I found this opisthobranch at Ishigaki-Island, Okinawa, Japan. July, 2000.
Lengths: 50mm, 40mm
These animals crawled at very high speed on the top of the overhang. When I touched one, it put out purple ink like a sea hare. Could you tell me what kind of opisthobranch is this?

I am pretty sure that this is a new species of Philinopsis (Family Aglajidae). Looking at the shape of the head I would guess that it has a long muscular pharynx like Philinopsis gardineri. The only other species of Philinopsis with a colour pattern of transverse lines is Philinopsis lineolata.
The purple ink you describe is unusual, as most aglajids produce a yellow ink, when they are disturbed, from a gland which opens into or near the anus. As you mention, Sea Hares are the only sea slugs I know that produce a purple ink.
This is a very interesting, and beautiful, new find

Is this a Chelidonura punctata?
