Saltwater crocodiles are the largest living reptiles, found in coastal regions and rivers across Southeast Asia, Australia, and the Pacific Islands. They can grow up to 23 feet long and weigh over 2,200 pounds. These powerful predators have a strong bite and are known for their ability to swim long distances in saltwater. These crocodiles are opportunistic feeders, preying on fish, birds, and mammals. They are highly territorial and can be aggressive, especially during mating season. Saltwater crocodiles play a crucial role in their ecosystems by helping to control populations of other species.
