Here's a photo of 2 Peltodoris nobilis, large and small, side by side. Surely they are not mating?

I love it when folks are up to speed on recent nomenclatural changes. My compliments to you. I know how much of a pain it is to stay current, but sea slug systematics is being refined all the time, and we should expect continued revision.
The revision changing Anisodoris to Peltodoris occurred in Valdes & Gosliner (2001). I mentioned this revision in my Supplement II to Pacific Coast Nudibranchs.
Now, concerning whether this pair is mating, es they could be. It is not uncommon to find young adults pairing with large individuals. Whether or not reciprocal fertilization is accomplished will depend on the sexual maturity of the smaller individual. But 1/2 inch should be large/old enough.
