What is the snake life expectancy?

Quel est l’Espérance de Vie d’un Serpent ?

Nothing lasts forever on our planet. A snake, like all living things, has a finite lifespan. The average life span of each snake species is determined by its life expectancy. An in-depth investigation of a snake's life expectancy is a fascinating topic.

This article will focus on the largest number of snake species possible in order to research their lifespans in relation to their living situations. We'll also count down the snakes who have lived the longest, as well as the snakes who are the oldest and still living.

1. Life expectancy of constrictor snakes

Snakes are frequently classified based on how they attack. This paragraph will be dedicated solely to constrictor snakes like anacondas, pythons, and boas, with a focus on their lifespan.

A. Life expectancy of a Python

We'll start with the pythons because they can live for a long period. In captivity, that is, when it is kept in a setting where its breeder looks after it, the reticulated python can live up to 40 years, although in the wild, its life expectancy is between 15 and 20 years.

Python de Seba

Then there's the Seba python, a big snake that weighs up to 220 pounds. If the reptile lives in the wild, it has a 15-year life expectancy, but if kept in captivity, it can live up to 30 years.

Python molurus

We can also add the python Molurus, which can live up to 15 years in captivity but only 10 years in the wild.

python birman

Then there's the Burmese python, which is the world's second-longest snake. This python, on the other hand, has a long lifespan of 20 to 25 years. Some examples can live to be 35 years old. As a result, we may estimate that a python can live for 25 years on average.

B. Life expectancy of an Anaconda

If this is the average lifespan of the most common pythons, it's worth considering the lifespan of an anaconda.
With an average weight of 440 pounds and a length of 30 to 35 inches, this species of anaconda is the world's largest snake.

anaconda géant

The life expectancy of a green anaconda or giant anaconda is commonly stated to be 50 to 80 years, although this is not the truth; this snake lives on average for about 30 years.

anaconda jaune

The yellow anaconda is a different species of anaconda that isn't fully yellow. This snake is one of the top ten largest in the world. It has a comparable longevity as the green anaconda, lasting about 28 years if kept in captivity.

C. Life expectancy of a Boa Constrictor

Boa Constricteur

Among the constrictor snakes, the boa constrictor has a moniker that proves its identity. This boa differs from the other constrictor snakes we've seen because it lives for roughly 12 years.

2. Life expectancy of venomous snakes

When we think of snakes, we immediately think of their fangs, venom, and danger, as well as snakebite, envenomation, and poison. The bitten person is injected with venom by these predators.

Symptoms of a snake bite include nausea, blood clotting, and even death, depending on the species of snake that bit him. We'll also discuss the longevity of these so-called venomous animals.

A. Life expectancy of a Viper

To begin with, there are vipers, which are extremely dangerous and lethal snakes. This specimen, in fact, is one among those that can result in lethal bites.

Vipère de la mort

Most snakes in the viper family survive for up to 10 years, but the asp viper, which can live for up to 25 years, is an exception.

B. Life expectancy of a Cobra

Then there are cobras, which are venomous reptiles that we are all familiar with. The venom of cobras is highly startling and varies depending on the species.

The majority of cobra species are extremely dangerous. A cobra lives for roughly 20 years on average.

C. Life expectancy of a desert taïpan

Among these extremely hazardous venomous snakes, the Desert Tapan is the world's most venomous and deadly land snake, possessing neurotoxic venom. After being bitten by this snake, you will die the same day, sometimes in less than an hour.

Taïpan du désert

It has a life expectancy of about 15 years, which is average.

D. Life expectancy of a Mamba

Finally, we will journey to Africa, where we will see mambas, specifically the green and black mambas (Black Mamba). This mamba is the fastest snake in the world and also the deadliest.

Mamba vert

Indeed, its attack speed can reach 14 mps, leaving little time for its target to react. It has a life expectancy of up to 12 years.

3. Garter snake life expectancy

Because of their lethal reputation, many people are scared of all snakes. Some species, on the other hand, are completely harmless. The garter snake, which is sometimes found in the garden, is a frightening snake whose bite is not deadly; it does not release venom, thus when bitten, it does not release poisons.


It has a life expectancy of 16 to 28 years, depending on lifestyle and living conditions.

4. The snake with the longest life span

We didn't talk about this snake among the pythons because it was a surprise, but it's vital to mention it. The royal python, scientific name python regius, is now the snake species with the longest life expectancy. In fact, while in captivity, it has a life expectancy of 40 years or more.

python royal

It is not a venomous snake; rather, like all pythons, it is a constrictor, which means that it wraps itself around its prey to immobilise, suffocate, and kill it.

It is, in fact, venom-free. It is the smallest of the pythons, measuring 47 inches in length, or ten times shorter than the Reticulated Python, the longest of the pythons and the world's longest snake with a length of up to 3 ft.

The royal python is quite popular as a pet due to its small size, and many people breed this python because of their high demand for its colour, which is very varied and attractive.

Because the royal python is the world's longest-living snake, it's only natural that the world's oldest snake is a 47-year-old royal python. It is maintained in a cage.

In summary

A snake's typical lifespan is roughly 15 years. The reason for this longevity is due to the law of nature, which states that only the strongest survive for long periods of time. In addition, because most snakes are under 10 ft long and small, they are easy food for other predators.

We've ranked the most common and well-known snakes by size and venomousness in this page. Wouldn't it be fascinating to conduct a thorough investigation on the world's most dangerous snakes? Which are the world's largest? Which ones are the world's longest? Shouldn't we also look at the ones that these snakes eat in order to live longer?
