Aldisa smaragdina is a species of sea slug, a dorid nudibranch, a marine gastropod mollusk in the family Cadlinidae.[2]
This species was described from the Canary Islands. It has subsequently been reported from the Atlantic coast of Spain and from Portugal.[3]
This species has raised rounded tubercles covering the dorsum. There are two round markings on the back which are darker in colour. The animal grows to 30 mm in length.[3]
This nudibranch feeds on the hymedesmiid sponge Phorbas fictitius ( aka Anchinoe fictitius). The two darker round markings on the back of the animal closely resemble the inhalant pore sieves of Phorbas, providing excellent camouflage.[3] A progesterone homologue has been isolated from this species.[4]
