Crocodiles live in still and shallow waterways, such as rivers or swamps, in tropical climates throughout Asia, Africa, Australia and the Americas. Some species of crocodile prefer saltwater habitats, while others prefer freshwater.
American and Morelet's crocodiles, which are both found in the Caribbean regions of North and Central America, can be found mostly in rivers and swamps in both saltwater and freshwater. American crocodiles can be found as far north as south Florida.
African crocodiles, such as the slender-snouted crocodile and Nile crocodile, tend to prefer protected rivers, mangrove swamps and freshwater marshes. The Nile crocodile is also found in sub-Saharan Africa and Madagascar.
