The largest land reptile is the saltwater crocodile (Crocodylus porosus). These formidable creatures can grow up to 23 feet in length and weigh over 2,200 pounds, making them the largest of all living reptiles. They inhabit brackish and freshwater environments across Southeast Asia, Australia, and various islands in the Pacific Ocean. Saltwater crocodiles are apex predators, feeding on a diverse diet that includes fish, birds, and mammals. Their impressive size, strength, and adaptability enable them to thrive in various habitats, while their swift movements both in water and on land make them highly effective hunters.
