Distribution
This demersal nudibranch is found in cold to temperate waters, from the intertidal to subtidal zones (up to a depth of 20 m), along the Pacific coast of North America, from California to Alaska. It has also been reported from the coasts of Japan and Korea.[4]
Description
Conservation status
The vulnerability of this species is low to moderate, but it is not listed in the IUCN Red List.
Ecology
It is usually found nestled in its food sponge Anthoarcuata graciae.[7] This sponge is currently classified as a member of the genus Antho, family Clathriidae, but may actually belong to the family Hymedesmiidae as other Aldisa species specialise on sponges from this family. [8]
