The Lizard Family

Hello! Let me introduce myself. I am a lizard, and proud of it! Let me tell you why.


There are many lizards on planet Earth; in fact, there are more than 5,000 species, or kinds of us. You might know of a few species that some people keep as pets: chameleons, bearded dragons, and iguanas. We are all like cousins in one big family.

In the animal kingdom, our family name is reptile. Not all reptiles are lizards, but all lizards are reptiles. Snakes, turtles, and crocodiles are also part of our big reptile family.

As a reptile, I am cold-blooded. This means that my body has to be warmed up and cooled down from the outside. This is why you can find me lying around on rocks and branches in the sun. Basking in the sun raises my body temperature and gives me the energy I need to move around.

As a reptile, I also have skin that is covered with scales. Scales are small boney plates. Look closely for scales on the skin of my cousin here:

Rhinoceros Iguana

One of my most interesting features is my tail. Lizards have long tails that can grow back if they get broken (or bitten) off. Another interesting fact is that I have a tongue like you do, but I use mine to smell things! Imagine having to stick out your tongue to smell a flower!

I also have a few things in common with humans! Both humans and lizards have backbones and lungs for breathing air.


My family is very diverse. This means that each species looks and behaves in its own special way. Overall, we share common features like scales, long tales, backbones, lungs, and being cold-blooded.

We come in many different sizes, shapes, and colors. Sometimes, our colors are bright and beautiful; other times, they blend in with the colors of nature. The colors and shapes of our bodies depend on our environments.

Diversity of Lizards

Some of us are as small as a finger; others are larger than a big bicycle. Most of us are in between.

Most of us have four legs, but a few have only two legs or no legs at all!

Each of our different features has a purpose: to help us find food, hide from other animals, and find a mate.
