Dear Dr. Rudman,
I believe these are Aeolidiella oliviae, along with a likely egg ribbon, flat worms, tube worm, et al. The orange color in the background is due to rust - the Branchs were found under an iron flake from a wreck.

Thanks for sharing this. Your shots really show the characteristics of this species well. In Bill's cropped close-up you can even see the spots locating the evolving eyes of this mollusk. It is also so nice to have the egg ribbon right there. Notice that this species lays an egg coil attached to the substrate on edge, rather than flat like other species.
