2. They are present everywhere except the continent Antarctica. They can be as small as 1.6 cm to as long as 11 feet. Some lizard species can weigh up to 166 kg (weight and length of the lizard varies with the species). Depending on the species, they may live anywhere from one year to 30 years.

3. There are few species of lizards who look similar to the snakes because their legs are so small that they are not visible or they don’t have legs at all. So, people often mistake these lizards to be snakes. To identify whether it is a snake or a lizard, one has to focus if the animal has eyelids and external ears. If yes, then it is a lizard, not a snake.

4. Komodo Dragon is the largest lizard. It is seen only in the Komodo islands of Indonesia.

7. There are some species in lizards that squirt blood from their eyes to protect themselves from the predators or when they feel that there is some kind of threat. They can do this with the help of “horns” which are present near their eyes. The blood squirted from the eyes can go for a distance up to 4 feet.
