Aldisa cooperi is a species of sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Cadlinidae.
This demersal nudibranch is found in cold-temperate waters from the intertidal to subtidal zones (up to a depth of 20 m) along the Pacific coast of North America, from the California to Alaska. It has also been reported along the coast of Japan and Korea. It is preferably nestled in its food sponge Anthoarcuata graciae.[2]
Cooper's aldisa is a small dorid nudibranch, growing to a length of 2.5 cm. Its mantle has a yellow to orange color with some black spots spread over it. It has a smooth body covered with sparse, low tubercles and gills clustered on its rear side. It lays its eggs in ribbons.
Its vulnerability is low to moderate, but it is not listed in the IUCN Red List.
