What animal lives the longest on land?
The animal that lives the longest on land includes the Aldabra tortoise that has a lifespan of 250 years. Adwaita, one of the giant tortoises, died in the Alipore Zoological Garden of Calcutta. Among the 4 tortoises, brought to India by British sailors from the Seychelle islands as a gift for Lord Robert Clive of the East India Company, Adwaita lived the longest and made history. Weighing 250 kg (551 lb), Adwaita was a loner, with no signs of his progeny. He lived on a diet of wheat bran, carrots, lettuce, soaked gram (chickpea), bread, grass, and salt.
He had a tremendous lifespan which made him the longest living species in the animal kingdom. Adwaita lived in captivity and recorded to be the longest surviving animal on the land.
His shell cracked in the year 2005 and the wound developed beneath the shell. The wound caught an infection and made him sick. Finally, in the year 2006, the species died due to illness. However, Adwaita had a brilliant lifespan and showed good signs of living during his whole lifetime.
Here is a list of some more species who have survived longer on land. Let’s have a look and grab some knowledge about the longest sustaining creatures:
Born in 1832, the tortoise still fights for his survival and will turn 188 in the year 2020. Tortoise is one of the animal which lives the longest among other species. This tortoise belongs to the breed of Seychelles Giant Tortoise. Jonathan has a highly nutritional diet and is fed with apples, carrots, cucumber, banana and guava that make him stronger and tougher.
Geoduck has a typical lifespan of 160 years. However, some them have survived the battle for even more. They are the natives to the west coast of North America. They are one of the largest burrowing clams. Like other clams, which mostly have shells, these species have a small shell compared to their soft bodies, which they cannot retract into the shell.
This species is another beautiful creature that typically lives for 60-100 years. However, some of them have been found to live for about 100 years of age. These are spiny reptiles that have a similar appearance as lizards. Tuataras enjoy cool weather whereas lizards like it warm. They are healthy creatures, generally with males larger than females.
Albatross survive up to the age of 50 years or more. The longest living albatross in the US and one of the world’s oldest known wild birds is an Albatross named Wisdom.
Wisdom recorded to live the age of 68 years in captivity and broke the record as the longest surviving bird of its species. The bird continued to lay down eggs for during her old age also.
The oldest living elephants:
The average lifespan of an elephant in the mid-50s, however, some have fought the battle of making it to the 80s also. Elephants are natives to Africa and are the largest mammals. They have a giant body and heavy creatures. Besides, they also have a long gestation period. They show good signs of survival and some of these beasts even live till a century.
What animal lives the longest in the wild?
There are a wide number of animals ou there in the wild. Different habitats have determined the age of different species of the wild. For example, it has been observed that the animals living in aquatic habitat live for thousands and thousands of years.
On the other hand, the life of the flight is also amazing. As these species can migrate and settle around in remote regions where they can find comfort, they tend to live a little longer. Now let’s have a brief look on different species sustaining in distinct habitats:
Marine animals living the longest in the wild:
|Bowhead Whales||Typical Lifespan: 211 years|
|Rough Rockfish||Typical Lifespan: 205 years|

|Giant Barrel Sponge||2300 years|
|Ocean Quahog Clam||Typical Lifespan: 400 years, Exceptions: 507 years|
|Tube worms||250 years|
Land animals living the longest in the wild:
|Geoduck||Typical Lifespan: 160 years|
|Elephants||Typical Lifespan: 50 years, Exceptions: 80 years|
|Tuatara||Typical Lifespan: 60-70 years, Exception: 100 years|

Birds having the longest lifespan in the wild:
|Layson Albatross||+65 and currently alive|
|Arctic Tern||34 years|
|Brown Pelican||27 years|
|Great Horned Owl||27 years|
|Mute Swan||26 years|
What animal lives the longest in captivity?
Many species are kept in a zoo or as a pet. It has been discovered that the species living in captivity tend to live longer than the animals living in the wild. Let’s have a close look at the species, who have sustained in captivity for a long time.
Adwaita, an Aldabra Giant Tortoise
lived the longest age of 225 and died in 2006 in Alipore Zoo, Kolkata. He is recorded as one of the longest living tortoises of the animal kingdom.
Adwaita was a solitary animal with no records of his progeny. He weighed around 250kgs and mostly fed on wheat bran, carrots, lettuce, soaked gram, bread, grass, and salt.
His death came upon when his shell broke in the year 2005 and was wounded beneath the shell. Eventually, the wound caught an infection and he died in the year 2006.
Jonathan is still fighting the battle of survival:
Jonathan lives on the grounds of Plantation House, the residence of the Governor of St Helena.
This tortoise belongs to the breed of Seychelles Giant Tortoise. Born in 1832, the tortoise is still fighting for his survival in captivity and will turn 188 in the year 2020. Jonathan has a highly nutritional diet and is fed with apples, carrots, cucumber, banana and guava that make him stronger and tougher.
The oldest gorilla survived 61:
Western lowland gorillas are a subspecies native to Congo Basin and are most widespread among all the species of the gorilla.
Their lifespan in the wild ranges from 30-40years while in captivity they can survive for about 50 years or beyond.
Colo survived the battle and finally died at the age of 61 making history. Colo is recorded to be the longest living zoo-born gorilla.
The oldest living elephants:
The average lifespan of an elephant in the mid-50s, which makes them one of the animal which lives the longest on land. However, some have fought the battle of making it to the 80s also.
- Lin Wang, an Asian Elephant died at the age of 86. He made a Guinness record of making it to the longest living elephant in captivity.
- Dakshyani, an elephant in the Chengallur Mahadeva Temple of Kerala also died at the age of 86 and recorded one of the longest living elephant species.
Oldest cockatoo is over 100 years old
Cockatoo belongs to the parrot subfamily a Cacatuidae. Their average lifespan is 60, but some of them have hit centuries and survived for longer periods.
- Fred, a sulfur crested Cockatoo in Tasmania, Australia is now 104.
- Another Australian sulfur-crested cockatoo known as Rocky Benett lived 120 years of age until 1916.
- Another cockatoo named Cookie is also famous for its longevity and recorded to live for 83 years at Brookfield Zoo outside Chicago.
Tigers have an age of 10-15 years in the wild while in captivity they live 15-20 years. An Australian Tiger made the record of 26 to live in captivity. Most of the tigers die before the age of one. The infant mortality rate of tigers is 50%. Some tigers have made it a little far too. Tigers are the species of wild. But for human needs, they are also hunted down and their population is falling at a constant rate. These tigers need to be protected or they would soon fall under the category of endangered.
Why do Animals living in captivity live longer than wild?
A deep analysis of 60 species has proved that an animal who lives in captivity tend to live for a longer run that out there in the wild.
The animals face the challenges of predation, being hunted down, in search of food and shelter and critical weather conditions. Whereas in captivity, these species are given certain special advantages taken care of/.
After marking a record of various mammalians like tiger, big cats, reindeer, and African Buffalos, researchers conclude that 80% of animals live longer in captivity that battling for their lives out there in the wild.
Fair compassion was made based on 4 parameters of survival: longevity, baseline mortality, the onset of senescence and rate of senescence between animals in captivity and the wild. They concluded that small prey mammal benefitted from captivity rather than living in the wild. It also states that carnivores longevity increase in the zoo.
Some studies have also shown that these animals might face behavioural abnormalities by living in captivity. In the wild, these animals are free to roam around while in captivity they are bounded and some of them live a life of solitude. Therefore psychological changes are a challenge but eventually, their life becomes easier in the captivity.
Every species fight their battle of survival in different ways. Besides, lots of external factors also influence their survival on the specific ecosystem. They are exposed to predators, bad weather conditions, fight for their food and shelter. Everything is directly proportional to their rate of survival.
Human interference also leads to their destruction of habitat as a result of which many species lose their home and eventually die. Natural disasters like forest fires, landslides, volcanic eruptions can also lead to the destruction of species and their habitat.
For example, the recent Australian fires were brutal. Lots of species were the victims of these fires.
However, lots of species strive for the battle of surviving it to the longest. Bowhead whales are the species who can last for 200 years.
We also saw that many animals live better in captivity rather in the wild. As they are not exposed to the challenges in the wild, their longevity increases.
Therefore, apart from what these species face to survive, a lot of factors concerned with humans could be taken care off and initiatives should be taken by each to help these animals fight the battle of sustaining.
Cutting off the power supply, using footsteps for covering shorter distances, planting trees are some of the steps that would contribute to long survival rates
