Maximum size about 7 to 8 inches in body length.
Nearshore waters in areas of low salinity over organic-rich, mud bottoms. Juveniles usually inhabit seagrass beds and algal mats within estuaries.
Larvae feed on plankton (tiny floating plants and animals); juvenile and adult shrimp feed on detritus, plants, microorganisms, macroinvertebrates, and small fish. Cannibalism is also common among adults.
Spawning occurs April through October in nearshore waters. Sexually mature during first year of life.
