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.
