Acanthodoris
''Acanthodoris'' is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Onchidorididae.Gofas, S. (2015)''Acanthodoris'' Gray, 1850.In: MolluscaBase (2015). Accessed through: World Register of Marine Species on 2016-01-09 The genus is believed to have originated in the Atlantic Ocean in the Cretaceous period and spread to the Pacific Ocean. The relationships of ''Acanthodoris'' to the other genera in the family Onchidorididae were evaluated by molecular phylogeny in 2015.Hallas, JM and Gosliner, TM. (2015) ''Family Matters: the first molecular phylogeny of the Onchidorididae (Mollusca, Gastropoda, Nudibranchia).'' Molecular Phylogenetics and Evolution, 88: 16–27.

Acanthodoris Lutea
''Acanthodoris lutea'', the orange-peel doris, is a species of nudibranch or sea slug, a shell-less marine opisthobranch gastropod mollusk in the family Onchidorididae. This species is the largest of the northeastern Pacific onchidorids.Behrens D.W., 1980, ''Pacific Coast Nudibranchs: a guide to the opisthobranchs of the northeastern Pacific'', Sea Challenger Books, Washington, 112pp., p. 48. It is a common species, and it is very noticeable because of its bright coloration, which is aposematic. The species name "''lutea''" is a Latin word which means an orange-yellow color. The generic name, "''acantho''" comes from the Greek word meaning spiny, and "'' doris''" is the name of an ancient Greek sea nymph. Description This nudibranch grows to about 30 mm in length. It has a bright orange papillated dorsum covered with yellow specks. As is the case with many nudibranchs, this bright coloration is thought to be a reminder to would-be predators of its distasteful nature, an ...

Acanthodoris Pilosa
''Acanthodoris pilosa'' is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusc in the family Onchidorididae.

Description ''Acanthadoris pilosa'' grows to a length of about , or occasionally as much as . It gives the impression of being fluffy because the body is covered with long, fleshy pointed papillae. At the head end are two rhinophores, much larger than the papillae, which house the sensory organs; these typically are bent towards the rear of the animal. At the posterior end there is a distinctive ring of up to nine gills. This sea slug has a uniform colour which may be anything from whitish to pale purplish-brown to darker brown or charcoal grey. Juveniles are often speckled. Distribution This specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
