Caimans are reptiles that are closely related to their Central and South American neighbors, the alligators. Adult caimans are usually four to six feet (1.8 m) in length.

The caimans are found in South America, mainly in the Amazon basin, with one species extending into the southern part of Mexico and another reaching northern parts of Argentina.

Newly hatched caimans eat insects. Young caimans are eaten by Jabirus, Wood Storks, Great Egrets, and raccoons. Adult caimans have no predators except human poachers.
