Mexichromis pusilla is a species of sea slug or dorid nudibranch, a marine gastropod mollusk in the family Chromodorididae.[2]

Distribution

This nudibranch is found in the tropical Indo-Pacific Ocean.[1]

Description

Mexichromis pusilla has a pink-orange body, gills and rhinophores. The mantle is edged with a thick pale yellow band, and there are two white spots on its dorsum. This species is easily confused with other similarly coloured nudibranchs, especially Noumea varians and Noumea norba.[1]

This species can reach a total length of at least 20 mm,[1] and like all Chromodorids, feeds on sponges.[3]
