Crocodiles – real predators. They are tearing their prey into pieces. Even if it is already a dead chicken. At least a five-meter crocodile Rex in Sydney at the zoo feeding behaves this way. A crocodile is any species belonging to the family Crocodylidae. The term can also be used more loosely to include all members of the order Crocodilia: i.e. the true crocodiles, the alligators and caimans and the gharials, includes prehistoric crocodile relatives and ancestors.
Rex weighs 700 kg. He was caught in northern Australia and placed in a zoo in Sydney in December 2009.
The teeth of a crocodile of the same type, conical, hollow inside – in these cavities as the depreciation of developing new teeth. Teeth for life crocodile changed repeatedly.
In this case the teeth of the upper and lower jaws are combined in such a way that against the very large teeth of one jaw are very small teeth of the second. Teeth are sitting in the alveoli, as in mammals.
On the development of the brain are higher than other crocodiles reptiles: the cerebral hemispheres have bark. Of the senses crocodiles are the most developed sight and hearing.
Most of the day crocodiles in the water. In the coastal shallows they go in the morning and late afternoon to take “sunbathing”.
They hunt crocodiles mostly at night. The main component of their diet is fish, but they also attack any prey, which can handle.
With the rapid movement of reptiles crocodiles only put his feet under the body (usually they are wide apart), some species can reach a speed of 17 km / h.
Voice of the crocodile – something between a bark and a roar, most often heard in the breeding season.
This crocodile, according to some estimates, 30 to 40 years.
Some of the largest species in between meals can take several months or even a whole year. Large mammals would not survive with such a diet.
