Comment from Nathalie Yonow on photo #10284
With those huge oral tentacles and keeled tail. It is a major predator on other gymnodorids.Comment from Richard Willan on photo #1312
The body is smooth (pustulose in Gymnodoris okinawae), the apex of the rhinophores is vermilion (white in Gymnodoris okinawae), and this photo seems to show the gills forming a circle, so it is probably Gymnodoris alba. One would need to know the position of the genital aperture to be sure.Locality:
