Crocodylus porosus, commonly known as the saltwater crocodile, is the largest living reptile, found in coastal regions and rivers across Southeast Asia, Australia, and the Pacific Islands. They can grow up to 23 feet (7 meters) in length and weigh over 2,200 pounds (1,000 kg). These crocodiles are known for their powerful jaws and adaptability to various habitats, including brackish and freshwater environments. Saltwater crocodiles are carnivorous and primarily feed on fish, birds, and mammals. They are excellent swimmers and can travel long distances in the ocean. Their strong territorial instincts make them formidable predators, and they play a crucial role in maintaining the balance of their ecosystems.
