The Cuban crocodile is a medium-sized (usual maximum size of 3.5 m/11.5 ft, historical records of larger animals) critically endangered species endemic to Cuba and currently restricted to only two areas within the country (the Zapata Swamp on the Cuban mainland and the Lanier Swamp on Isla de Juventud). Evidence suggests that the species was also present within the Cayman Island and the Bahamas during historic times. The species prefers freshwater habitat (e.g. swamps) but may also tolerate saline habitat to some degree. The Cuban crocodile is surprisingly terrestrial for a crocodile and has adapted to hunting on land to some degree. In addition, the species is a well-documented "jumper" and may use this ability to catch arboreal prey species. The diet of adults includes fish, turtles and small mammals; during historic times the species may have preyed upon now-extinct giant ground sloths (hence the terrestrial adaptation). Cuban crocodiles have a notorious reputation in captivity as being aggressive and unpredictable, but only one fatal attack on human has been recorded in recent times (although it is possible others have gone unreported). The extremely restricted distribution of the species suggests that it is unlikely to come into contact with humans enough to be responsible for a high number of attack. Cuban crocodiles are currently threatened by the severe limitations of their distribution, hybridization with the sympatric American crocodile (jeopardizing genetic purity) and, on Isla de Juventud, competition with the introduced spectacled caiman.
