Are All Lizards Poisonous?

Lizards are disliked by everyone because they always look ugly and frightening. They climb on the walls and can even -`walk’ on the ceilings up-side-down without falling. But these small common lizards are not the only ones living on our earth. There are more than 2,500 different kinds of lizards but only two are actually poisonous. These are found in the American deserts, and in Mexico.

Lizards are cold-blooded reptiles like snakes. But unlike snakes, the bodies of lizards are divided into three part: head, trunk and tail. Most species of lizards have four legs, but some have no legs at all and look more like snakes.

Many species of lizards have an unusual capacity of discarding their tails. This often helps then in escaping enemy if it catches hold of their tail. Later, the lizard grows a new tail!

Lizards are hardy creatures and can adapt themselves to almost any surroundings. The lizards which live among grass or trees are coloured, but those living in the desert are dull gray or brown. Some kinds of lizards can change their colour to hide in the surroundings.

Most lizards are hatched from eggs. The smaller ones eat insects, but a few larger ones eat birds and small animals. Lizards like to live in warm climate. To escape cold, they hibernate or sleep during cold winters and again become active in summer.

The lizards we commonly see are small in size, about 7-8 centimeters long, but the bigger ones found in some countries can be as large as 3 meters long.
