More photos of Anisodoris lentiginosa

Hi Bill,

So I'm even more confused now! Two things which I forgot to mention about my British Columbia critter; first it was large - maybe 180 to 200mm long. Second, the pigment on the spot on the back does not appear to extend onto the tubercle protruding from the middle of it. Hopefully these are useful clues. The size would seem to eliminate Geitodoris heathi but not Anisodoris lentignosa. I hadn't considered the latter as the picture in Dave's book doesn't look anything like my critter but the description seems to indicate that Jeff might be right. Also the fact that the tubercle lacks pigment weighs against Archidoris montereyensis.

I've enclosed 2 more images from my video more clearly showing the size and the spot on the back.

Dear Clinton,
Sorry it's taken a while to answer your message but I thought it was best to try and get the identity right before I posted any more 'sea lemon' pictures. Thankfully Sandra Millen has clarified things for me. If you have a look at her message you will see she is pretty sure your animal is a colour form of Anisodoris lentiginosa.

If you look carefully at your lower photo, you can see faint darker patches which I guess represent the dark patches in more typical animals.

And for those of you unfamiliar with the fauna, the red-orange animal on the right in the top photo is not a sea-lemon. It is the tritoniid Tochuina tetraquetra.

Sandra also suggests the upper right photo in your original message is of a white and yellow Geitodoris heathi rather than Archidoris montereyensis.

Best wishes,
Bill Rudman.
