Range and Habitat
Range from Nova Scotia south to the Gulf of Mexico and the eastern shore of Central America. Predominant in inshore waters in spring and summer. Larvae move from offshore waters into estuaries. Juveniles live in marsh edge habitat, flooded grasses, and aquatic vegetation in upper estuaries. Move into deeper water and become more bottom oriented as they grow. Juveniles and adults are found over soft mud bottoms with lots of decaying vegetation.
Extremely abundant, fast-growing, and short-lived. Mate and spawn offshore while the female's shell is still soft after molting. Peak spawning is in the spring and summer. Eggs hatch offshore. Currents transport larvae inshore to estuarine nursery areas. Larvae eat plankton by filter-feeding and later feed on decaying organic matter. Juveniles are omnivorous, eating microorganisms, plants, and small invertebrates. Adults are more predatory, feeding on insect larvae and larger marine invertebrates.
