The yacare caiman is a crocodilian that is that inhabits a small area of South America including southern Brazil and Bolivia, Paraguay and northern Argentina. The species has a population of over 10 million individuals in the Pantanal tropical wetland. As a smaller than average crocodilian, the yacare caiman feeds mostly on smaller animals like fish, snails, crabs and birds. The species generally builds a mound nest and protects their eggs when the risk of human interaction is high. The largest risk to the yacare caiman population is illegal hunting for the animal's hide.
