Snapping Turtle (Chelydra serpentina) Up-to-date distribution and status information can be found on the Montana Natural Heritage Program's TRACKER website at mtnhp.org. * Point observations outside of shaded native range are introduced animals/populations. Distribution/Taxonomy The Snapping Turtle {Chelydra serpentina) ranges along the Pacific Coast from Nova Scotia to Florida, and westerly to the Rocky Mountain front, from southeastern Manitoba to Texas and Mexico (Ernst et al. 1994). Two subspecies are recognized; the Florida Snapping Turtle (C. serpentina osceola) and the subspecies inhabiting Montana, the Eastern Snapping Turtle (C. serpentina serpentina) (Crother et al. 2008). In Montana, native populations are found from Carter County, east to Carbon and Stillwater counties, and northeasterly to McCone County. Most records are from the southeastern portion of the state in the Yellowstone River system and tributaries, especially along the Tongue River drainage. Currently, there are no confirmed Montana records from the Missouri River or its tributaries. Introduced populations exist in Flathead, Lake, Sanders, and Gallatin Counties (Maxell et al. 2003, MTNHP 2006). Maximum Elevation 1,158 m (3,800 ft) in Big Horn County (Maxell et al. 2003). Identification Juveniles and Adults: Snapping Turtles are large, stout turtles with an adult carapace length (CL) typically 20-35 cm (8-14 inches), but grow larger in populations of the southern United States (Degenhardt et al. 1996). Adults usually weigh 4.5-16 kilograms (10-35 lbs). However, one Montana individual found in the Redwater River reached 32 pounds (Aderhold 1980) and another Montana specimen reportedly reached 48 pounds (Werner et al. 2004). Snapping Turtles have a long tail about the 330. Please note that these images are extracted f
