The Polyceridae are a taxonomic family of sea slugs, dorid nudibranchs, marine gastropod mollusks within the superfamily Polyceroidea.
Hexabranchidae is a family of colourful nudibranchs which contains only a single genus, Hexabranchus, with six species.
Goniodorididae are a taxonomic family of sea slugs, specifically dorid nudibranchs, marine gastropod molluscs in the order Opisthobranchia.
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
Okenia is a genus of colorful sea slugs, specifically of dorid nudibranchs, marine gastropod mollusks in the family Goniodorididae.
Tritonia is a genus of sea slugs, nudibranchs, shell-less marine gastropod molluscs in the family Tritoniidae.
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.
