Facelina is a genus of sea slug, an aeolid nudibranch in the family Facelinidae. [2]
Species within the genus Facelina include:
The Polyceridae are a taxonomic family of sea slugs, dorid nudibranchs, marine gastropod mollusks within the superfamily Polyceroidea.
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.
Aldisa is a genus of sea slugs, dorid nudibranchs, marine gastropod molluscs in the family Cadlinidae.
Polycera is a genus of sea slugs, specifically nudibranchs, shell-less marine gastropod molluscs in the family Polyceridae.
Doris is a genus of sea slugs, specifically dorid nudibranchs. These animals are marine gastropod molluscs in the family Dorididae.
Atagema is a genus of sea slugs, specifically dorid nudibranchs. They are 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.
Dendrodoris is a genus of nudibranchs, marine gastropod molluscs in the family Dendrodorididae.
Doriopsilla is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod molluscs in the family Dendrodorididae.
Caloria is a genus of colorful sea slugs, aeolid nudibranchs. They are marine gastropod molluscs in the family Facelinidae.
Goniodoris is a genus of sea slugs, specifically dorid nudibranchs, marine gastropod molluscs in the family Goniodorididae.
Onchidoris is a genus of dorid nudibranchs in the family Onchidorididae. One of its members is known to prey on barnacles and the others eat bryozoans. The radula contains a rachidian tooth when fully developed, but this is vestigial in some species.
Discodoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod molluscs in the family Discodorididae.
Thordisa is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae.
Phyllidiopsis is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod molluscs and is the largest genus within the family Phyllidiidae.
Hermaea is a genus of sacoglossan sea slugs, a shell-less marine opisthobranch gastropod mollusks in the family Hermaeidae.
Facelina auriculata, sometimes known by the common name Slim Aesop, is a species of sea slug, an aeolid nudibranch in the family Facelinidae.
Aeolidiella is a genus of sea slugs, aeolid nudibranchs, marine gastropod molluscs in the family Aeolidiidae.
