Description:  Concentric ridges on the carpace and dark spots or streaks on the skin of the Diamondback Terrapin are its most distinguishable characteristics.  Females are usually considerably larger than males. 
Habitat:  Primarily inhabits coastal marshes.  It can tolerate fresh water, but rarely leaves salt or brackish water.
Range:  Found along the entire eastern seaboard.
Diet:  Fish, crustaceans, mollusks, and insects.
Status:  Considered a special concern species by the state of North Carolina and listed as a threatened species by the World Conservation Union.  Hunting of Diamondback Terrapins for their flesh severely depleted many coastal populations, but recent conservation efforts have contributed to its comeback in certain areas.
