Onchidella Binneyi
''Onchidella binneyi, also known as Onchidella carpenteri, Onchidium carpenteri,'' and ''Oncidiella hildae,'' is a species of air-breathing sea slug, a shell-less marine pulmonate gastropod mollusk in the family Onchidiidae. Description The ''Onchidella binneyi'' are dark grey sea slugs around 2-3 centimeters in length. They produce a defensive secretion as protection against predators because of the absence of the typical defense mechanism of other gastropods, an external shell. This defensive secretion contains the compound Onchidal, which acts as a feeding deterrent. Released after the initial attack, the effect on the predator is irreversible. Onchidal causes the predator to forego the sea-slug as a meal option. The toxicity level to predators and humans is not well known. Distribution This species is found along the western coast of the Pacific from the Bahia de Los Angeles in the Gulf of California to Ecuador. ''Onchidella binneyi'' are found in the upper intertidal zones ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onchidella Celtica
''Onchidella celtica'' is a species of air-breathing sea slug, a shell-less marine pulmonate gastropod mollusk in the family Onchidiidae. The complete nucleotide sequence of the mitochondrial genome of Onchidella celtica has been available since 2008.Grande C., Templado J. & Zardoya R. 2008''Evolution of gastropod mitochondrial genome arrangements'' BMC Evolutionary Biology 2008, 8:61. Description ''Onchidella celtica'' is up to 12mm long and its oval body has a deep olive to black colour. The mantle is covered with large tubercles which concealed the head and the foot of the animal when motionless. The eyes are at the tips of two short and thick tentacles and are visible from above when the animal is crawling. Distribution This species occurs locally on the East Atlantic coastline, from western Scotland, western England and the Channel Islands, south to Spain and the Azores, including: * Great Britain *Coastline of Brittany Habitat This air-breathing sea slug lives in the ...

Onchidiidae
Onchidiidae are a family of small, air-breathing sea (and land) slugs. They are shell-less marine (except for 2 species)preview pulmonate gastropod molluscs. Onchidiidae is the only family within the superfamily Onchidioidea. These animals are quite unusual in that they are emphatically not opisthobranchs with gills, as are almost all of the sea slugs. Instead these creatures are pulmonates. They are more closely related to air-breathing land and freshwater snails and slugs than they are to most other sea snails and sea slugs. This family has no subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). 143 species names were created within the Onchidiidae, but until recently few species could be identified. In the late 1920s Hoffmann revised the family (based on the descriptions), and classified the described species into genera. Labbé later continued the revision and named many new genera in his classification of onchidiid slugs. Labbé also made m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
