Tridachia crispata

This is the only type of Sea slug I have seen in Curacao in three years. It does come in 3 or 4 color phases.
I am sure if I see another nudibranch, I will have a fisheye lens set up.

Wow, that is beautiful.. you may have only 1 in Curacao, but it's a beauty!

There must be others here, I just can't find them.
These are great subjects for macro and super macro. I search now for interaction between two or more sea slugs but haven't got an image yet that I really like.

Awesome shot. I love the blue ones. On page 141 of my Nudibranch Behavior book I show all four color variations in an attempt to educate all on the wide variation seen in many species.

Hey Dave, what's your opinion on crispata & clarki? Do you agree that they're separate & valid or really just variants of the same thing?

[smb2]

Here is the "Disco" version of crispata.
