Crocodiles primarily inhabit freshwater and brackish environments, such as rivers, lakes, swamps, and mangroves. They can also be found in coastal areas and estuaries. These reptiles prefer warm climates, as they are ectothermic and rely on external heat sources to regulate their body temperature. Crocodiles are well-adapted to their habitats, featuring powerful jaws, webbed feet, and tough skin, which allow them to thrive in both aquatic and terrestrial environments. They are skilled predators, often ambushing their prey from the water's edge or lying in wait submerged in water.
