Range: Older records in Collins (1993) from Coffey County (KU 3017-20) are too imprecise to map, however, recent photographs turned in by Don Eccles lend support that this turtle may still exist there. Collins (1993) did not plot a 1912 record (USNM 55588) from Marion County and a 1925 record (KU 1918) from Stafford County.

Snapping Turtle Non-venomous

Alligator Snapping Turtle Non-venomous

Tennessee (TWRA): the alligator snapping turtle has a longer snout with a hooked beak, extra marginal scutes (shell-edge plates) and more conspicuous ridges on the shell. Missouri (MDC): its upper shell has 3 prominent ridges, one along the center line and one on either side, and its large head ends in a sharp, strongly hooked beak. Texas (TPWD): the common snapping turtle has an oval-shaped head and a comparatively smooth, rounded shell; the alligator snapper has three distinct ridges, a triangular head and a fleshy lure in its mouth. Caution: young common snapping turtles also have three keels on the shell (MDC, NCWRC, CT DEEP), so ridges alone do not separate small turtles.

Photos show typical adults; individuals vary. Never get close to compare.

When turtles are active in Kansas

Records of turtles in Kansas peak in May to July. They show when people record turtles, not how many there are (about month bars).
