Biology & Habitat

Appearance

At maturity, Eastern oysters can reach up to 8 inches. The shell has smooth edges and is oval with a "cupped" shape, giving rise to its alternate name "American cupped oyster." The inside of the shell is white to off-white to brownish in color.

Biology

Eastern oysters are of the shellfish family. Like mussels, clams and scallops they are bivalve mollusks, and have a hinged shell. They have fast growth rates and high reproduction rates. Each female Eastern oyster can product over 100 million eggs during one spawning event. Adult Eastern oysters are sessile—they stay in one place—and inhabit both intertidal and subtidal areas.

Where They Live

Range Eastern oysters are found along eastern North America from the Gulf of St. Lawrence to the Gulf of America (formerly Gulf of Mexico). They are found in the middle and lower Chesapeake Bay and its rivers. They are the only species of oyster native to this region. Habitat Eastern oysters live in brackish and salty waters from 8 to 35 feet deep. In some warmer areas, they are able to live in the intertidal zone.
