Holohepatica
The Doridina, common name dorid nudibranchs, are a taxonomic suborder of sea snails or slugs, marine gastropod molluscs in the order Nudibranchia. Bouchet & Rocroi (2005) rejected the name Anthobranchia on the grounds that it also included ''Onchidium'' at the time of original publication. Doridina is equivalent and used in the latest classification.Bouchet P., Rocroi J.P., Hausdorf B., Kaim A., Kano Y., Nützel A., Parkhaev P., Schrödl M. & Strong E.E. (2017). Revised classification, nomenclator and typification of gastropod and monoplacophoran families. Malacologia. 61(1-2): 1-526. A morphological phylogenetic study, published in 2000, by Wägele & Willan showed that the subclade Gnathodoridacea (= Bathydoridoidea) and the subclade Doridacea (= Phanerobranchia + Cryptobranchia + Porostomata) each form a monophyletic group. In a later study, published in 2002, A. Valdés concluded that the superfamilies Doridoidea and Phyllidioidea (called by him Cryptobranchia + Porostomata ...

Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks. (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater.) The paper setting out this taxonomy was published in the journal ''Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder ...

Yellow-edge Cadlina
''Cadlina luteomarginata'', common name the yellow-edged cadlina, is a species of colorful sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Cadlinidae.Caballer, M.

Mandeliidae
Mandela's nudibranch, ''Mandelia mirocornata'', is a species of sea slug, a dorid nudibranch. It is a marine gastropod mollusc, the only member of the genus ''Mandelia'' and the family Mandeliidae. The genus and family name honor Nelson Mandela, the former President of South Africa. Distribution This species has so far only been found around the southern African coast from the Atlantic coast of the Cape Peninsula to Port Elizabeth in 10–400 m of water. It is probably endemic. Description Mandela's nudibranch has a bumpy dirty white to brown skin. It has black spots scattered over the notum. Its gills and rhinophores are large and creamy-coloured. The rhinophores are perfoliate, but are oblong rather than round. The animal may also have irregular brown stripes rather than spots on the notum, radiating out to the margins. It may reach a total length of 70 mm.ZSILAVECZ, G. 2007. ''Nudibranchs of the Cape Peninsula and False Bay''. Ecology This species feeds on sponges. S ...

Phyllidiidae
Phyllidiidae is a family of sea slugs, dorid nudibranchs, marine gastropod mollusks in the superfamily Phyllidioidea. This family is within the clade Doridacea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). Distribution Most species occur in the tropical Indo-Pacific region, but a few species have been found in the tropical Atlantic Ocean and in the Mediterranean. Description The mantle of these oval nudibranchs is flattened dorsoventrally and its dorsal surface is covered with hard, colored tubercles. This mantle is decorated with contrasting colors and patterns as warning signals to predators. The lamellate rhinophores can be retracted. Like other dorid nudibranchs, all species have a dorsal anus, except for the species in the genus ''Fryeria'' where the anus is posteroventral and protrusible. In contrast with the other nudibranchs from the clade Doridacea, the species in this family lack buccal armature, i. e. radulae and jaws. The gill leaflets a ...

Discodorididae
Discodorididae is a taxonomic family of sea slugs, specifically dorid nudibranchs, marine gastropod mollusks in the superfamily Doridoidea.Bouchet, P. (2011). Discodorididae. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=1761 on 2011-08-23 Species in this family belong to the cryptobranch dorid nudibranchs, i.e. they are able to retract their gills into a gill pocket (cryptobranch = hidden gills). Most are small and hard to identify. Most are thought to feed at night on sponges, while during the day they search for dark areas or remain hidden under rocks. One example of a discodoridid is the "Pacific sea lemon" or "speckled sea lemon", ''Peltodoris nobilis'', which occurs off the coast of British Columbia to Baja California from low-tide waters to a depth of about 200 m. Not only is this species yellow with a bumpy surface, but it also gives off a strong fruity citrus smell when handled, adding to its resemblance ...

Chromodorididae
Chromodorididae, or chromodorids, are a taxonomic family of colourful, sea slugs; dorid nudibranchs, marine gastropod mollusks in the superfamily Doridoidea. “Chromodorid nudibranchs are among the most gorgeously coloured of all animals.” The over 360 described species are primarily found in tropical and subtropical waters, as members of coral reef communities, specifically associated with their sponge prey. The chromodorids are the most speciose family of opisthobranchs. They range in size from <10mm to over 30 cm, although most species are approximately 15–30 mm in size. Although, they have a worldwide distribution, most species are found in the region.

Dorididae
Sea lemon is a loosely applied common name for a group of medium-sized to large shell-less colorful sea slugs or nudibranchs, specifically dorid nudibranchs in the taxonomic family Dorididae and other closely related families. These are marine gastropod mollusks. The Monterey sea lemon is ''Doris montereyensis'' and the mottled pale sea lemon is '' Diaulula lentiginosa''. The common name sea lemon probably comes from these animal's visual similarity to a lemon based on such qualities as the roughened skin, the oval form when seen from above, and the common but not inevitable orange to pale yellow coloration. Description These dorid nudibranchs can be large (up to 20 cm), rather flattened, and oval in shape when seen from above. They have two hornlike projections (rhinophores) on the head, and a rosette-like tuft of gills on the back of the animal. The mantle is sometimes sprinkled with black dots, and it is covered in small bumps, which are called tubercles. Life habits S ...
