Lizards can be found across all continents except Antarctica. Lizards typically have feet and external ears, and range from the half inch (1.5 cm) of the smallest gecko to the more than 10 feet (3 m) of the dragon of Komodo. In weight, they range from 5 ounces (140 g) to more than 250 pounds (113 kg). A number of lizards are shaped like toads with short tails, and others like snakes and worms. Most have well-defined heads and necks, elongated bodies, and tapering tails. Most lizards have four limbs, each ending in five clawed toes. Some have only vestiges (traces) of limbs in their skeletons.

Here at the Zoo which house a number of species of Lizard, however the beaded lizard is very special, as it one of only 2 venomous lizards found in the world.
