1. Alligator Snapping Turtle
Weird, isn’t it? This is one of the heaviest freshwater turtles worldwide – and one of the most powerful too! With a bite force of 158 kgf, the Alligator Snapping Turtle is surely something you don’t want to annoy. Thanks to its really strange appearance (which is used as a defense mechanism), it’s also known as the ‘dinosaur of the turtle world.’ Chances are you may not even see it because it lets algae grow on its shell and simply hides in the water.
