marins de la famille des Chaetodontidae.

Sous-genre

Le poisson-papillon à larme du Pacifique est un poisson-papillon qui fait partie du sous-genre Lepidochaetodon. En 1984, André Maugé et Roland Bauchot ont proposé d'affecter cette espèce à leur nouveau genre Heterochaetodon, ce qui donnerait comme nom scientifique pour ce poisson Heterochaetodon unimaculatus.

Description

La taille maximale du Poisson-papillon larme est de 20 cm mais la taille moyenne couramment observée est de 16 cm[1].

Sa coloration est jaune vers le haut, blanche vers le bas, avec une large bande verticale noire passant par l'œil, et une tache noire au milieu du corps (vers le haut), tache qui peut faire penser à une goutte d'eau retournée ou à une larme.

Distribution

Le poisson-papillon larme se rencontre dans la région Indo-Pacifique[2].

Biologie et écologie

Le Poisson-papillon larme apprécie les platiers récifaux, les lagons aux eaux claires avec une prédilection pour les zones riches en corail cuir comme les espèces du genre Sarcophyton et Sinularia et ce de la surface à 60 m de profondeur. Il a une activité diurne et est coralivore[3].
