Here's two of the fingerprint cyphomas (Cyphoma signatum) I found over the weekend. There were three close together however the third had been terminally damaged by something. These are the first of these I've found here and none of the dive guides I've spoken to have seen them here either.
Of course small animals like this could get moved a long way as eggs on debris so its not hard to understand why a group of three animals could spring up where we haven't previously seen them. Also with their mantle retracted these are almost identical to Flamingo's tongues so they'd be easy to overlook.
