Stramonita canaliculata
Taxonomic Group: Mollusks-Gastropods


Stramonita canaliculata is commonly known as the Channeled Rock Shell. Its native range is uncertain, due to confusion with the congeneric species S. floridana. It was originally believed to be confined to the Gulf of Mexico, but native populations may overlap those of S. floridana along the Southeastern Atlantic coast of the US. The northern limit of both species is believed to be Cape Hatteras, North Carolina. Therefore populations found in Virginia are thought to be introduced and molecular evidence suggests that these specimens are S. canaliculata. This species inhabits rocky shores and oyster beds in shallow estuarine waters. It is a large predatory snail and is regarded as a serious oyster predator, but impacts on Crassostrea virginica (the Eastern Oyster) are unknown.
