The Polyceridae are a taxonomic family of sea slugs, dorid nudibranchs, marine gastropod mollusks within the superfamily Polyceroidea.
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
Nembrotha kubaryana, also known as the variable neon slug or the dusky nembrotha, is a species of colorful sea slug, a dorid nudibranch, a marine gastropod mollusk in the family Polyceridae.
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.
Polycera is a genus of sea slugs, specifically nudibranchs, shell-less marine gastropod molluscs in the family Polyceridae.
Halgerda is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae.
Tambja morosa, also known as Tambja kushimotoensis or gloomy nudibranch, is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the subfamily Nembrothinae within the family Polyceridae.
Nembrotha purpureolineata is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Polyceridae. Nembrotha rutilans, classified as a separate species until 2008, has now been reclassified as Nembrotha purpureolineata.
Roboastra is a genus of sea slugs, polycerid nudibranchs, marine gastropod molluscs in the family Polyceridae. They are carnivorous, feeding on other species of nudibranch.

Tyrannodoris is a genus of sea slugs, polycerid nudibranchs, marine gastropod molluscs in the family Polyceridae. Most of these species were formerly considered to belong to the genus Roboastra. They are carnivorous, feeding on other species of nudibranch, especially similar looking species of Tambja.
