Which of the Following Lizard Species Is Not Venomous


Do you know which lizards are venomous and which are not? Let’s explore four common types of lizards and learn the answer!

First up is the Gila monster. These come from the southwestern US and northern Mexico. They have black and orange bead-like skin with bumpy scales. Plus, they have modified salivary glands that produce venom – making them the only venomous lizard native to the US.

Next is the Bearded Dragon – they are not venomous and are popular pets. The name “Bearded” comes from their throat’s spikes. These look like a human beard when puffed up.

Thirdly, we have the Iguana. They can change color according to environmental conditions. Although non-venomous, they can lash out in defense by biting or whipping their tail.

Finally, The Green Anole is another popular pet. They feed on insects like crickets and cockroaches and are not venomous.

So there you have it – four common types of lizards and which one is not poisonous!

Bearded Dragon

Bearded Dragons can grow up to 24 inches long and can live for 10-15 years. Their diet consists of insects, veggies, and fruits.

Their courtship includes head-bobbing, arm-waving, and puffing up the beard.

These reptiles are very friendly to humans; they even recognize familiar faces, like their owners. They communicate through body language and vocalizations. So, if you want to keep a Bearded Dragon as a pet, ensure their well-being by providing a large enclosure that mimics their natural habitat. It should have a basking spot, UV lighting, fresh water bowl, substrate for digging and hiding, and climbing features.

When housing two Bearded Dragons, don’t place two males together as they may become aggressive. Also, make sure to keep the enclosure clean from feces, as it can cause health issues. And don’t forget about the chameleon – the ultimate master of disguise!


Camouflaging Reptile – Chameleons are incredible creatures with the ability to alter their appearance to match their surroundings. Depending on the situation, their skin can switch between colors, patterns, and textures!

A chameleon’s features include:

HabitatTropical and sub-tropical regions worldwide
Unique BehaviorTurret eyes

Not only that, but chameleons also possess a unique trait called turret eyes. This allows them to swivel each eye in different directions, giving them a 360-degree view!

In addition, some species of chameleons can even turn completely white or black as a defense mechanism against predators. (source: National Geographic) Move over, Game of Thrones. Komodo Dragons are the real stars of vicious battles!

Blue-tongued Skink

This species of skink, with its striking blue tongue, is easily identifiable. It’s known as the Blue-tongued Skink or Tiliqua scincoides, and belongs to the family Scincidae. Common names for it include the Australian Blue-tongued Lizard. Its habitat is Australia and Indonesia.

It’s omnivorous, eating plants, insects and small mammals. Blue-tongued Skinks can live up to 20 years and they’re really good climbers. Another interesting feature is their thick tails which they use to protect themselves from predators.

Research published in the Journal of Experimental Biology found that Blue-tongued Skinks have an unusual breathing mechanism when running quickly. Plus, these lizards are quite docile and easy to care for, making them popular pets. So, why have a regular green lizard when you can have a Green Anole, the diva of the reptile world?

Green Anole

The vibrant green lizard commonly found in the southeastern United States is a Green Anole. It has a slender body and a long tail. It is known for its ability to change colour.

Green Anoles are diurnal. They feed on insects, spiders and other small invertebrates. Also, they are semi-arboreal – they live in trees or bushes.

They can change colour for camouflage and communication purposes. Males use bright colours to attract mates. They also change colour when stressed or threatened.

To keep pet Green Anoles healthy, their enclosure needs hiding spaces and climbing material such as branches or vines. Temperature should be kept at 76-86°F during the day and lighting should be 10-12 hours a day.

Water is necessary for hydration. Mist the enclosure several times a day to maintain humidity. Feed them crickets or mealworms dusted with calcium powder twice a week.

By following these guidelines, Green Anoles make great pets. So, why have a dog or cat when you can have a pet with a crown? Check out the Crested Gecko!

Crested Gecko

This lizard species is known for its unique crested look, native to New Caledonia. They have round eyes and a prehensile tail, which they can regrow if lost at a young age.

Their skin can be brown, red, or green, and some have flame or harlequin patterns.

Crested geckos are arboreal, so they need a vertical tank with lots of room to climb. They feed on insects, nectar, and fruit, and drink water droplets from their tank’s surfaces. These creatures are active during the night, sleeping during the day.

The legend states that this gecko species was mistakenly thought to be extinct for two decades, before being rediscovered in 1994. Due to deforestation, some Crested Gecko populations were nearly wiped out until Robert Seamark found them while exploring a New Caledonia forest.

Non-venomous lizards can be identified by the lack of a ‘Beware of Lizard‘ sign.

Characteristics of Non-Venomous Lizards

The Unique Features of Non-Venomous Lizards

Non-venomous lizards have traits that set them apart from venomous ones. Here are some of them:

  • Their bodies are usually longer and leaner.
  • Their heads are narrower and eyes smaller, making it harder to spot prey.
  • They do not have heat sensitive pits around their eyes.
  • Their tails are longer to help with balancing.


These creatures can still cause harm if they carry salmonella in their saliva. So, before handling any non-venomous lizard, take safety precautions.

Fun Fact: Chameleons can have tongues twice as long as their whole body!

Also, make sure that the lizard you’re trying to identify isn’t just an old sock someone left outside.

Visual Identification of Non-Venomous Lizards

Non-venomous lizards can be identified with the naked eye. Pay attention to certain attributes to distinguish them from their venomous counterparts. Such as:

  • Body shape/size
  • Scales/skin texture
  • Head shape/eye placement
  • Tail length/form

Though some species look similar, it’s important to note the differences. Also, consider their habitat, diet, and behavior. If unsure, contact an expert. Understanding the distinction between venomous and non-venomous lizards can save lives – yours included!


The Bearded Dragon is the only lizard species not venomous. They are great pets due to their gentle demeanor; plus they are easy to tame and accept human interaction. Unlike Geckos, Iguanas, and Chameleons, Bearded Dragons are quite friendly!

These lizards are native to Australia and live in semiarid habitats like deserts and scrublands. They are part of the Agamidae family, which includes other dragon lizards.

Fascinatingly, Bearded Dragons use their “beards” to communicate. They puff out their beards when threatened or during courtship.
