American Crocodile Habitat These crocodiles establish territories in large rivers or streams, swamps, lagoons, or estuaries. They can tolerate salt water, so they may also be found in salt marshes, freshwater marshes, mangroves, swamp forests, river mouths, and sometimes in the open ocean. The bodies of water in which they live are usually in lowland dry, moist, or wet forests. Range This species ranges from Mexico to Peru on the Pacific slope and to Colombia and northern Venezuela on the Atlantic side. Southern Florida and some Caribbean islands are also home to the American Crocodile. In Costa Rica it lives in the lowlands along both coasts but is mostly restricted to national parks. National Parks Corcovado National Park, Santa Rosa National Park, Carara National Park, Tortuguero, CaƱas, Taboga, and on the Tarcoles river near the Pacific coast. Physical Description The only other crocodilian in Costa Rica is the Spectacled Caiman; the crocodile is considerably larger and has several other distinguishing features. The American Crocodile’s head is more narrow and elongate with a skinnier snout, and the fourth tooth on both sides of the lower jaw is visible when its long mouth is closed. The croc also lacks the bony ridge that the caiman has in front of its eyes. This croc is different from other crocodiles in the Americas because the adult has a smooth bump or wart in front of each eye. Its body can be shaded from green to olive or grey with dark crossbands on its back
