About This Quiz

It's mind-blowing to think that there are species of lizards on Earth right now, just basking in the sun on a rock somewhere, that have barely changed at all in millions of years.

Lizards are just a hearty group of little beasts that seem to be able to endure a lot and keep on keeping on. They're also incredibly cool. From the tiniest little gecko you can keep as a pet in a tank in your house where it might eat a cricket a day, to the massive and terrifying Komodo dragon which can take down man-sized prey, there's a wicked diversity in the world of lizards. 

It's hard not to be fascinated by these throwbacks to prehistoric times. They're like a living reminder of a history we can never truly know, of what the world might have looked like long before humans ever showed up. That's a pretty cool thing, and it deserves a little respect and recognition.

Speaking of recognition, now's your time to shine by showing us how many species of lizards you recognize. There are many of them in the world. Do you think you can pick out 40 of them? Let's find out!

Satanic Leaf-Tailed Gecko You can find this nefarious creature in Madagascar. What's it called?
Black and White Tegu
Crested Gecko
Satanic Leaf-Tailed Gecko
No animal has a more hardcore name than the satanic leaf-tailed gecko. It also doesn't really deserve the name since it's not particularly evil in any way. Luckily they also go by the names "eyelash leaf-tailed gecko" and "phantastic leaf-tailed gecko" so it's not all doom and gloom.

Plumed Basilisk This lizard can run across water for short distances. What is it?
Plumed Basilisk
The plumed basilisk of Central America is a unique animal in appearance and behavior. The plume from the name is very noticeable and gives the lizard a dinosaur-like appearance. Using its tail to stay upright, it can run for a little while on the surface of the water if it falls, no worries because it's an excellent swimmer as well.

Nile Monitor This lizard can grow to be larger than a human. What is it?
Collared Lizard
Red Tegu
Knight Anole
Nile Monitor
The largest Nile monitor on record managed to crack 8 feet, making these enormous lizards indeed. Adult males can be very aggressive, which, combined with their size, makes them dangerous to be around. They are native to Africa, but populations do exist in places like Florida now as well.

Marine Iguana You can only find this lizard on the Galapagos Islands. What is it?
Gidgee Skink
Marine Iguana
Marine iguanas are unique among lizards thanks to the fact they are marine reptiles and the only lizard that forages in the sea. They eat algae in their native habitat, and no one has ever successfully bred or kept them away from the Galapagos Islands.
Mangrove Monitor
Frilled Lizard

Green Anole This lizard sometimes goes by the name "American chameleon." What's its more formal name?
Mali Uromastyx
Gold Tegu
Desert Iguana
Green Anole
The green anole is a very popular lizard to keep as a pet and is sometimes called an American chameleon because it can change from bright green to a somewhat muted brown color to blend into its surroundings.

Veiled Chameleon In Hawaii, this lizard has become an invasive species. Do you know what it is?
Grand Cayman Blue Iguana
Veiled Chameleon
Veiled chameleons are popular lizards to keep in captivity since they're pretty easy to handle, relatively speaking. That has led to a number of them being released into the wild. This, in turn, has led to the population of invasive chameleons you can find in Hawaii right now.
Cape Monitor
Frilled Lizard

Red Tegu Name this bulky lizard that can grow to 4 feet in length and makes an oddly good house pet.
Red Tegu
Red tegus are very popular pets as far as lizards go because, if you have space and the ability to care for a massive lizard, they behave quite a bit like dogs. They'll follow their owners around the house, eat and drink from pet bowls and can even be clicker trained.
Desert Iguana
Centra American Banded Gecko

Australian Water Dragon Swimming and climbing are two of this lizard's strengths. Name it!
Prehensile-Tailed Skink
Bibron's Gecko
Australian Water Dragon
Australian water dragons are, as the name suggests, very well adapted to the water. They can swim submerged and stay underneath the water for about an hour and a half if necessary.

Bearded Dragon This Australian lizard is kept as a pet throughout the world. What is it?

Blue-Tongued Skink Because of its little legs, this lizard is pretty slow. What is it called?
Caiman Lizard
Green Water Dragon
Blue-Tongued Skink
Blue-tongued skinks are native to Australia but are also reasonably popular as house pets. Because they have such thick bodies and tend to move slowly, they're easy to handle and are well adapted to being kept as pets. They also rarely show off that blue tongue, so getting bitten by one is often not an issue.

Burton's Legless Lizard No, it's not a snake. What is it?
Spiny-Neck Monitor
Green Basilisk
Asian Water Monitor
Burton's Legless Lizard

Crocodile Monitor
Argus Lizard
Thorny Red Dragon

Flying Gecko This lizard's camouflage is so good, it's nearly impossible to see it in the wild. Name it!
Flying Gecko
Flying geckos, like most flying animals that don't have wings, have adapted flaps of skin that allow them to glide between trees. Their flesh is highly camouflaged, and if they have their eyes closed, they become nearly indistinguishable from the trees in which they live.

Gila Monster This is the only venomous lizard in the United States. Name it!

Silver Monitor

Jackson's Chameleon This African lizard can now be found in Florida, Hawaii and California. What is it?
Jackson's Chameleon
Jackson's chameleon is one of the easiest to identify lizards in the world thanks to the three horns on its head that make it look like a little triceratops. Because they are so widely coveted as pets, a number of specimens have been let loose in non-native habitats, and populations are springing up across the United States.

Komodo Dragon This is arguably the biggest, most dangerous lizard on Earth. What's it called?
River Monitor
Komodo Dragon
No one on Earth would ever keep a Komodo dragon as a pet and for good reasons. These lizards reach lengths of up to 10 feet, and their toxic bites could very well kill a human if left untreated. The claws of a Komodo dragon can rip cages apart. Komodo dragons are fun to see at a zoo, but it's probably never a good idea to get close to one.
Fire-Bellied Dragon
Rock Iguana

Advertisement

Moloch Another name for this lizard is "thorny devil." What else is it called?
Moloch
Moloch is the name of a Canaanite god from the Bible who later became associated with demons, so this poor lizard has a bad reputation from the start. Its intimidating names likely come from the fact it's covered from head to toe in an array of very sharp-looking spikes that it uses for self-defense.
Mountain Horned Dragon
Green Tegu
Argus Monitor

Monkey-Tailed Skink These herbivores are known to eat toxic plants with no problems. What are they?

Jeweled Lacerta
Fat-Tailed Gecko
Gold-Dust Day Gecko

Mexican Beaded Lizard A bite from this lizard will lead to a solid day of excruciating pain. What is it?
Green Anole
Feathered Uromastyx

Northern Alligator Lizard You can find this lizard along the Pacific Coast and up to the Rocky Mountains. What is it?

Red Tegu
Caiman Lizard
Mangrove Monitor

Sungazer People sometimes call this the "giant dragon lizard." What other name does it go by?
Gold Tegu
Sungazer
Sungazers live in Africa and grow to be about a foot long to the tip of the tail.

Lined Day Gecko
Brown Anole

Texas Horned Lizard This lizard will sometimes be called a frog or a toad, even though it's neither one. Name it!
Texas Horned Lizard
Texas horned lizards live throughout the Southern U.S. and into Mexico. They're actually members of the iguana family and as cool as they look, they're extremely hard to keep as pets because their diet is monstrous. One of these little lizards can eat a few thousand ants per day, much more than the average pet owner can supply.
Argentine Tegu
Southern Alligator Lizard
Beaded Lizard

Tokay Gecko They named this lizard after the sound it makes. What is it?
Shingleback Skink
Rhinoceros Iguana
Tokay Gecko
Tokay geckos are native to various parts of Asia and are known for their frog-like croak. Some people say it sounds like the gecko is saying "tokay" but it's also described as something like "geck geck" and "poo-kay." Soldiers in Vietnam also gave it a rather vulgar nickname that you can Google if you want.
Argus Monitor

Tuatara In a very technical way, this little New Zealander isn't even a lizard. What do you call it?
Flying Gecko
Panther Chameleon
Mangrove Monitor
Tuatara
Tuataras look like lizards but evolved along a separate but similar path. They're a little more prehistoric than your average lizard and likely have been around for 200 million years or so. They also tolerate much colder weather than most lizards, and they are comfortable in temperatures in the mid-60s and even high 50s.

Savannah Monitor These lizards are sometimes trapped for their leather. Do you know what they are called?
Savannah Monitor
Savannah monitors are native to Africa, though there is a relatively prominent illegal trade in the lizards. Animal rescues that deal with lizards often get them, since people who take them in as pets abandon them when they aren't prepared to care for the lizards once they reach 3 feet in length!

Eastern Fence Lizard Some people call this a prairie lizard or a pine lizard. What else is it called?
Desert Iguana
Veiled Chameleon
Argentine Tegu
Eastern Fence Lizard
The Eastern fence lizard is found throughout the Eastern United States and gets its name from the fact that you can very often find them basking in the sun on top of fence posts. They're usually gray or brown, and that helps them blend into their surroundings, which is helpful when you're on top of a fence all day.

Dumeril's Monitor This lizard eats mostly crab, but it may try some other fish or rodents in a pinch. Name it!
Gidgee Skink
Dumeril's Monitor
The Dumeril's monitor can be found in Southeast Asia where it can grow to upwards of 4 feet in length. Generally speaking, you don't want to run afoul of one of these lizards, and keeping one as a pet can be tricky since they spend much of their time in aquatic environments.
Sungazer
Water Monitor

Frog-Eyed Gecko This desert lizard could live up to 20 years in captivity. What's it called?
Frog-Eyed Gecko

Crocodile Monitor
Knight Anole
Moloch

Jeweled Lacerta You can feed this little fellow bugs or smashed fruit. Do you know what it's called?
Jeweled Lacerta
The jeweled lacerta, or ocellated lizard, is native to Europe and is typically not a fan of human interaction. They're fast little things and will be quick to run for cover if they sense danger.
