Acanthodoris hudsoni

Summary 4

Acanthodoris hudsoni is a species of sea slug, a dorid nudibranch, a shell-less marine opisthobranch gastropod mollusk in the family Onchidorididae. Its very long, tipped-back rhinophores and bristly papillae distinguish it from the similarly-colored Cadlina luteomarginata.

Diet 5

Acanthodoris hudsoni feeds on an erect ctenostome bryozoan of the genus Alcyonidium.

This species was described from Point Pinos, Monterey Bay, California. It has been reported from Alaska south to San Diego and Santa Catalina Island, California. A specimen from Asilomar, Monterey Bay has been sequenced for the 16S ribosomal RNA, Histone H3 and CO1 genes and several specimens from Puget Sound, Kitsap County, Washington have been sequenced for 16S and CO1.
