Tylodina? from Monterey, CA

July 18, 2005
From: Clinton Bauder

Hi Bill,
This is a bit of a mystery. Not sure if these are even an opisthobranch but this site seems as good a place as any to ask the question, especially as it does at the very least resemble a Tylodina. These two pictures are of different animals. The first which is the shot of the top of the animal was taken about a month ago and is a larger (40mm+) than the second shot which is maybe 20 mm. After failing to ID the animal the first time we were looking for it again on Saturday. I didn't find it until right as we were calling the dive but we at least had time for a picture of the underside of the animal. The depth was about 20 meters on the shale beds off of Del Monte Beach. The photograph was taken by my friend Mike Jimenez.

Locality: Monterey, California, USA. Depth: 20 meters. Length: 20-40 mm.

Dear Clinton,
You have every right to be puzzled. The top photo looks a bit like a Tylodina but the colour doesn't seem right and I can't see enough detail in the animal to be very confident. Similarly with the underside. What I can see doesn't look right but I can't see enough to make another suggestion. The shape of the strange 'head tentacles' reminds me of the marine pulmonate Trimusculus but hopefully someone with local knowledge will be able to solve this painlessly
Best wishes,
Bill Rudman
