genus
Corbicula
“Asian Clam”
Genus Overview
The invasive, nonnative Asian clam tends to be larger size (to about 2 inches) and has prominent, raised, concentric ridges on its thick, tough shell. Young Asian clams might be confused with fingernail clams, but look for the raised ridges and thick shell. On older specimens, the brownish outer shell covering typically flakes off to show the white layer underneath.
Invasive species of Asian clam (Corbicula spp.), zebra "mussel" (Dreissena polymorpha), and quagga "mussel" (Dreissena bugensis) are nuisances for humans and native bivalves including native pea clams and fingernail clams.
