Caimans usually sit at the top of the food chain in their environment, only to be hunted by jaguars and sometimes by anacondas. Jaguars are large cats that can fight caimans in and out of the water, while anacondas can hunt small caimans but usually lose to the large ones.
Caimans are related to alligators; however, caimans are typically, but not always, smaller than alligators. Common caimans grow 3 to 6 feet in length, but the largest species, the black caiman, can grow over 13 feet. They are mostly found in rivers and lakes of South and Central America's forests.
