Hello all, Can someone help me with a Nudibranch ID? At first glance, I thought this was common. However, I looked back through my photos and in several books and couldn't find anything to match.
I think your right. That’s what an expert mentioned late last night in an email to me. Also called a Catriona columbiana. And it was very small. I’ve probably seen one before, but did not recognize it as something different.
