Dear Dr. Rudman,
I came across this specimen while diving in the Guanacaste region on the Pacific Coast of Costa Rica. I just recently discovered the Sea Slug Forum and have found it to be very help and informative.
Locality: Playa del Carmen, 10-15m, Guanacaste, Costa Rica, Pacific Ocean, 26 March 2007, Rocky reef. Length: less than 1 inch. Photographer: Russel Schoenhard.
Thanks in advance for your help.

Schoenhard, R., 2007 (Jun 22) Glossodoris sedna from Costa Rica. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/20006Dear Russel,
This is Glossodoris sedna. It was first found on the Pacific Coast of tropical America and now has been found in parts of the Caribbean. This poses the interesting question of whether this species was a Pacific coast animal which has been moved to the Caribbean by human intervention, perhaps as ballast water in shipping, or whether it is one of those species which occupied both regions before the Panama Isthmus was formed.
Best wishes,
Bill Rudman
