>>41795537The difference between the two existing types of snapping turtles, not species, is that one is a chaser while the other is a waiter. Common snapping turtles chase down their prey and bite down hard, while waiting snapping turtles use lures such as the alligator snapping turtle and its worm-like tongue. The longer the wait the hungrier they get so if they can catch something its good they have the bite force to snap through a human finger, although humans have the exact same bite force.
