Crocodiles
are the largest reptiles in the world and the closest living relatives
of birds (!), with whom they share a lineage from the archosaurs.
The
saltwater crocodile is the most dangerous of all crocodiles. It holds
the record for the largest crocodile: It can weigh up to a ton, as much
as a small car. While most crocodiles live in rivers and lakes, the
saltwater crocodile is the only one that can deal with both fresh water
and saltwater of the seas. In addition to the saltwater crocodile, there
are many other kinds, a total of 25. These include, for example, the
Nile crocodile, the armoured crocodile, alligators and caimans.
