All vertebrate animals, including crocodiles, have jaws with the same movement. The skull is joined to the spine and the bottom jaw moves on a hinge to open and close the mouth. The size of a crocodile depends not only on age, but genetic and environmental factors. Some crocodile environments may have more food available and a more favourable climate than others. Charlie is one of our oldest crocodiles at Hartley's Creek but is certainly not the biggest.
Crocodiles have little stubby legs and because they are reptiles, they have limited endurance.
Large crocodiles, like Charlie can only run at about 10 kilometres per hour, for a very short distance. At Hartley's Creek we believe crocodiles are the same as most animals and prefer to eat fresh food, but when they are hungry and cannot catch fresh food, they will eat carrion. The question of whether crocodiles actually store their food is more difficult to answer. A bloated carcass floating down a river can become wedged in a snag by the wind or tide. The rotting meat attracts crabs and turtles, which they love to eat.
