These crabs, often referred to as the Chesapeake blue crab or the Atlantic blue crab, are excellent swimmers, partly because of their fifth set of legs, designed like paddles. With their frequently brilliant blue claws and olive-colored carapace, they are striking to notice (shell). The adult female blue crab has red tips on her claws. The size of females is slightly less than that of males, who may reach seven to eight inches (18 to 20 cm) wide.
Blue crabs could be found in saline lagoons and estuaries south of Uruguay from Nova Scotia through the Gulf of Mexico. The Chesapeake Bay's frigid waters and unique environment offer the best circumstances, supporting the largest crabs, and home to the largest crabs.
