Polyceridae
The family Polyceridae includes both nocturnal and diurnal species that often have elaborate tubercles or dorsal processes. They are specialized predators that eat bryozoans, tunicates, brittle stars or other nudibranchs. Some species in the genus Plocamopherus can swim by flexing their bodies latterly and are bioluminescent. There are at least 18 species known from Hawaii in eight genera (Crimora, Kalinga, Kaloplocamus, Plocamopherus, Polycera, Roboastra, Tambja and Thecacera).
