Conservation
Saltwater crocodiles are apex predators that play a critical role in coastal and river ecosystems by regulating prey populations and maintaining healthy food webs across mangroves, estuaries, and waterways. Once driven to near extinction by hunting for their skins, they now face ongoing threats from habitat loss, human–wildlife conflict, and coastal development. Conservation efforts—including legal protection, habitat management, regulated use, and education—have helped some populations recover while emphasizing coexistence between people and one of the world’s most powerful reptiles.​
