The smooth-fronted caiman is a small crocodilian reptile found in and around the Amazon rain forest in South America. It is the second-smallest member of the Alligatoridae family in the world.

Male smooth-fronted caimans typically grow between 5 feet 7 inches and 7 feet 7 inches in length, while females rarely grow longer than 4 feet 7 inches. When a caimain is first born, it has a gold patch on the top of its head. Although the pattern disappears later, the smooth-fronted caiman is often referred to as the crowned caiman. The skin on the back of its neck and the top of its tail is made of a protective layer of scutes that are sharp, dense and triangular.
