Images above of juvenile specimens were found by Dr. Paul Gainey who examined the wreck of a large speedboat that had drifted across the Atlantic semi-submerged. The vessel was originally found in December 1986 off St. Ives. This species is a non-native species from the south-east coast of the United States of America, Gulf of Mexico and Caribbean.
This is the species that was provisionally thought to be Atrina rigida in "Columbus and Pteria columbus", an article by Stella Turk MBE, in The Cochologists' Newsletter 105: 93-95.
Thanks to David Ehecatl Carroll and Chris Vos for their advice on the species.
