Doris odhneri (MacFarland, 1966)

Previously assigned to the genus Archidoris , this is one of the largest cryptobranch dorid on the California coast. Specimens may reach up to 200 mm in length. The animal is pure white, with no marking what so ever. The notal surface is covered with large rounded tubercles. Some specimens in Puget Sound and Canada have a yellow cast. This species is a sponge eater, feeding on Halichondria, Craniella, Hymeniacidon, Lissodendoryx, Mycale and Stylissa. It ranges from the Bering Sea to San Diego, California. Juveniles might be confused with Aldisa tara and other white dorids.
