7 Animals You Never Knew Existed

4. Matamata
These are tiny turtles found in South America. Matamata can go unnoticed when under water because their shells are like the barks of trees and their irregularly shaped heads resemble fallen leaves. This particular body shape and structure is utilized by the amphibians to catch their preys – fish and aquatic invertebrates – they simply stay still in stagnant pools or black water streams and wait as the water current bring unsuspecting preys their way. They then open their mouths and swallow their prey. They don’t chew because of the way their mouths are structured.
