I have read with much interest recent messages regarding color variation in various nudibranchs as well as in their egg masses.
On Sept. 3rd, you answered Betsey Hansen's question about egg color by saying that egg masses change color as the embryo develops ... that observation certainly supports my own impressions and much of what I have read for ascoglossans or sacoglossans.
As an experimental ecologist, however, I was wondering if anyone has actually explicitly demonstrated ontogenetic changes in color and/or diet-associated colors of egg masses? If anyone in the forum is aware of experimental studies on this topic, I would welcome hearing about them.
Thanks in advance!
Thanks for the message and the material for the Participants List which I have added.
