Onchidoris


Onchidoris is a genus of dorid nudibranchs in the family Onchidorididae. One of its members is known to prey on barnacles and the others eat bryozoans. The radula contains a rachidian tooth when fully developed, but this is vestigial in some species.A molecular phylogeny study showed that they aren't closely related to some other species of Knoutsodonta within which genus they were formerly placed.

Taxonomy

Many authors prefer Onchidorus Blainville, 1816 as the valid name for the genus, changed to Onchidoris. According to Pruvot-Fol however this latter is a nomen nudum, while the elder synonym Villiersia is a nomen oblitum. This is why Odhner, Pruvot-Fol, Swennen and Abbott are followed in the use of Lamellidoris Alder & Hancock, 1855.
