One of the most notable features of the mata mata turtle is, of course, its upper shell – or carapace. It is typically brown in color and covered in lumps, bumps and cones. But the turtle is often given further camouflage by the algae that clings to the creature. Underneath, the plastron is usually pink in juveniles, and it changes to brown or yellow as the species matures. Photo Credit: Farinosa/Getty Images
