Cerberilla tanna? from Florida

Dear Jeff,
This is a very interesting find. I only know of one speies of Cerberilla being reported from the Caribbean region and that is Cerberilla tanna. Unfortunately, like many of the species described by the Marcuses, it was desribed from a preserved specimen so we have no information on its living colour. Anatomically species of Cerberilla are quite similar to each other, bbut it might be poossible to match their description of the shape of the radular teeth. Your animal has a very impressive colour pattern. Species of Cerberilla are probably much more common than we think, but because they spend most of their time buried in soft sediments, such as sand, we don't often see them. I guess we can call your animal Cerberilla cf. tanna until the radula of a known live animal an be matched with the original description.

It is possible that Linda Ianello's animal from the same location is a juvenile, but we would need an animal intermediate in colour before we could confidently say so. My copy of Paul Humann's book doesn't have a Cerberilla in it, so I would be interested to know what he says, and what his animal looks like. Thanks again for a very interesting find.
Best wishes,
Bill Rudman
