From: Paul Sim
Hi Bill,
Please help ID this Triopha. Some people locally think it a variation of Triopha catalinae. I've only seen it twice but each time it has been a brownish base color. I include two individuals for your perusal.
Locality: Whytcliff Marine Park, British Columbia, Canada. Pacific Ocean.
Depth: 50 feet. Length: 1 inch. 06 October 2004. wall. Photographer: Paul Sim
Thanks,
Paul

Sim, P.D., 2005 (May 10) Brownish colour form of Triopha catalinae. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/13733Dear Paul,
I would agree that it looks rather different from Triopha catalinae. It is the animal called Triopha sp. 1 in Behrens, 1991. According to Behrens (2004) Sandra Milen has looked at its anatomy and decided it is a colour form of Triopha catalinae. Specimens of this colour form are noted by Behrens from Washington, British Columbia and Alaska
