Re: Thuridilla picta from Cozumel, Mexico

Dear Bill,
I have been looking at the alga in Paul Osmond's photo, but I am not sure I can give a correct dentification. Of course I would like to say that it is a Derbesia sp. since that would fit my hypothesis of evolution of diets in the Sacoglossa perfectly. I guess it could be, but I have not seen any reference to that genus from the Caribbean. It could also be Caulerpa fastigiata, which would also be okay for my hypothesis, though not perfect.

It is nice to see that a Thuridilla can actually be found on a suitable alga. All the animals I have collected have been on bare sediment or dead corals.
Happy New Year,

Thanks Kathe,
Hopefully someone reading this will know an algologist who can help us with an identification
