Thecacera pennigera laying eggs - Woods Hole

Bill -
I know you are always interested in photos of nudibranchs actually doing something. Here is a photo of Thecacera pennigera from Woods Hole, Massachusetts, laying eggs. At least that's what I assume was going on.
All the egg strands I found were white but from time to time I encountered some that were pinkish. I assume that the pink coloration indicates that they were newly laid and that they turn to the white color after a time. I could be wrong on that though.
Best wishes,

This is an interesting addition to your earlier messages on these animals from Woods Hole. The eggs of quite a few species show a colour change as they develop but I am not sure if those of Thecacera pennigera have been reported to do so.
Best wishes
