The smallest species is the Cuvier's dwarf caiman (Paleosuchus palpebrosus), which grows to 1.2 to 1.5 m (3.9 to 4.9 ft) long. The gharial is critically endangered as a result of habitat loss, depletion of fish reserves, and entanglement in fishing nets. The jaw is designed to feed on a variety of prey.
