The name Crocodile came in Ancient Greece, and means 'lizard'. On external appearance, crocodiles resemble large aquatic lizards. However, Crocodiles, and other members of the family Crocodylidae are among the more biologically complex reptiles. Unlike most other reptiles, the Crocodiles possess a four-chambered heart, a feature mostly shown exclusively in birds and mammals. Other features include a diaphragm-like structure, again seen mostly in birds and mammals, and a cerebral cortex - the part of the brain mostly responsible for self-conciousness and the ability to learn. The crocodile, internally, is closer to that of a bird than to lizards, despite looking strikingly similar to other reptiles.

Members of the family Crocodylidae possess streamlined bodies and webbed feet, demonstrating its largely aquatic nature. However, most Crocodilians are also well adapted for terrestrial terrains. They can for example, run (or gallop) at speeds of up to 15 kph.

Crocodiles are commercially farmed in many places, for their leather, which is made into expensive shoes and handbags, and recently, in Australia, for their meat. In areas where Crocodiles are farmed, there is a strong incentive to protect the natural habitat in order to keep an effecient system where profit is sustained and the crocodile population and local food chains are unharmed.
