Sea Slug recipes

Dr Rudman-
About the sea slug does indeed sound as if the posted recipe is for a holothurian, specifically because of the method of preparation- e.g. most slugs don't have a 'neck', etc. The addition of dirt is interesting, not just because it prevents boiling over, but it also could serve as some kind of absorbent for toxic compounds. (Holothurians have their share as well)
However, I have seen a reference to Tochuina tetraquetra(Dendronotacea)being eaten by Pacific natives (Behrens, 1991). I keep trying to find a recipe, but no one else seems to have heard of it.
Cheers- Brian
(PS- not really for posting, but because you said you were interested in who was responding.  I am a PhD student with Dr. Richard Palmer at University of Alberta, studying the evolution of feeding specificity in dorid nudibranchs. My background is in chemical ecology (insect/plant) interactions, and I became fascinated by nudibranchs partially because I suspect the same sort of interactions are occurring with them! Nicely done on the slug forum, btw. I especially like the backgorund photo of Glaucus)

Dear Brian, I hope you don't mind me posting your "details". Hopefully it will encourage others to follow suit. As you mention, I would like more participants to let us know something about them - not Monica Lewinsky detail - but enough to make replies and responses relevant. Some queries I get don't even indicate which part of the world they are from which makes relevant answers impossible. Thanks for the Dave Behrens reference to Tochuina. I'll see if he can give us details.

Your research field is very interesting to me as when I first started looking at colour in chromodorid nudibranchs in Tanzania it was to insects I turned for ideas. A colleague in Dar es Salaam, David Smith, was studying mimicry and population genetics in Danaid butterflies and their mimics / models such as Hypolimnas. He was working with leading researchers in the field such as Miriam Rothschild, and it didn't take much of an intuitive leap to realise my beasts were probably doing much the same thing. Its just so much easier with insects to test theories than with nudibranchs I'm afraid.

It would be good if you could send us some information or ideas on your work either as 'in progress' or when you finish.

Glad you like Glaucus. I had been thinking of posting some pics of Glaucus and Glaucilla. Perhaps your message will be catalyst enough.

best wishes
Bill Rudman.
