True crocodile
* Info taken from Wikipedia and edited slightly.
The saltwater or estuarine crocodile (Crocodylus porosus) is the largest of all living reptiles. They are normally found in Northern Australia, on the eastern coast of India and in parts of Southeast Asia.
An adult male can weight between 1,300–2,200 lb and be between 13-18 feet long although longer specimens have been recorded. Females are significantly smaller tending to be in the 7-11 foot range due to a high level of sexual dimorphism in the species.
Saltwater crocodiles are the Apex predator in their home range ( though susceptible to predation as babies and juveniles) and prey on practically everything else. This includes monkeys, kangaroos, wild boar, dingos, goannas, birds, domestic livestock, pets, humans, water buffalo, gaurs, bats, and even sharks. They hunt mostly at night and wait until their prey is within striking distance before launching themselves at it. Crocodiles are most famous for the technique known as the "death roll" where they grab onto an animal and roll powerfully. This throws any struggling large animal off balance, making it easier to drag it into the water. The "death roll" is also used for tearing apart large animals once they are dead.
Other interesting facts
* A 6-meter-long crocodile can lie completely invisible in less than a foot of muddy water.
* Large crocodiles have the strongest biting force of any animal alive- exceeding 5000 psi.
* Crocodiles can slow their metabolism to such an extent that a tree with an intruder hiding in its branches may be guarded continuously for several weeks, without breaks for food.
* Crocodiles have strong muscles for closing their jaws and holding them shut, but weak muscles for opening them.
* Unlike other reptiles, they have a cerebral cortex; a four-chambered heart; and the functional equivalent of a diaphragm.
