The largest type of reptile is the saltwater crocodile (Crocodylus porosus). Adult males can reach lengths exceeding 20 feet (6 meters) and can weigh over 2,200 pounds (1,000 kilograms), making them the largest living reptile in the world. Saltwater crocodiles are found in a range of habitats, including brackish and freshwater environments, and they have a wide distribution, primarily in Southeast Asia, northern Australia, and parts of the Indian subcontinent. They are known for their powerful jaws and aggressive behavior, making them formidable apex predators in their habitats.
