Taxonomic Group: Mollusks-Gastropods


Busycotypus canaliculatus is a large predatory snail commonly known as the Channeled Whelk. It is native to the Eastern coast of North America from Cape Cod, Massachusetts to St. Augustine, Florida. It is introduced and established in San Francisco Bay, California. It occurs in a variety of habitats, including oyster beds, mud, and sand flats from the intertidal zone to depths of about 15 m. In its native habitat, it is an important fisheries species and an important predator of bivalves, but there is little information on its economic or ecological impacts in its introduced range.
