8. Alligator Snapping Turtle (1,000 psi)
If you ever went freshwater swimming as a kid, you might have had a friend or a sibling who teased you about dangerous snapping turtles waiting to bite off your fingers and toes. If we’re talking about the common snapping turtle, which are fairly docile and harmless, you probably had nothing to worry about. But if you happened upon an alligator snapping turtle, you might actually have been in danger of losing a digit or two. Though it is the smallest animal on this list, the alligator snapping turtle’s bite packs enough of a punch to slice through finger bones with ease. Granted, that kind of trauma is very rare because these turtles are uncommon and not particularly aggressive, but amputated fingers are not completely unheard of. Plus, alligator snapping turtles can live to be around 100 years old, and you know how cranky the elderly can be sometimes. Just watch where you step the next time you take a dip in the creek.
