Hi,
I am a graduate in biology from Universidade Federal do Espirito Santo and a PADI Instructor. I'm sending some pictures I took at Rasas island, Guarapari - SE Brazil. I couldn't find this animal in topics related to Brazil or either if it's registered to this region.
I hope that it helped some one.

Locality: Rasas island, Guarapari, Espirito Santo, Brazil. Depth: 14 -15 m. Length: About 20 mm.13 March 2005. Rocky botton near to the edge of island's wall and sand botton. Photographer: Ivan Pierozzi Jr

Best regards,
Ivan Pierozzi Jr.

Dear Ivan,
This is an interesting find. In colour it looks very similar to Greilada elegans from the northeastern Atlantic, but there are quite significant differences in shape which suggest it is not that spepcies. For one there is no trace of a ridge around the mantle edge, and instead of having multiple small papillae around the anterior mantle edge, there is a wide swelling alongside each rhinophore. If you have other photos which show the head I would be interested in seeing them.

Your animal is a polycerid but without some information on its anatomy, it's a bit hard to say much more. Whatever it is, it is a spectacular colour, and is probably a new species.
Best wishes,
Bill Rudman
