Diamondback Terrapin

The diamondback terrapin (Malaclemys terrapin) is a turtle of brackish coastal marshes along the eastern and Gulf coasts of the United States, ranging from Cape Cod to the Florida Keys and around to Texas, with an additional population in Bermuda; it is the only species in its genus. Its shell carries a distinctive diamond-shaped pattern of growth rings on each scute, and its coloring and markings vary considerably between individuals. Females grow noticeably larger than males and use their strong jaws to crush the fish, crabs, snails, and mollusks that make up their diet. The species is assessed as Vulnerable by the IUCN and carries additional state-level protection in parts of its range, including endangered status in Rhode Island.
