Every year on August 14th, World Lizard Day celebrates this specific type of reptile. Lizards are found all over the world in almost every type of terrain. Some live in trees; others prefer to live in vegetation on the ground, while others live in deserts among rocks. Lizards are cold-blooded animals, which means they rely on their environment to help warm their bodies.

There are over 4,675 species of lizard, according to the San Diego Zoo. Lizards generally have small heads, long bodies and long tails. The largest lizard is the Komodo dragon. It grows up to 3 meters long and weighs up to 80 kilograms. Only two species are poisonous, the Beaded lizard and the Gila Monster, both from Mexico.


  • Reptiles have about one-tenth of the intelligence you’d find in animals like rats, cats, and hedgehogs.

  • The green basilisk lizard can run on water at about 1.5 meter per second for 4.5 m.

  • Chameleons' tongues are longer than their bodies, and their eyes can look in two different directions at once.

  • You can shine a light in a banded gecko's ear and the light will come out the other side.

Some lizards are territorial, while others can easily live with dozens of other lizards of many different species. Most lizards shed their skin in large flakes. Lizards also have the ability to break off part of their tails when a predator grabs it. The tail will eventually re-grow.

Many species of lizard also change colour in response to environmental changes or stress. One of the most well known lizards of this feature is the Chameleon Lizard. These lizards have special cells that lie in layers underneath their transparent skins.

Lizards typically feed on insects, birds or rodents. A few species are omnivorous or herbivorous. The marine iguana, which lives in the Galapagos Islands, eats algae from the sea. Most lizards lay eggs, though a few species are capable of live birth.

Nearly one-fifth of all known reptile species are considered endangered or dangerously close to extinction. Some lizards that are critically endangered include Campbell's alligator lizard, St. Croix Ameiva, Frost's arboreal alligator lizard, Be’er Sheva fringe-fingered lizard and the Doumergue's fringe-fingered lizard.
