While dinosaurs and lizards may have similar appearances, dinosaurs are actually an extinct group of reptiles. They are more closely related to birds than lizards.

There Are Over 6,500 Species

Lizards are classified in the suborder of reptiles known as Lacertilla. In this suborder there are over 6,500 different species! This number is constantly growing as we discover new species. In 2021 scientists discovered a new species in Peru called Liolaemus warjantay.

Some Species Don’t Have Any Legs

There is an entire group of over 200 species of lizards that have lost their legs. Legless lizards live all over the globe, but species like the Eastern Glass are found in the southeastern United States. Though they may look like snakes, they are actually lizards because they have external ears, eyelids and no forked tongue.

The Nano-Chameleon Is The World’s Smallest Reptile

The smallest species of lizard is a chameleon that can fit on the tip of your finger. The nano-chameleon was recently discovered in North Madagascar. A full grown male measures only 22mm from its nose to the tip of its tail.

Geckos Have Hairy Feet

Some Species Are Venomous

Most lizards are not venomous, but there are two exceptions. The Gila Monster is a venomous species whose venom is as toxic as a rattlesnake. They can be found in the deserts of Utah, Arizona, New Mexico and Nevada. The other venomous lizard is the Komodo Dragon which is not nearly as toxic as the Gila Monster.

They Like To Hide In Dark, Cool Places

Species you might find in your yard like to hang out in dark cool places like behind cupboards, furniture and in garden pots. If you want lizards in your backyard then try giving them various places to hide like a rock or brush pile.

Lizards Are “Cold-Blooded”

While their blood isn’t actually cold, lizards are ectothermic. This means they are unable to regulate their own body temperature and must use the sun to help warm their bodies.

Most Are Completely Harmless

The majority of lizards are completely harmless to humans. There are a few exceptions to this rule, and some lizards can have a pretty nasty bite.

You Can Pay Between $15 And $100 For A Pet Lizard

They were given this name because large groups of lizards were thought to lounge around together in the sun and wait for their prey to come to them.

Lizards Sleep Just Like Humans Do

While lizards and humans both sleep, their sleep cycles are a little different. Where humans will sleep in cycles lasting around 90 minutes, lizards usually will sleep in cycles that last a few minutes each. These cycles are much faster and more regular than human cycles. Scientists think these rapid cycles may be a more primitive sleep pattern.

They Are Smart Reptiles

People used to think reptiles weren’t very intelligent, but that opinion is changing. Scientists now think some lizards are pretty smart. Anoles have been seen forming strategies to capture prey and Monitors are able to recognize objects and count up to six!

Galapagos Iguanas Sneeze Salt

Galapagos Iguanas are marine reptiles that spend a lot of time in the ocean and eat large amounts of salt. To get rid of the excess salt in their bodies they sneeze it out!

Lizards Have A Third Eye

This third eye is called the parietal eye and is located on the top of a lizard’s head. It isn’t quite as noticeable as the other two eyes and is actually covered by skin. This eye is interesting as it can collect information about the time of day, ambient light and day length.

Certain Species Have Night Vision

Lizards that are active at night need to be able to see well in the dark. Crested Geckos are nocturnal and have vision that allows them to see at night. Their eyesight is so good that Geckos can tell the difference between blue and gray colors.

Carnivorous lizards are known to eat other, smaller species. When food is hard to come by these reptiles won’t hesitate to eat any smaller lizards they can find. Collared Lizards actually eat other species as a main part of their diet.

Lizards Have Ears And Can Hear Very Well

The holes on the side of a lizard’s head are actually their ears. Geckos can hear just as well as humans because they frequently vocalize to communicate and find their mates.

Most Will Run Away From You

Wild reptiles are generally more afraid of you than you are of them. Small lizards like Anoles will quickly run away from any approaching humans. Mediterranean House Geckos that live near people are more comfortable and will occasionally approach if food is offered.

Lizards Can Bite

When threatened lizards will use their teeth and bite. Most species that you will find in your garden like Anoles have small teeth that will barely even break the skin.

Armadillo Lizards Curl Up Into Balls

The Armadillo is a very spiky lizard that bites its own tail and rolls into a ball when threatened by a predator. This behavior makes it very difficult for a predator to get a good bite.

They Can Lay Eggs Or Give Live Birth

Some lizards lay eggs while others prefer to give live birth. One species of three-toed skink in Australia can actually do both.

Desert Species Have Spiny Toes

Some lizards in the desert have developed spines on their toes that help them run across the sand dunes without sinking in. If you have ever run on sand you will know how easy it is to sink in with each step.

Some species like the Leopard Gecko are able to regrow their tails, but not their limbs. If your lizard loses a limb it will not be able to grow it back.

Cool Facts About Lizards

The Parachute Gecko Can Fly

Parachute Geckos have unique flaps of skin on their feet, the sides of their body and their head. This skin acts like a parachute and allows them to glide from tree to tree.

Horned Lizards Can Shoot Blood Out Their Eyes

The Horned Lizard has a pretty unique defensive tactic. When threatened this reptile will shoot blood from their eye sockets which startles predators and gives them a chance to flee.

The Basilisk Lizard Can Walk On Water

Basilisk lizards are also known as the Jesus Lizard. They are given this name because they have special skin on their feet that allows them to run on water for up to 5 meters. They usually do this to escape from predators.

Anoles Can Breathe Underwater

Anoles can breathe underwater by trapping an air bubble to their snout. They are able to submerge for up to 20 minutes at a time!

Chameleons Can Change Color

Lizards like Chameleons can change color because of specialized skin cells called chromatophores. They don’t actually use this ability as camouflage, but to communicate with other reptiles. Male chameleons will display red, yellow and white to threaten other males.

Some Lizards Can Drop Their Tails

The Leopard Gecko can let go of its tail if it feels threatened! This is called autotomy and their severed tail will continue to wiggle to attract any predators away from the lizard. Normally they can regrow their tail in 6 months.

Most Don’t Swim

Most lizards are able to swim, but they can’t do it very well. Only the aquatic Marine Iguana spends lots of time in the water while searching for algae to eat.

Chameleons Can Look In Two Directions At Once

Chameleons have very interesting eyes that are able to move independently from each other. This allows them to look in two directions at once and have almost 360° of vision.

Some Drink Water Through Their Skin

The Thorny Devil is a species of Australian lizard that is adapted to desert life. Their mouth is so specialized to their diet of ants that they can’t actually use it to drink water! They absorb water through the skin of their feet and body.
