Caimans inhabit Central, South America, and Australia. They are relatively small crocodilians, with the smallest being Cuvier's dwarf caiman (Paleosuchus palpebrosus), which grows to 1 m (3 ft) long, and the largest being the black caiman (Melanosuchus niger), which can grow to 4 m (13 ft) or more. Several extinct forms are known, including Purussaurus, a giant Miocene genus that grew to Script error: No such module "convert". and the equally large Mourasuchus, which had a wide duck-like snout.
