Species Account:

        I've not personally seen Thordisa villosa here in the waters of Okinawa's main island. Atsushi Ono mentions collecting only a single specimen (pers. comm.) but has seen several individuals in the Keramas* and considers this animal to be very rare there. Atsushi reports finding the above featured animal on the under side of dead coral. For additional information concerning this dorid, Bill Rudman has a series of messages and images of T. villosa posted on the Sea Slug Forum.

        In addition to the above featured animal, I've previously presented on these pages the following members of the genus from Okinawan waters:
