Of all regional crocodile species the Sea crocodile has killed and injured most of the human victims. It can measure 23,5 ft. When Sea crocodiles grow larger and larger the variety of animals of prey will also grow. Once it reaches a length of 16 ft. There is absolutely no reason why it shouldn't consider humans as animals of prey once they have crossed its territory, except for locations where men have hunted the Sea crocodile.
Sea crocodiles are also very mobile on the land, and, if necessary, they can cover long distances.
They are also capable of sprinting. Once in the water they are in their element. They will go into the water when they are disturbed or when they plan to hunt. This can sometimes be seen too in zoos. When a promising meal is approaching, e.g. a bird or a dog, a hungry crocodile which was dozing on a bank will quickly and silently slide into the water.
