The common snapping turtle (Chelydra serpentina) is a species of large freshwater turtle in the family Chelydridae.Its natural range extends from southeastern Canada, southwest to the edge of the Rocky Mountains, as far east as Nova Scotia and Florida.The three species of Chelydra and the larger alligator snapping turtles (genus Macrochelys) are the only extant chelydrids, a family now JD Kleopfer of the VA-DWR holds all that remains of a Virginia record Snapping Turtle ( Chelydra serpentina ). This specimen was caught at Ft. Pickett in August 2008 by a commercial snapping turtle fisherman. The turtle weighed in at 51 lbs. (23.13 kg) with a straight-line carapace length of 18 1/3 in. (46.5 cm). Phillips et al. (1996) proposed that three evolutionary species be recognized in the Chelydra serpentina group, but Sites and Crandall (1997) disputed their methods and conclusions and emphasized the need for further study using improved methods. In accordance with Phillips et al. (1996) and Shaffer et al. (2008), Crother (2012, 2017) and SNAPPING TURTLE ( Chelydra serpentina ): SPECIES ACCOUNT.
