(Pease, 1871) [1]

Elysia rufescens is a species of sea slug, a marine gastropod mollusc in the family Plakobranchidae. This sea slug resembles a nudibranch but is not classified in that order of gastropods, instead belonging to a closely related clade, Sacoglossa, the "sap-sucking" sea slugs. This species was first described by Pease from Tahiti in 1871.

Description

Elysia rufescens is olive green with large white spots, often in a reticulated pattern, and grows to about 6 centimetres (2.4 in). The parapodia are somewhat convoluted and have dark blue edges and a submarginal orange line. The rhinophores are rolled and have blunt, greyish ends.[2][3]

Distribution

Elysia rufescens is found in the Pacific Ocean. Its range includes the coastlines of South Africa, Réunion, Thailand, Myanmar, the Philippines, Japan, Guam, Samoa, Tahiti, Hawaii and Australia.[3]

Biology

Elysia rufescens feeds on green filamentous algae such as Bryopsis pennata, which it rasps with each of a series of rachidian teeth.[3]
