Crangon septemspinosa

Crangon septemspinosa (sand shrimp), also known as seven-spined bay shrimp, is a species of shrimp commonly found along the Atlantic coast of North America, with a wide range spanning from Newfoundland to eastern Florida. Sand shrimp is often found in eelgrass beds, salt marshes, and estuaries and can be found at depths to 450 m (1,480 ft). At maturity, they can reach about 7 to 7.5 cm in length. Its name derives from the sand-like coloration that helps camouflage the species with its environment.
