In wild, an adult newt can reach up to the age of 14 years. On the other hand, newts can live long for 6-10 years or up to 20 years in captivity. Also, their lifespan varies according to their species.

In this article, we will discuss elaborately how long newts live, factors determining their long lifespan, and so on. Let’s go through this article without further ado.

Average Lifespan Of Newts

It’s not any surprise that newts can be good food for many predators. As a result, their average lifespan gets shorter. If newts can save themselves from predators, they may manage to live long.

We’ve found out that the average lifespan of newts is 14-20 years. In wild, there are records of their living for long 17 years.

To fathom other factors related to newts’ average lifespan, we’ve to notice their life cycle. All species of newts go through multiple transformations throughout their life.

You’ll see four phases in their life. Firstly, their life starts at the eggs phase. After that, the larval newt turns into a tadpole. Finally,  it becomes a grown-up newt.

Throughout their life, newt lives on both land and water. Again, some newts live in water throughout their entire life.

So, we can say that newts are either aquatic or semi-aquatic. For this, predators from both places risk newts’ average lifespan. Though tiny newts leave water early, they return to the water for breeding at the age of two.

How Long Do Common Newts Live?

Many people ask how long common newts live. You might know that common newts are also called smooth newts. Because their skin becomes smooth after migrating into the water for breeding.

An adult common newt can live long for 6-14 years in the wild.

Potential Reasons Of Newt’s Not Living Long

Precisely newts aren’t immortal. But they can manage to live long for many years. Nevertheless, there are many reasons for which newts can’t live long.

Hence we’ve summed up some potential reasons for newts’ early death or short lifespan. Let’s check them out.

Habitat loss :

Habitat loss is a great cause of why newts do not live long. We’ve mentioned before that newts are either fully aquatic or semi-aquatic. So, ponds, lakes, mud bottoms, moorland, ditches, etc are the perfect habitats for newts.

If that watery land dries up, only adult newts can survive their life on land. Otherwise, larvae newts can’t live long without water.


Predation is another notable reason. The threat of predators risks the average lifespan of newts. Newt’s common predators are fish, frogs, herons, grass snakes, etc. Many newts can not manage to live long or become adults due to the attack of their predators.

Extreme Weather In Winter:

Newts die because of overwintering. Hence, they search for suitable shelter that keeps them free of frost. For example – muddy bank of ponds, composed heap, etc. Albeit, extreme weather in winter reduces newt’s longevity.

Dehydration In The Summer:

Although newts can tolerate the heat of summer, dehydration causes their early demise. Also, aquatic newts are the main sufferer of this. This leaves us with the question of whether newts can cope with heat or not.


Newts can’t live long being affected by diseases as well. However, their diseases can be spread from various parasites too. Also, a new deadly new disease is Bsal which makes them quite extinct now.

Pollution :

Not to mention, pollution puts serious effects on newts. Also, this makes them stressed in their habitat. As a result, pollution results in newts’ short lifespan.

Final Words

Newts are remarkable, tiny, and interesting creatures. Furthermore, we need to take proper steps to save newts from extinction. Because our little deeds can make them live longer than our expectations.
