how long do lizards live

Are you interested in getting a pet lizard that can live with you for many years? If yes, then this post is a must-read for you. Because in it I will share with you everything you need to know about the lifespan of lizards, the best pet lizard species based on lifespan, and a guide to help you make sure your pet lizard lives a long and happy life. 

Everything You Need To Know About the Lifespan of Lizards

Lizards are classified as reptiles in phylum Chordata. There are over six thousand species of lizards known to man. While all lizard species are lizards, they are all different from one another. This is the reason they all have different lifespans. Some live long lives while others live relatively shorter lives.

In general, pet lizards live longer lives than wild lizards. This is because pet lizards are not threatened by predators in the same way wild lizards are. The fact that wild lizards are threatened by predators makes them more likely to be harmed or killed and hence their shorter lives.

Several other factors affect how long lizards live including their size and their species. 

The average lifespan of all lizard species is between 1 year and 50 years depending mainly on the species. In other words, some lizards live for about one year while others live for as long as 50 years.

The Best Pet Lizard Species Based on Lifespan

If you are looking for the best lizard species based on lifespan, this is where you will discover them. Because in this section, I will reveal to you the best pet lizard species based on lifespan.

The species live long and they have the added advantage of being some of the best lizards for beginners. This is because they are quite easy to look after. They are also quite easy to feed and to interact with. The lizards are the leopard gecko, the bearded dragon, the blue tongue skink, and the crested gecko.

  1. The Leopard Gecko

Leopard Gecko

A well taken care of leopard gecko can live up to twenty years. It is one of the longest living lizard species you can get and keep as a pet.

The best thing about it is the fact that it is quite attractive to look at. The leopard gecko is also easy to handle and very friendly.

It grows to a maximum length of 10 inches so it requires a roomy enclosure.

If you decide to get a leopard gecko as a pet, you should get it UVB light to boost its immune system. You should also get it calcium and multivitamin supplements to make sure it stays strong and healthy. 

  1. The Bearded Dragon

Bearded Dragon

If you take good care of a bearded dragon lizard, it will live with you for many years. This is because it has an impressive lifespan of 15 years.

The best thing about the bearded dragon (despite its scary name) is the fact that it is very friendly and docile. If there is a lizard that is unlikely to hurt you it is the bearded dragon.

If you decide to get this lizard as a pet, you should get it UVB lighting and lukewarm water. Without both in its enclosure, it will quickly become sick and die.

  1. The Blue Tongue Skink

Blue Tongue Skink

Blue tongue skinks can live for more than twenty years. This definitely warrants their inclusion to this list of best pet lizard species based on lifespan.

As its name suggests, the lizard has got a blue tongue. This makes it very unique. The tongue is long and the lizard is known to use it to deter predators. 

Another thing that makes the blue tongue skink unique is the fact that it can drop its tail quickly to escape a predator if it is grabbed by the tail.

If you decide to get this lizard as a pet, you should get just one. If you get two, they will fight unless you build them a massive enclosure. This is because they are quite territorial.

  1. The Crested Gecko

Crested Gecko

If well taken care of, a crested gecko can live for more than twenty years. It is one of the longest living pet lizard species. 

One of the best things about crested geckos is the fact that they are not too large. They grow to a maximum length of 8 inches and can, therefore, be accommodated in relatively small 20-gallon tanks. 

If you decide to get a crested gecko, you should keep half of its enclosure warm and the other half cool to allow it to regulate its body temperature as it deems fit. Because if it gets too cold or too hot, it could die.

How to Make Sure Your Pet Lizard Lives a Long Life

So you now know the best long-living lizard species to keep as a pet. However, just because a lizard has a long lifespan does not mean it will live for a long time. A lizard will only live for a long time if it is well taken care of.  Below are the things you need to do to take good care of your pet lizard and make sure it lives a long and happy life.

  1. Build a Decent Enclosure

If you want your pet lizard to live for a long time, you need to build it a decent enclosure. Simply buying a glass tank and putting random decorations in it is not enough. You need to build an enclosure with the perfect lighting, humidity, and heating conditions for your lizard. You also need to make sure the enclosure the right size and has just about everything your lizard would need or use if it were in its natural habitat.

  1. Give Your Lizard the Right Food

If you want your pet lizard to be strong and healthy and to live as many years as possible, you need to feed it with the right food. If you feed your lizard with just crickets, it will not live for long. Your lizard needs a diverse diet to get as many different micro and macronutrients in its body. So research all the foods your lizard can eat and try to give it a balanced diet every week. 

  1. Clean Your Lizard’s Enclosure and Give It Fresh Water Daily

Lizards, like many animals, are not very intelligent. They defecate where they eat. They also swim in the water they are supposed to drink. Therefore, if you do not clean your lizard’s enclosure daily and give it fresh water daily, it will end up consuming dirty food and water and become sick. So if you want your lizard to stay healthy and live a long life, you should clean its enclosure and give it fresh water every day.

  1. Give Your Lizard Calcium and Vitamins

Insects bought from pet stores are usually not very nutritious. This is primarily because they are fed store-bought food, unlike wild insects that eat many things in nature. So if you are giving your lizard store-bought insects only, it will not be very healthy and strong. You need to diversify its diet and you also need to give it calcium and vitamins to make sure it is healthy and strong.

  1. Get Your Lizard a Roomie

As humans, we get lonely when we do not have company. The case is the same with many lizard species. While many lizards like living alone, many lizards also like living in a community. Therefore, research if your lizard likes living alone or in a community and if you find out it likes living in a community, get it a compatible roomie. Lizards that like living in a community are happier in a community and, therefore, live longer in a community.


Lizards live between 1 year and 50 years based on their species. This means that some lizards can only live for about one year while other lizards can live for as many as 50 years. The best lizards to keep as pets based on longevity are leopard geckos, bearded dragons, crested dragons, and blue tongue skinks. This is because they have very long lifespans; they can live to between 15 and 20 years. However, if you get one of them and you do not take good care of it, it will not live for long. 

So if you decide to become a lizard pet owner, you should take good care of it, if you want it to live a very long life.
