Smooth rhinophores and oral tentacles are translucent white, sometimes tinted yellowish (3) to reddish (4), with opaque white (1) or yellow (2) pigment distally. Black eyes clearly visible from above at the posterior base of the rhinophores (3), unless hidden by tilt of rhinophores (4).
Oral tentacles originate above the ventrally slit, outer lips of the mouth.
