Alright the alligator snapping turtle is the next animal I want to go over, mainly because I was studying one yesterday and it got scared and bit me XD. The alligator snapping turtle is the biggest freshwater turtle in the world.
Unlike common snapping turtles who have smooth shells, alligator snapping turtles have 3 large ridges on their shells and rugged head and necks that gives the a more prehistoric look.
The Thing the IJ was talking about is the awesome way they eat, the have a pink tounge that they wiggle like a worm, and they're mouths are grey and black, so combine that with the rugged look and the fact that they sit on the bottom of swamps they're prey follows their tounge straight into their mouths.

fun facts- alligator snapping turtles can weigh over 200 pounds, they can live up to 120 years. Oh and they can snap down on your fingers and chop them off, so keep your fingers away from their mouths >_>.
