Do animals have shorter lifespans in zoos?
A study of more than 50 mammal species found that, in over 80 per cent of cases, zoo animals live longer than their wild counterparts.
The zoo protects the other animals in the study from threats, from predators to starvation, that shorten their lifespans, but with animals that face few threats, there's not as much for the zoo to protect them from, Dr. Clauss said.
An Asian elephant in a European zoo. An adult female elephant, her adult daughter and their calves in a natural, free-range population. Living in a zoo shortens an elephant's life, according to a new research study published in the journal Science.
Nutrition: Animals in captivity may receive a more controlled and balanced diet than those in the wild, which can lead to a longer lifespan. On the other hand, if their diet is not properly managed, it could lead to health problems and a shorter lifespan.
On average, captive animals (especially mammals) live longer than wild animals. This may be due to the fact that zoos provide refuge against diseases, competition with others of the same species and predators.
Recently, a study conducted by University of Lyon and University of Zurich researchers found that 80% of the mammals studied lived longer in a zoological setting than their wild counterparts. The study analyzed zoological databases and included over 50 different mammal species.
Captive: Captive elephants have significantly lower life spans than their wild counterparts and are usually dead before the age of 40. Captive elephants suffer from chronic health problems, such as tuberculosis, arthritis, and foot abscesses, which nearly always lead to premature death.

That captivity can be REALLY bad for both physical AND psychological health. And while zoos have been really helpful is saving endangered animals, it doesn't work out for certain species. For example, most large carnivores like lions and tigers that are bred in captivity die when released into the wild.
Key differences between animals in wild vs in captivity
Additionally, wild animals may have greater genetic diversity and adaptability than those in captivity. This allows wild animals to better survive in changing conditions, while captive animals may be more vulnerable to environmental changes.
Which animal has the shortest lifespan in captivity?
| Rank | Animal | Lifespan |
|---|---|---|
| 1 | Mayfly — The Shortest Lifespan of Any Known Animal | 24 hrs |
| 2 | Ruby-Throated Hummingbird — One of the Shortest Lifespans of Any Bird | 3 to 4 years |
| 3 | Labord's Chameleon — The Shortest-Lived Lizard | 4 to 5 months |
| 4 | American Copper- The Shortest Lifespan of All Butterflies | 2 weeks |
While there is a lot more science that can be done to answer that question, the answer seems to be: no, not if they're cared for well in captivity. The more we study animal behaviors, the better we get at figuring out what they need to pursue their own happiness, even when they are not allowed to be 'free. '
For most species (84%), longevity was higher in zoos than in the wild. The onset of senescence was the same or later in zoos than in the wild for about 69% of species. These effects were greatest in species with a faster pace of life (shorter life span, higher mortality rate, and earlier onset of senescence).
Explanation: Big cats ( tigers), reindeer and African buffaloes lives the longest in zoos.
Zoos can help to save endangered species by keeping them in a 'safe' environment. Safe as in protected from poachers, predators, habitat loss and even starvation. If a zoo has a breeding programme, this is another way to protect endangered species which may have trouble finding suitable mates in the wild.
Zoos and aquariums accredited by the Association of Zoos and Aquariums (AZA) have one shared goal. They strive to save and sustain the planet's wildlife by caring for endangered and threatened species in human care and conserving natural spaces.
Captive animals seldom learn crucial survival skills and often are too habituated to human contact. Lacking a natural fear of humans, they are vulnerable to poachers and ill equipped for life in the wild.
AZA and AZA-accredited zoos and aquariums frequently partner with other organizations, including government agencies, to protect endangered species and their environments. Zoos and aquariums are an essential part of the recovery program for many endangered species listed under the Endangered Species Act.
Wild and Long-Lived
The findings show that captive elephants live considerably shorter lives. For African elephants, the median life span is 17 years for zoo-born females, compared to 56 years in the Amboseli National Park population.
Due to their physical size, complex social needs, high level of intelligence, large home ranges, diverse diet and large behavioural repertoire, the full welfare needs of elephants cannot be met in captivity.
Why do animals live in the zoo?
Having animals in protection provides a reservoir against a population crash in the wild. Zoos have helped remove animals from the endangered species list and have saved many from extinction. Without the efforts of zoos, there would be fewer animal species alive today!
Zoos can be educational institutions, providing valuable information about animals from all over the world; they can also be conservation centers, helping to protect endangered species and promote breeding programs that increase the population of threatened animals; and zoos can be entertainment venues, offering a fun ...
Polar bears are the animals that do worst in captivity. Carnivores such as polar bears, tigers, cheetahs, and lions are especially poorly suited for life in a zoo, according to a new study. The more an animal roams in the wild, the researchers found, the worse it fares in captivity.
Dewitz noted that some zoos may choose to bury some animals rather than cremate them, but “they probably have very secret locations where they're buried.” Even the way in which the cremated remains of an animal are interred is kept closely guarded. “It's just disposed,” Dewitz said quietly.
Six Species Saved From Extinction by Zoos
As of 2017, 1,000 animals had been restored to the wild, while thousands more were living in zoo environments. Przewalski's Horse: The only truly wild species left in the world, Przewalski's Horse is native to the grasslands of Central Asia.
Zoos engage in research, preserve biodiversity (genetic and species) that may be threatened or at times even extinct in the wild, and they provide much needed funding for research and conservation projects across the world.
Repetitive, often destructive behaviors like swimming in circles, grinding their teeth, and bobbing their heads are all symptoms of the effects of captivity on the animal's brain.
The dainty mayfly, an insect found worldwide in clean freshwater habitats, lives for just one or two days, the shortest lifespan of any known animal.
Males born in the Lesotho have the lowest life expectancy of the world in 2022. Similarly low is the life expectancy for females born in this country. The average woman lives only 56 years. The lowest life expectancy for women in the world in 2022 was for girls born in Nigeria, with only 54 years.
Had it not been for zoos, we would have never been able to see what some animals looked like. We enjoy their behavior and it also creates awareness about the extinction of the rare species. Similarly, zoos are a safe breeding ground for animals. They ensure the animal breeds so they never go extinct.
Which animals should not be kept in zoos?
For example, elephants, big cats, and primates are often cited as animals that do not thrive in zoo environments due to their need for space, social interaction, and mental stimulation.
The smarter ones, such as great apes and elephants, almost certainly do. The rest probably have no particular grasp of that idea. They do realize they're confined to a specific area and can't find a way out. They realize that humans are present in their environment, and bring them food.

The California Condor was once on the brink of extinction — there were only 27 left. The birds were taken into captivity to begin a breeding program to help save the California Condor from extinction.
While zoo advocates and conservationists argue that zoos save endangered species and educate the public, many animal rights activists believe the cost of confining animals outweighs the benefits, and that the violation of the rights of individual animals—even in efforts to fend off extinction—cannot be justified.
On that basis, most vegans consider zoos to be exploitation of, and in many cases, cruelty to animals. Would an animal choose to remain in that environment if it had the option? If you are vegan and your answer to the question is no, most likely you disapprove of zoos.
According to evolution theory, animals that face high extrinsic mortality such as predation and infectious diseases must develop quickly (i.e., live fast) in order to pass their genes onto the next generation before death occurs, while animals that face low extrinsic mortality delay development and reproduction, and ...
Some fish, such as some varieties of sturgeon and rougheye rockfish, and some tortoises and turtles are thought to be negligibly senescent, although recent research on turtles has uncovered evidence of senescence in the wild.

- Kangaroo - 8 years. ...
- Domestic dog - 12 years. ...
- Cats are known to live longer than dogs. ...
- Giraffe - 25 years.
Only recently has there been enough data on the longevity of wild animals to establish whether animals live longer in captivity or in the wild. A study of more than 50 mammal species found that, in over 80 per cent of cases, zoo animals live longer than their wild counterparts.

Researchers also discovered that “shorter, smaller bodies have lower death rates and fewer diet-related chronic diseases, especially past middle age.” The lifespans of shorter people appear to be longer than their taller counterparts, the paper says.
The desire to live eternally has been around almost as long as humans have been aware of death. Survival is human nature, but is expanding the limits of the human lifespan actually possible? The mean life expectancy for men and women today is about 79 years.
