The Saltwater crocodile is the largest living reptile, and a truly fearsome beast. Growing up to 21 feet long, they are the undisputed masters of the waterways of Australia and Southeast Asia. They are apex predators, feeding on almost any living thing that they encounter. Despite the name, most saltwater crocodiles usually prefer freshwater, although young specimens have been known to travel in the ocean, being spotted as far north as the Sea of Japan. Saltwater crocodiles are not picky about what they eat, and have been known to attack humans. It is rumored that they might be responsible for more predatory attacks on humans than any other animal, rivaled perhaps only by the Nile crocodile. In 1945, during the Battle of Ramree Island, hordes of saltwater crocodiles are said to have killed 400 Japanese soldiers retreating through the swamps.
