Crocodilians
There are officially 2 large species of Crocodilians and one introduced species found in Florida. They are the largest reptiles and the largest predators of the state. The Spectacled Caiman was introduced in the 1960s by pet traders who sold them privately as pets, but once the caiman matures they become aggressive towards their owners and would release them into the wild. These non-native species are found in four counties: palm beach, seminole, miami-dade, and broward. In these Southern Florida counties they are often found in or near urban areas. They are found in lakes and canals in the miami area and in swamps, but the caimans are also competing with Florida's native species.
