Crocodiles (family Crocodylidae) or true crocodiles are large, semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia.The term “crocodile” is sometimes used more loosely to include all extant members of the order Crocodilia, which includes the alligators and caimans (both members of the family Alligatoridae), the gharial and false gharial (both ...

The American crocodile (Crocodylus acutus) is a species of crocodilian found in the Neotropics.It is the most widespread of the four extant species of crocodiles from the Americas, with populations present from South Florida, the Caribbean islands of Cuba, Jamaica, Hispaniola, [4] and the coasts of Mexico to as far south as Peru, Ecuador, Colombia, and Venezuela.
The black caiman (Melanosuchus niger) is a crocodilian reptile endemic to South America.With a maximum length of around 5 to 6 m (16 to 20 ft) and a mass of over 450 kg (1,000 lb), [6] it is the largest living species of the family Alligatoridae, and the third-largest crocodilian in the Neotropical realm.
Nearby adults, presumably the parents, may warn young of predators or alert them to the presence of food. The range and quantity of vocalisations vary between species. Alligators and caimans are the noisiest while some crocodile species are almost completely silent. In some crocodile species, individuals "roar" at others when they get too close.
Lake Turkana in Kenya has one of the largest undisturbed Nile crocodile populations. Generally, the adult male Nile crocodile is between 3.5 and 5 m (11 ft 6 in and 16 ft 5 in) in length and weighs 225 to 750 kg (496 to 1,653 lb). However, specimens exceeding 6.1 m (20 ft) in length and 1,000 kg (2,200 lb) in weight have been recorded.
Crocodiles (Crocodylidae) are a family of archosaur sauropsids. This family includes 14 species of large semi-aquatic reptiles that inhabit tropical areas of the world. Crocodiles tend to congregate in freshwater habitats, such as rivers, lakes, wetlands, and sometimes brackish water.
Large reptiles, or armoured reptiles such as turtles, were almost negligible in crocodiles under 2.5 m (8 ft 2 in) and most common in the stomachs of crocodiles over 3.5 m (11 ft 6 in) in length from Uganda and Zambia. Small species of reptiles are largely ignored as prey at this size.
