How Long Frogs Live? (Frog Lifespan per Species)

Toads and frogs can have a much longer lifespan than most people think.

I had a pet toad in our yard as a child and he lived to be over 10 years old thanks to privileged access to food, shelter, and a safe environment.

On average frogs live 1 to 12 years in the wild and 4 to 40 years in captivity. How long a frog lives is influenced by the presence of food, predators, size, gender, and the overall quality of their environment. Captive Cane Toads have been recorded to live 40 years.

Continue reading to learn more about different types of frogs and their life expectancy, as well as what factors influence how long frogs can live.

Frog Lifespan Depends on Species

How long a frog lives is influenced by the species.

For example, American Bullfrogs are known to live 8 to 10 years in the wild and up to 16 years in captivity.

Northern Leopard Frogs generally live 4 to 5 years in the wild and up to 9 years in captivity.

Here are some of the frogs that are commonly found in North America, Europe, or Australia with their lifespan depending on the species and their location which may be in the wild or in captivity:

Frog Species LifespanWild (Years)Captivity (Years)
American Bullfrog8 – 1016
Spring Peeper46
Green Frog610
American Green Tree Frog46
American Toad1 – 1030
Black Rain Frog415
Cane Toad1015
Goliath Frog1521
Pacman Frog1 – 46 – 10
Northern Leopard Frog4 – 59
Blanchard’s Cricket Frog24
Gray Tree Frog79
Australian Tree Frog1620
Common Toad10 – 1240
Common Frog510
Narrow-Mouthed Frog3 – 5NA

Blanchard’s Cricket Frog live 2 years on average in the wild and up to 4 years in captivity.

Australian Tree frogs are known to live a long time in captivity up to 20 years, with an average lifespan of 16 years in the wild.

Although these examples are both frogs, they are different species of different sizes with different genetics which are factors that influence their life expectancy (CTNF).

Frog longevity is influenced by the presence of food.

Frog Lifespan Depends on Food & Predators

How long a frog lives depends on their access to food and the presence of predators.

If there is an abundance of food where the frogs live, and few predators around, they typically live for a longer period of time.

On the other hand, if it is hard for the frog to find food to eat, it can be harder for the frog to live a long life.

Also, if frogs are surrounded by thousands of predators and have few places to hide, it’s a recipe for disaster.

Although frogs have many smart defense mechanisms (check them out here) they can fail, putting their longevity at risk.

On the other hand, if there are no or very few predators, frogs can thrive and will eat anything that moves past them and can fit into their mouths.

Frog Lifespan is Influenced by Environment

How long frogs live is impacted by their environment which includes climate, human activity, and latitude. Let’s have a look at each in more detail.

Climate plays an important role in how long frogs can live.

If the climate is adapted to the frog species, they can live longer.

However, if the climate is unstable, ever-changing, or provides unfavorable conditions to frogs (ex. dry spells) the frogs could die or live shorter lives.

Human activity can play a role in influencing frog lifespan.

Urbanization, pollution, and destruction of habitats can force frogs to change their mating habits.

Polluted water can genetically modify frogs, stunt their growth, or kill them. It’s very important to care for our environment and protect vulnerable species.

Latitude may also influence frog longevity.

A study on Common Frogs across Europe found that “common frogs from subarctic regions (the northern boundary of this species distribution range) have an extremely long life span, up to at least 18 years” (Patrelle, Cecile., et al. 2012). 

The study suggests that latitude could play a role in reduced adult frog mortality rates “due to predation, reduced rate of aging due to short annual activity period in high-latitude environments.”

However, the authors of the study only open the discussion for other researchers to validate these hypotheses.

Size also plays a role in frog longevity.

Some studies tried to challenge the assumption that body size and age are strongly correlated in adult amphibians and reptiles and instead found that “growth rate prior to the age of first breeding is a much more significant source of variance in body size than age” (Halliday, T. R. et al. 1988).

Some scientific studies found that, somewhat like humans, female frogs may live longer than male frogs. 

Age was estimated using phalangeal skeletochronology and was significantly higher in females than in males.

(Fabio M. Guarino, 2019)

The following table contains the maximum frog age per species per gender based on scientific research:

Frog SpeciesAdult Male (Years)Adult Female (Years)
Common Frogs5 – 155 – 18
Taurus Frog67
Mantidactylus Grandidieri45 – 6

Therefore, how long a frog can live is influenced by many factors from the presence of food, predators, their species, environment, size, and gender.

Frogs tend to live  3 to 18 years in the Wild and an average of 10 to 20 years in captivity.

Few predators, more food, and adapted, stable environmental conditions can help frogs live longer.

Common Frog Longevity Questions

How Long do Little Frogs Live? Generally, little frogs live shorter lives than large frogs like the Blanchard’s Cricket Frog that can only live up to 2 years in the wild and 4 years in captivity compared to the American Bullfrog that can live 8 to 10 years in the wild and up to 16 years in captivity.

What Is The Maximum Age of a Frog? Generally, toads are the type of frogs that can live the longest with a recorded age of 40 years in captivity. Frogs generally live much shorter lives of about 5 years in the Wild due to the abundant presence of predators.

How Long do Toads Live? Generally, toads live 10 to 20 years in the wild and can live up to 40 years in captivity. How long toads live is influenced by the presence of food and predators, their gender, environment, and size.
