I am pretty sure this is a Varadero Doto (Doto varaderoensis) nudibranch. They are fairly small – only getting to a maximum of 1/2″ long – and they feed on hydroids (the things that kind of look like weird shaped umbrellas here). I’m not sure if the eggs in the second photo are from the Doto or just a coincidence.
