Crocodiles live primarily in lowland, humid tropical regions across both the Northern and Southern hemispheres. Their habitats include freshwater rivers, lakes, marshes, swamps, and occasionally brackish or saltwater areas such as coastal regions and estuaries. Geographic Distribution:

• Africa: Most crocodiles, including the Nile crocodile, are found in sub-Saharan Africa, especially in eastern, southern, and central regions. They inhabit rivers, lakes, dams, and swamps, and can tolerate some brackish and marine environments

• Asia: Crocodiles live in India, Sri Lanka, Southeast Asia, including freshwater and coastal habitats. The gharial is found in northern India and surrounding countries

• Australia: Saltwater crocodiles inhabit northern Australia, living in coastal areas, freshwater rivers, and can even spend time at sea

• The Americas: The American crocodile lives in coastal areas of the Caribbean, southern Florida, Central and South America, favoring brackish or saltwater habitats such as mangrove swamps, ponds, and creeks

• Islands: Crocodiles are found on islands such as Madagascar, where the Nile crocodile has adapted to cave habitats, and in the West Indies

Habitats:

• Freshwater: rivers, lakes, marshes, dams, creeks, swamps
• Brackish and saltwater: coastal areas, mangrove swamps, lagoons, estuaries, beaches, and even open ocean for saltwater crocodiles

Saltwater crocodiles are especially adapted to coastal and marine environments but can also live in freshwater rivers

. American crocodiles prefer coastal brackish or saltwater zones but are sometimes found inland in freshwater areas

. In summary, crocodiles occupy a wide range of aquatic habitats in tropical and subtropical regions across Africa, Asia, Australia, and the Americas, thriving in both freshwater and saltwater environments depending on the species
