The Saltwater Crocodile (Crocodylus porosus) 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 strong swimming abilities, making them effective predators. Saltwater crocodiles are opportunistic feeders, preying on fish, birds, and mammals. They are highly territorial and can be aggressive, especially during mating season. Their ability to tolerate saltwater allows them to inhabit a wide range of environments, from estuaries to open ocean waters.
