There are about 5,600 species of lizards around the world.
- Evidence shows that lizards have been in existence on the earth for about two hundred million years and today’s lizards are a descendent of the dinosaur.
- Some lizards have the ability to ‘lose their tail’ when they feel danger is approaching. The tail will often twitch and move allowing the predator to think it is the lizard. They can grow their tail back in time and it is usually thinner and can be a different color.
Scientists are studying the lizard’s ability to regrow their tails to see what trigger in their body gives them the ability to do it.
- Some lizard species have tiny or small legs while others don’t have any legs at all. In the case of no legs they are often confused for snakes.
- There are some species of lizard that have the ability to replace their teeth all through their lives.
