Why Do Lizards Live That Long?

The major reason lizards live that long is because the life cycle takes about a minimum of 12 years to a maximum of 20 years to get completed.

However, with advancements in veterinary medicine and veterinary science, scientists found suitable conditions for lizards to survive for a longer duration of time. Moreover, with developed and improved knowledge about appropriate lizard care, good feeding habits, and all other survival situations, the average lifespan of the lizards can be increased from 2 years to about 3 years.

Lizards are not more vulnerable to survival problems like predators and food shortages. When taken proper care, provided safe and suitable shelter, a healthy diet, and an attentive owner, they can easily live up to 3 years.

Moreover, because lizards are a part of the food chain at a shallow level. That means, the animals which thrive upon other animals as food for their living, make lizards their prey. So, as a result, lizards fail to live long.

Unlike the wild lizards, the lizards who live under captivation can live for as long as a span of 20 years. This is so because these lizards have no stress to survive, they don’t have to struggle for food or fight predators. Such lizards are provided food and a good environment, they are far away from predators and thus, they have a long lifespan of 12 to 20 years.


Talking about pet lizards, one can live up to 2 to 3 years if healthy, provided needed care, and other essential needs like food and shelter are provided. Although, it is important to make sure that these pet lizards have equal health risks as compared to other domestic pets. If not taken care of or provided the needed diagnosis for their health problems, there is a big probability that these pet lizards will succumb to death due to several prominent illnesses.
