Umbraculum umbraculum ( англиски )

добавил wikipedia EN

Umbraculum umbraculum, common name the umbrella slug, is a species of large sea snail or limpet, a marine gastropod mollusc in the family Umbraculidae.[2] It is found in tropical to warm temperate parts of the Indo-Pacific and Atlantic Oceans, where it feeds on sponges.

Description

Umbraculum umbraculum is a large mollusc growing to a length of up to 20 cm (8 in), with a relatively small external shell on the dorsal surface. This shell is a flattish cone and is usually encrusted with epiphytic organisms, both plant and animal. The mantle is roughly circular in outline, and is covered with pustules; the ground colour of the mantle varies, usually being orange or brownish, and the pustules are usually white. The mollusc does not elongate when crawling and the location of the head is revealed when it thrusts out its rolled rhinophores from beneath the shell. At the base of the rhinophores are a pair of eyes, and beneath is a cleft which contains the mouth. The radula is broad and is armed with many small teeth.[3][4] The sole of the foot is smooth and flat; the gills are bipinnate and are located in the right side of the body.[5]

Distribution and habitat

Umbraculum umbraculum is found in the Pacific Ocean in both the tropics and in warm temperate regions. Its range includes Indonesia, Australia, New Zealand, Hawaii, Mexico and Panama.[4] It also occurs in the Red Sea, the Mediterranean Sea and the warmer parts of the Atlantic Ocean. In 2016, researchers reported that it had been observed for the first time in the Bay of Biscay in surveys undertaken between 2011 and 2014, in what seemed to be a northward shift in its range; this "tropicalisation" was attributed to a rise in sea temperature.[5] It occurs in both shallow water and at depths down to about 275 m (900 ft).[4]

Ecology

Umbraculum umbraculum feeds on sponges and its colouring often makes it well camouflaged. It rasps the surface of the sponge with its radula, opening the cleft on its base wide so that it can press its mouth against the surface of the sponge. This slug has been found on Tethya spp., Aaptos aaptos, Ancorina alata and Plakina trilopha.[3] The eggs are laid in a long, coiled ribbon and the larvae are planktonic.[5]

Description

 src=
Planche d’illustration de Umbraculum umbraculum datant de 1852

Cette espèce peut mesurer jusqu'à 20 cm de diamètre. Le corps est circulaire, couvert de tubercules aux extrémités arrondies. L'animal possède une coquille légèrement conique sur le dessus du corps, toutefois cette dernière est de taille plus réduite que le corps (7 cm max) et ne lui permet pas de s'y cacher. Celle-ci est souvent couverte d'épibiontes. La coloration du corps est fonction de son régime alimentaire mais la teinte varie du beige clair à l'orange vif en passant par le jaune. Les rhinophores, jaune orangé, sont lisses et tubulaires, situés juste sous la coquille et permettent d'identifier la partie antérieure du corps.La branchie est latérale, située sur la face droite du corps sous la coquille, et parfois observable[2].

La ponte est un long ruban orange, contenant plusieurs millions d’œufs[2].

Distribution

Cette espèce cosmopolite se rencontre dans les eaux tropicales et tempérées des trois grands bassins océaniques[2].

Habitat

Son habitat correspond à la zone récifale externe, sur les platiers et dans les lagons, avec une prédilection pour les secteurs sablo-vaseux à proximité directe d'éponges et ce jusqu'à 50 m de profondeur (mais on la rencontre occasionnellement jusqu'à plusieurs centaines de mètres de profondeur)[2].

Éthologie

Cette espèce est benthique et nocturne. La journée, il vit enfoui dans le substrat meuble ou dans une éponge creusée[2].

Alimentation

Umbraculum umbraculum se nourrit d'éponges diverses, notamment des démosponges[2].
