Dear Harriet,
This is almost certainly Cerberilla tanna. Have a look at the Fact Sheet and other attached messages. This is an interesting find as we know very little about this species and other species of Cerberilla from the Caribbean, Until we build up more information it is not possible to be sure just how variable in colour these species are. It would be nice to have some information on its size, if at all possible.

I have added a close-up of the head end to show the rows of cerata, and the brown digestive gland duct which runs up the centre of each ceras. I have arrowed the very short rhinophores, which are quite typical of the genus.
Best wishes,
Bill Rudman
