Glossodoris sedna from the western Atlantic

November 5, 2002
From: Colin Redfern

Dear Bill,
As a footnote to Linda's record of Glossodoris sedna from Florida, there are two more references that clarify the known range of this species in the tropical western Atlantic. Bertsch (1988) examined two specimens from Tavernier Key, and referred to a photographic record from Key Largo, both of which are locations in the Florida Keys. He also referred to a photographic record from Biscayne Bay, Florida, but Lyons (1989) pointed out that the correct location for that record was in less than 1m of water at Green Turtle Cay, Abaco, Bahamas, which is approximately 200 miles north-east of Biscayne Bay. As far as I know, this is the only published record from a location east of the Gulf Stream.

• Lyons, W. G. 1989. Atlantic records of Glossodoris sedna (Gastropoda: Nudibranchia): A Correction. The Veliger, 32(4): 412.

Best Wishes,

Thanks Colin,
It would certainly be interesting to know if it has turned up anywhere else in the Caribbean region
Best wishes,
