Could you please identify this nudibranch for me.
I believe it is some form of Okenia possibly Okenia zoobotryon.

This is Okenia mija. These little brown species of Okenia are difficult to identify but the little brown spots usually have a translucent ring around them in this species. We don't know a lot about the biology of these species but I suspect we will find that many of them feed on particular bryozoans. I have found this one feeding on Amathia wilsoni, and although it may be wishful thinking, I think the bryozoan in your photo is Amathia.
