Yacare Caiman

As this species of Caimans (caimans are closely related to alligators and found in South America) grow so does their lower jaw; there may be some caimans whose lower jaw may pass right through the upper jaw and protrude on top of the snout.
This species is considered 'not threatened' by IUCN, because they are found in plentiful in few areas, but the fact is, such ranges are diminishing and soon they may be found in too few pockets before IUCN updates its list.
So people better watch out and don't use any crocodile skin items.
