The three-spot nudibranch, scientific name Aldisa trimaculata, is a species of sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Cadlinidae.

Distribution

This demersal species has so far only been found around the southern African coast, on both sides of the Cape Peninsula, in 10–30 m of water. It may possibly be endemic to that area.[1]
