''Elysia pusilla'' is a species of small sea slug, a marine gastropod mollusk in the family Plakobranchidae. It is a sacoglossan. ''Elysia pusilla'' feeds on the calcified green alga ''Halimeda'' and incorporates functioning chloroplasts into its body, thus it is known as a solar-powered sea slug. It is found in shallow water in tropical regions of the Indo-Pacific wherever its host species grows. ==Description== ''Elysia pusilla'' is a cryptic sea slug which grows to about long. Its colour and shape both match that of the alga on which it is feeding; on older foliage it is flattened and a mottled pale green, on fresh new growth it is a brighter shade of green and on the cylindrical shoots that sometimes develop, it adopts a more circular cross section.〔(Elysiella pusilla ) The Sea Slug Forum.
