Re: Unusual sleeping behavior of Oxynoe olivacea

Dear Bill,
Some years ago, Cesar Megina told me that he observed a similar behaviour in aeolidaceans from the Strait of Gibraltar at night, such as Dondice banyulensis, Flabellina affinis andr F. ischitana. Thus, if you put the light of the torch in front of such nudibranchs, you could see that they were "sleeping". Then, after some minutes they started to move on the hydrozoans and to eat over them.
Regards.
Lucas.
