Is this Navanax?
December 28, 2004
From: Peter McGuinness
I photographed these two slugs earlier this year at La Jolla Shores, California. I think they are Navanax (enjoying a little hermaphroditic coupling) but I have not seen this exact coloring in any photos I have been able to find. Do you have any further information?
Locality: La Jolla Shores (Marine Room)
Depth: 60 ft
San Diego County, California, USA
Length: 4 inches

McGuinness, P., 2004 (Dec 28) Is this Navanax?. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/12838Dear Peter,
Yes this is Navanax inermis. It is quite variable in colour, and only one species is known from California. I think the white triangular object you can see at the back of the right animal is its gill, which is usually hidden beneath the mantle shield which encloses the fragile internal shell.
Best wishes,
Bill Rudman
