Sacoglossa, commonly known as the sacoglossans or the "solar-powered sea slugs", are a superorder of small sea slugs and sea snails, marine gastropod mollusks that belong to the clade Heterobranchia. Sacoglossans live by ingesting the cellular contents of algae, hence they are sometimes called "sap-sucking sea slugs".
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.
Plakobranchidae is a family of sea slugs, marine opisthobranch gastropod mollusks in the superfamily Plakobranchoidea. They superficially resemble nudibranchs but they are sacoglossans, members of the clade Sacoglossa within the Opisthobranchia.
Stiliger is a genus of small and minute sacoglossan or sap-sucking sea slugs. They are marine gastropod mollusks in the family Limapontiidae.
Placida is a genus of very small or minute sea slugs, marine opisthobranch gastropod mollusks in the family Limapontiidae.
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.
Placida dendritica is a species of minute sea slug, a marine opisthobranch gastropod mollusk or micromollusk in the family Limapontiidae.
Aeolidiidae, a family of aeolid nudibranchs, are a family of sea slugs, shell-less marine gastropod molluscs.
Glossodoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Chromodorididae.
Polycera is a genus of sea slugs, specifically nudibranchs, shell-less marine gastropod molluscs in the family Polyceridae.
The Facelinidae are a taxonomic family of colorful sea slugs. These are specifically aeolid nudibranchs. They are marine gastropod molluscs.
Bosellia is a genus of sea slugs, marine gastropod mollusks within the superfamily Plakobranchoidea.
Hermaeidae is a taxonomic family of sacoglossan sea slugs. These are marine opisthobranch gastropod mollusks in the superfamily Plakobranchoidea.
Costasiella is a genus of sacoglossan sea slugs, a shell-less marine opisthobranchid gastropod mollusk in the family Costasiellidae.
Costasiella kuroshimae—also known as a "leaf slug", or "leaf sheep"—is a species of sacoglossan sea slug. Costasiella kuroshimae are shell-less marine opisthobranch gastropod mollusks in the family Costasiellidae. They range in size from 5 millimetres (0.20 in) to 1 centimetre (0.39 in) in length.
Ercolania is a genus of small sacoglossan sea slugs, shell-less marine opisthobranch gastropod mollusks in the family Limapontiidae.
Hermaea is a genus of sacoglossan sea slugs, a shell-less marine opisthobranch gastropod mollusks in the family Hermaeidae.
Limapontia capitata is a species of sacoglossan sea slug, a shell-less marine opisthobranch gastropod mollusk in the family Limapontiidae.
Calliopaea is a genus of sea slugs, marine gastropod mollusks in the family Limapontiidae. These are sacoglossan sea slugs.
