Goniodoris felis Baba, 1949

Members of the family Goniodorididae H. Adams & A. Adams, 1854 are very different from polycerids, which they are usually listed with. Species in this genus have a wide foot and a prominent notal margin. The radular morphology and presence of a buccal pump suggests that these dorids are more closely related to the Onchidorididae than to polycerids. Both the Onchidorididae and the Goniodorididae are more closely related to cryptobranch dorids than to other phanerobranch dorid nudibranchs.

Goniodoris felis was described from Japan, but since its description it has been observed throughout the Western Pacific Ocean. The head and body are white. The prominent noral margin has a series of short tubercles. Its semi-transparent body with brown patches on the dorsum and hyponotum make this species very cryptic on the colonial tunicates it feeds on. Sometimes, finding the egg masses is the clue to finding the adults.
