Rapana venosa
Rapana venosa is commonly known as the Veined Rapa Whelk. It is a large predatory gastropod native to the Northeast Pacific, from Russia to the Sea of Japan, Yellow Sea, and East China Sea. Introduced populations are known from the Black Sea, the Mediterranean, France, Argentina, and the Chesapeake Bay. Scattered specimens have been found in other locations including Washington, Spain and the UK. It is known from a wide range of habitats, including rocky shores, mussel beds, oyster reefs, sand, silt, eelgrass beds, and pilings. It preys on economically and ecologically important bivalves, such as clams, mussels, oysters, and scallops and has had negative impacts on bivalve communities in some locations.
