Similar looking animals have been reported from Australia and India.[3] DescriptionThis Okenia has a broad body and many short, triangular, pointed, lateral papillae. There are scattered, shorter, papillae on the back, between the rhinophores and the gills and in front of the rhinophores. The body is described as uniformly brown with small spots of white pigment. Recent finds from Japan show body colour is variable through red to orange and the papillae have orange tips.[3] EcologyThe diet of this species is probably a ctenostome bryozoan.[4] References1. ^Baba, K., 1949.
