The Mata Mata Turtle
One look at this turtle and you would believe that it was some kind of prehistoric dinosaur. You wouldn’t be that far off; turtles and tortoises are some of the oldest species to still exist from before humans were a thing. The mata mata turtle is a freshwater turtle that is found in the Amazon basins, and its appearance is mostly for camouflage reasons. You see, this turtle is only 18 inches long, which makes them prone to be eaten by bigger animals. If it remains still, it mimics the appearance of fallen leaves in the mud.
