Eastern Box Turtle

Although most turtles can withdraw into their shells, a box turtle can close up more completely than other species.   That's because its plastron, or lower shell, is hinged, and the front and rear sections can be bent upward so that the edges of the two shells meet.  Box turtles are basically land-dwelling reptiles, but sometimes cool themselves in woodland pools or puddles.  They are renowned for their longevity.
