The cephalic tentacles have many fine annular creases and other creases roughening the surface, most pronouncedly when the tentacles are contracted. A large black eye is set into the slightly expanded, truncated end of an eye-tentacle that is fused for its entire length to the distal face and ventral base (1) of each cephalic tentacle.
