A lizard is a reptile with overlapping scales and a fused lower jaw.  

Most lizards have eyelids, external ears, and two pairs of functioning limbs.

The Best Types of Pet Lizards

Experienced hobbyists have success keeping hundreds of different lizard species.

Here are the ones that are best suited for captive life with novice reptile owners.

1) Agamas

Bearded Dragons from Australia, also known as Pogona, sunbathing.
Their antics are an endless source of amusement for any lizard lover.

You may be wondering, “What in the world is an agama?!”

If you’ve seen lizards for sale in a pet store, you’ve likely seen an agama!

The bearded dragon is the most well-known agama species.

They’re one of the most common pet lizards. Bearded dragons are intelligent and easy to care for

2) Geckos

These adorable little lizards are famous for their big eyes and sticky toes.

Crested geckos and leopard geckos are the BEST pet geckos.

Crested geckos are arboreal and enjoy climbing. They’re comfortable at room temperature with high humidity. Cresties can thrive off of a commercially-made crested gecko diet. They enjoy fresh fruit and live insects as treats, and you can easily learn how to care for them.

Leopard geckos are terrestrial, so they require more floor space. They need higher temperatures and lower humidity, like the desert. A steady supply of live insects is required to keep them fed and healthy.

3) Skinks

Blue tongued Skink
Some skinks have no legs, while others have normal legs and necks.

Most skinks are heavy-bodied lizards with no pronounced neck and small legs. The best pet skink is the common blue-tongued skink. This interesting lizard grows to be about a foot long. Their husbandry requirements are simple and straightforward. Captive diets consist of canned dog food, fresh produce, and insects.

Other common types of pet skinks include:

  • Sandfish
  • Fire skinks
  • Monkey-tailed skinks
  • Peter’s banded skinks

The Most Famous Lizards

While these lizards may be well-known common pets, most of them are best left to the experts. Don’t worry: they’re so popular, you’re bound to see them in zoos and the wild.

1) Tegus

Black and White Tegu
Experienced owners refer to Argentine black and white tegus as the “dogs of the lizard world”.

Tegus are large lizards that are native to South America.

Their omnivorous diet consists of things like:

  • Fruit
  • Eggs
  • Fungi
  • Insects
  • Carrion

Argentine black and white tegus are famous as invaders of the southeastern United States. They’re also popular as pets.

These specialist lizards don’t make great pets for most people, though. They require large enclosures with specialized lighting. A tegu’s bite is capable of crushing human fingers. If now, you’re interested, check out its close cousin: The Caiman Lizard.

2) Anoles

Anoles are an important model organism for scientific studies. The Carolina anole was the first reptile to have its entire genome sequenced.

Walk into any southern backyard, and you’re bound to see dozens of lizards flee into the foliage. Many people also keep them as pets!

In most cases, those little lizards are anoles.

Anoles range in color from green to brown, and even have the ability to change their color. Males have a brightly-colored dewlap to attract mates and deter competition.

3) Chameleons

Most chameleons are arboreal, meaning that they live their lives in treetops.

Chameleons are one of the most famous types of lizard. Chameleons are well-known for changing colors, monocular eyesight, and their long tongue.

Some chameleons lay eggs, while others give birth to live babies. Chameleons can range in size from half an inch to over two feet long

Some of the most interesting and well-known chameleon species are:

The Most Fascinating Lizards on Earth

Lizards are a fascinating group of animals. Some have evolved unique adaptations to survive harsh conditions.

1) Horned Lizards

Flat tailed horned lizard
Horned lizards, or horny toads, have small, round, flattened bodies that are covered in spikes.

Their frog-like appearance isn’t even what makes them fascinating.

Horned lizards have “normal” lines of defense, like camouflage, fleeing, and puffing their body up.

If those don’t work, horny toads will squirt a stream of blood from the corner of their eyes! They aim for the perceived threat. The stream can reach up to five feet, and is intended to confuse their predators. The foul taste of their blood acts as a deterrent, as well.

2) Glass Lizards

Glass lizard in the wild
Glass lizards are considered lizards because they have a fixed lower jar, eyelids and external ears.

What a bizarre name for a lizard, right?

Scientists named glass lizards after their ability to “drop” their tail. They’ll voluntarily detach it from their body and make their getaway. Meanwhile, the predator remains distracted by the wriggling appendage.

That’s not all that makes them fascinating, though.

Glass lizards don’t have any legs!

At first glance, glass lizards resemble snakes. They’re considered lizards because they have a fixed lower jaw. They also have eyelids and external ears.

3) Whiptail Lizards

Whiptail lizards are plain-looking lizards that are native to the United States and Mexico.

Whiptail lizards are small, fast, and have long, whip-like tails.

Many species of whiptail lizards are hiding a genetic secret, invisible to the untrained naked eye.

Whiptail lizards were one of the first groups of lizards found to exist as a female-only species.

The lone females reproduce parthenogenetically. This means that they fertilize their own eggs by cloning their DNA.

The Most Dangerous Lizards

Lizards are usually regarded as harmless. Some specialized species pose a significant threat to humans.

1) Iguanas

Despite their reputation as friendly pets, iguanas can cause painful wounds.

Are you surprised to see that Iguanas made our “Most Dangerous Lizards” list? Most people think of iguanas as peaceful, herbivorous reptiles.

In actuality, their sharp teeth, large size, and whip-like tail make them a formidable threat when cornered or harassed.

Pet iguanas are even more dangerous. Their lack of fear and hormonal aggression leaves many owners with serious injuries every year.

But for anyone who’s really determined to own an iguana, perhaps the desert iguana is a safer option.

2) Monitor Lizards

monitor lizard or komodo dragon-min
Wild Komodo dragons were responsible for five human deaths in the past 40 years. There’s also been at least 24 targeted attacks on humans.

EVERYONE has heard of the infamous Komodo Dragon. Komodo dragons are the most famous type of monitor lizard. It’s no surprise that this group of lizards made it to this list!

Most injuries and deaths from monitor lizards occur in captive settings. Komodo dragons aren’t the only dangerous monitor lizards, either. The following species are also capable of putting a human in the hospital:

3) Beaded Lizards

beaded lizard, american agila monster-min
These medium-sized lizards are slow-moving and rarely grow over three feet long.

The last group of dangerous lizards is the beaded lizards. This genus includes the infamous American Gila monster.

They still have a deadly hidden weapon: venom.

Beaded lizards lack effective venom delivery methods. They need to chew and gnaw the venom from the glands into their perceived threat.

These lizards use their venom exclusively for self-defense. While beaded lizards are carnivorous, they prefer to take their prey down with brute strength.

Despite their potential, beaded lizards are docile in captivity, so human envenomations are rare. In instances where they do occur, patients seem to recover after several days of supportive care.


Q: How Are Lizards Different From Snakes?

Most lizards have fixed lower jaws, eyelids, limbs, and external ears. While lizards may lack some of these features, all lizards have at least one of these attributes.

All snakes have no limbs, hinged lower jaws that separate, no eyelids, and no external ears.

Q: Are Alligators Lizards?


Alligators are more closely related to dinosaurs and birds than they are to lizards.

One of the primary traits of lizards and snakes that crocodilians lack is overlapping scales.

Q: Are Lizards Smart?


Monitor lizards are regarded as the most intelligent type of lizard. Some studies have indicated that black-throated monitors have the ability to count up to six!

Q: Do Lizards Lay Eggs?

Most lizards lay eggs. Few lizard species, including some skinks, night lizards, and geckos, give birth to live young. The scientific term for these lizards is viviparous.

Q: Where Do Lizards Live?

Lizards live on every continent of the planet, except Antarctica!

They inhabit an astonishing array of habitats, including:

  • Rocky outcroppings
  • Forest floor leaf litter
  • Underground burrows
  • Treetops and rainforest canopies
  • Waterways and adjacent habitats
  • Marine environments and adjacent habitats
