Siphonaria naufragum

Siphonaria naufragum is a species of air-breathing sea snail, or false limpet, a marine heterobranch gastropod mollusc in the family Siphonariidae.

Distribution

It is found in intertidal zones of rocky shores within Florida, the Florida Keys, and the Gulf of Mexico.

Taxonomic status

Siphonaria naufragum was initially thought to be a widespread species with an amphiatlantic distribution, Siphonaria ''pectinata. A 2015 molecular study clearly distinguished three lineages with no apparent connectivity. These lineages are now treated as three separate species. The S. pectinata is restricted to the eastern Atlantic and Mediterranean, S. naufragum from Florida and the Gulf of Mexico, and S. placentula'' Menke, 1853 from the Cape Verde Archipelago.
