The Cuban crocodile is of interest to biologists for its unique physical and behavioral traits. Long- and strong-legged, it is the most terrestrial of extant crocodiles. Its preferred habitat comprises freshwater environments such as marshes and rivers. There, the adults feed on fish, turtles and small mammals, while the young eat invertebrates and smaller fish. Mating occurs between May and July. Captive animals have displayed cooperative hunting behavior and could be taught tricks.
The Cuban crocodile is listed as Critically Endangered by the International Union for Conservation of Nature. Once spread across the Caribbean, its range has dwindled to including only the Zapata Swamp and the Isle of Youth, due to hunting by humans. Captive breeding projects are in place to help the species recover.
