Dear Mike,
This is the black form of Phestilla melanobrachia. It is obviously been in an altercation with something because each black dot represents a lost ceras, or to be more positive, each black dot represents the bud of a new cerata. Like Phyllodesmium, species of Phestilla lack cnidosacs, the nematocysts of the corals they eat, obviously not up to the job of defending a nudibranch from predators. As you will see on the autotomy page, species of both these unrelated genera use their ability to drop off cerata as a defensive strategy, just like some lizards can drop their tails.
Best wishes,
Bill Rudman
