About Nembrotha chamberlaini Gosliner & Behrens, 1997
Nembrotha chamberlaini is a nudibranch that is primarily white, with streaks of orange, yellow, green, or black across its upper mantle; the upper mantle occasionally also has yellow splashes. It has very distinctive bright red gills and rhinophores. Its foot and mouth parts are typically light purple. This species has a very characteristic color pattern that is typical of species that use warning coloration to communicate with other species. Nembrotha chamberlaini is easily confused with two other species: Nembrotha aurea and Nembrotha purpureolineata. All three species share a similar range of color variation, although N. aurea often has orange patches that are not present on Nembrotha chamberlaini. N. chamberlaini can grow to a maximum length of 100 mm. This species is only known to occur in the Philippines and Indonesia. Ecologically, Nembrotha chamberlaini feeds on ascidians, which are also called tunicates. It has been observed feeding on the bright-blue ascidian Rhopalaea sp, as well as the other ascidian species Clavelina sp. and Oxycorynia sp.
