Who are lizards? Detailed answer Directory / Big encyclopedia. Questions for quiz and self-education Did you know? Who are lizards? Lizards belong to the class of reptiles, or reptiles, which also includes crocodiles, turtles, and snakes. There are about three thousand species of lizards. A typical lizard has four legs, a short body and a long tail. All lizards change their scaly skin several times a year. They live in all parts of the world, except for the polar regions. Tropical zones are most favorable for them, but they can also live in regions with a temperate climate. Here in winter the lizards hibernate. Most lizards are small: they usually do not reach half a meter in length. The largest lizards are monitor lizards of Komodo Island in Indonesia, which can reach three meters in length and weigh about one hundred and forty kilograms. They are very reminiscent of mythical dragons from fairy tales. As a rule, lizards do not live long. Some live only two or three years. The record lifespan for a lizard in captivity is twenty-five years. Most lizards feed on insects, catching them with their long tongue right in the air. They usually swallow their prey whole. Although lizards have teeth and use them to hold their prey, they rarely use them to bite or chew it. Some lizards have a very specific "diet". For example, horned lizards usually feed on ants. Other lizards eat grass or only fruits. Large monitor lizards are one of the few carnivorous lizards. They feed on carrion, and sometimes they catch small wild pigs, which they swallow whole. Most species of lizards hatch from eggs, but there are some that are born alive. The female usually buries the eggs in the ground or hides them in the trunks of rotten fallen trees. Often she protects her eggs from animals who want to eat them. Small lizards sitting in an egg grow special "egg teeth" above the upper jaw. These teeth are used to break through the eggshell when it's time to hatch. And then those teeth disappear. Many lizards live in deserts. They are able to endure such heat and dryness in which many animals cannot live. Author: Likum A.
