Philiopsis is a genus of often colorful, medium-sized sea slugs, marine opisthobranch gastropod mollusks. These are not nudibranchs; instead they are headshield slugs, in the clade Cephalaspidea. [1]
(Original description) Animal: The head disk is large, oblong-oval to triangular in shape, and does not extend beyond the foot. Behind the head disk, the body forms a convex, fleshy lobe that begins beneath the overlapping head disk and extends to or just past the posterior portion of the foot. This lobe is truncated at the rear, with the truncation bordered by an undulated or crenated crest. Eyes are not visible. The mouth is proboscidiform, positioned between the cephalic disk and foot, and may have a pair of tentacles on either side. The foot is large, rounded, and reflected at the sides. A branchial plume is located near the posterior end of the body, curving around near the truncated end of the foot. The shell is concealed within this truncated end. [2]
Recognized species within the genus Philinopsis are: [1]
Aglajidae is a family of often colorful, medium-sized, sea slugs, marine opisthobranch gastropod mollusks. These are not nudibranchs; instead they are headshield slugs, in the clade Cephalaspidea.
Elysia is a genus of sea slugs, marine gastropod molluscs in the family Plakobranchidae. These animals are colorful sea slugs, and they can superficially resemble nudibranchs, but are not very closely related to them. Instead they are sacoglossans, commonly known as sap-sucking slugs.
Chromodoris is a genus of very colourful sea slugs or dorid nudibranchs, marine gastropod molluscs, and the type genus of the family Chromodorididae. Within the genus Chromodoris, there are currently 101 classified species. Species within Chromodoris are commonly found in tropical and subtropical waters, living as members of reef communities and preying primarily on sponges. A molecular phylogeny of the family Chromodorididae resulted in this genus being restricted to a smaller number of species than formerly, most of which have longitudinal black lines on the mantle. Many former members of Chromodoris were transferred to Goniobranchus
Tritonia is a genus of sea slugs, nudibranchs, shell-less marine gastropod molluscs in the family Tritoniidae.
Chelidonura is a genus of small, sometimes colorful, sea slugs. These are headshield slugs or cephalaspideans, marine opisthobranch gastropod mollusks in the family Aglajidae.
Philine is a genus of sea slugs or sea snails, marine gastropod molluscs in the subfamily Philininae of the family Philinidae, the headshield slugs or paper bubbles.
Hypselodoris is a genus of colourful sea slugs or dorid nudibranchs, marine gastropod mollusks in the family Chromodorididae. Modern usage follows a more restricted view of which species belong in this genus so there are numerous genus transfers.
Glossodoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Chromodorididae.
Flabellina is a genus of sea slugs, specifically aeolid nudibranchs. These animals are marine gastropod molluscs in the family Flabellinidae.
Jorunna is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod molluscs in the family Discodorididae.
The Facelinidae are a taxonomic family of colorful sea slugs. These are specifically aeolid nudibranchs. They are marine gastropod molluscs.
Hermaeidae is a taxonomic family of sacoglossan sea slugs. These are marine opisthobranch gastropod mollusks in the superfamily Plakobranchoidea.
Taringa is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod molluscs in the family Discodorididae.
Verconia is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Chromodorididae.
Paradoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae.
Aegires is a genus of sea slugs, dorid nudibranchs, marine gastropod mollusks in the family Aegiridae. Species within this genus feed exclusively on calcareous sponges.
Peristernia is a genus of sea snails, marine gastropod mollusks in the subfamily Peristerniinae of the family Fasciolariidae, the spindle snails, the tulip snails and their allies.
Notodoris is a genus of sea slugs, dorid nudibranchs, marine gastropod molluscs in the family Aegiridae. It has been treated as a synonym of Aegires but re-established on the basis of radula and jaw characters.
Melanochlamys is a genus of headshield slugs in the family Aglajidae. Despite the appearance of its species, this genus must not be confused with nudibranchs.
Aglaja is a genus of sea slugs, marine opisthobranch gastropod mollusks in the family Aglajidae. The genus is found in all warm and temperate oceans.
