Ischadium recurvum, known as the "hooked mussel" or "bent mussel," is a species of bivalve mollusc in the family Mytilidae. It can be found along the Atlantic coast of North America, ranging from Cape Cod to the West Indies.[1] They are often found growing on Eastern oysters, either intertidal (south of Chesapeake Bay, where the exposed oysters can survive the winter) or subtidal.[2] They also attach to other hard substrates, including artificial reefs[3] and dead shells of brackish water clams, Rangia cuneata.[4]
