There are about 3,000 species of lizards.Though most lizards have four legs, some have only two legs and some are even legless.Depending on the species, lizards range from a few inches in length to more than 10 feet in length.Only two species of lizard are venomous: the Gila Monster and the Beaded Lizard.The tail of some lizards separate from the body when the lizard is grabbed.The tail that is left behind wriggles, confusing the other animal. This defense gives the lizard time to escape. Another tail will grow back, but it will be shorter and of a different color.
Most lizards can change color, making them more difficult to be seen by their enemies Lizard skin is covered with scales or plates that are made of the same material as human fingernails: keratin. Basilisks can run on their hind legs when threatened. They run fast enough to run across the top of water.The Gecko is the only lizard with a true voice. Some lizards have tongues that are longer than their entire bodies.Lizards use a Jacobsen's Organ, known scientifically as a Vomeronasal Organ, as opposed to a nose. They smell by tasting the air.
When the underside of their throats flutter, they are moving the air past the Jacobsen's Organ.The Komodo Dragon is the largest lizard in the world.Only the Chameleon and the Agamid lizards keep their teeth. All other lizards lose their teeth and replace them with a second set.
Some lizards, such as the Green Iguana, have a third eye on top of their heads.This eye does not form pictures, but does contain a lens and a retina-type structure.This connects to the pineal gland in the brain and governs hormone production related to basking time.They are found on every continent in the world except Antarctica
