The largest reptile on Earth is the saltwater crocodile (Crocodylus porosus). These formidable creatures inhabit brackish and freshwater habitats throughout Southeast Asia, the Indian subcontinent, and northern Australia. Males can grow over 23 feet (7 meters) in length and weigh more than 2,200 pounds (1,000 kilograms), making them the largest living reptiles. Saltwater crocodiles are apex predators, using their powerful jaws and swift agility to catch prey, including fish, birds, and mammals. Their ability to adapt to various environments, including rivers and coastal waters, has equipped them to thrive in diverse ecological niches, ensuring their survival over millions of years.
