The world has as many as 23 species of crocodile, stretching across the equatorial regions of both hemispheres. From the Florida Everglades in the United States to the Nile in Egypt, crocodiles live in the swampier, freshwater bodies of tropical regions where their most prized food source, fish, are easiest to be caught.
Crocodiles Dispersed around the Globe
Owing to their longevity as prehistoric creatures, the order Crocodylia is dispersed widely across the globe, with just one or two species in any one geographic location. The Nile region has its C. niloticus and C. cataphractus, for instance; Australia has its C. johnstoni (freshwater) and C. porosus (saltwater) crocs along the coastal regions; and the American Caribbean has its iconic American crocodile, C. acutus, but in Mexico and other parts of Latin America are more obscure species like C. moreletil and C. intermedius.
Crocodiles Live in Tropical Bodies of Water
One common denominator among all of these species and their native regions: geography. Crocodiles and their alligator cousins, which generally have rounded and not V-shaped snouts, live in tropical bodies of water, which tend to provide areas of vegetative cover near the shore. These shallower areas of rivers and lakes are prized by crocodiles for offering the best fishing, mating opportunities and nesting locations.
