Description
Chromodoris is the type genus of the family Chromodorididae: colourful nudibranchs of tropical and subtropical reefs, mainly in the Indian and Pacific Oceans, including the Red Sea (for example C. quadricolor). They feed on particular sponges and sequester their chemicals for defence. After a 2018 study the genus was narrowed to about 22 species, and many species formerly placed in it were transferred to Goniobranchus.
Identification
These are slugs with a thick mantle, sometimes bearing tubercles, and the characteristic species of the genus show black longitudinal lines on the mantle and a brightly coloured border. Feathery gills are arranged around the anus. Because the genus was narrowed in 2018, identifying new or older species requires checking the recent literature.
