Top 10 Oldest Animal in the World | Longest-Living Organisms: The World’s Oldest Known Animals that are currently living, Record holders, such as the most long-lived human, Jeanne Calment, and the most long-lived domestic cat, Creme Puff. We have collected some list of the Oldest Animal in the World and longest-living organisms,

1. The World’s Oldest (Known) Animal

Ming the clam lived a long life with age 507 years old, if somewhat unremarkable, life. But, he could have lived even longer if scientists hadn’t discovered him. Regrettably, their calculations of Ming’s age weren’t likely without breaking the clam’s shell, so researchers didn’t discern they were in possession of what was possibly the world’s oldest living animal – until they had already killed it.

The only thing came out of Ming’s demise is that his shell can provide scientists with unique insights into the varieties of sea temperatures over the last 500 years and can unlock the secret to aging.

2. World’s Oldest Tortoise

Tortoises are known for their longevity. In India, a tortoise living in Alipore Zoo set a record that won’t soon be broken surviving for 250 years. To put things in view, that’s older than the government of the United States of America.

In 1700, Adwaita’s life began and when he was caught in the Seychelles Islands before being given to Robert Clive who is the British general of the East India Company. He kept Adwaita as a pet before it was donated to the zoo in 1875. For more than 125 years, he lived in the same aquarium, until it passed away in 2006. Adwaita’s shell was then carbon dated to confirm and count his age.

3. World’s Oldest Living Land Animal

There are corals known to live for thousands of years, bowhead whales are calculated to live for centuries, but land animals infrequently have such long lifespans. The current record holder for the longest currently living terrestrial animal goes to a tortoise named Jonathan.

In 1882, a tortoise was brought from the Seychelles Island and continued to live at the official residence at Governor of Saint Helena.  At 182 years old, it’s unlikely any humans will beat his record anytime soon.

4. World’s Oldest Cat

The world’s oldest living cat, Tiffany Two had died earlier in 2015 at the age of 27, and Guinness still hasn’t verified a follower for the most past living cat title. But 27 years is nothing compared to the oldest cat of all time, who lived to be 38. The most long-lived domestic cat, Creme Puff lived in Austin, TX with her owner, Jake Perry, and another cat named Granpa.

At the time of Puff’s dead, Granpa held the world’s oldest cat title, but once he lived past 34 years, she took the title. Since two of the world’s oldest cats related to the same person, many claim Perry’s unusual choices of foods which includes bacon, eggs, asparagus and broccoli are what helped the cat’s felines survive so long.

5. World’s Oldest Dog

There are no confirmed reports of a dog living to the age of 30 so far, but Max came darn close at 29 years and 282 days. The cute beagle/terrier mix was born in 1983 and adopted soon after by his long-term owner, Janelle Derouen. Veterinary department records proved Derouen’s request, and up to now, Max holds the title for world’s oldest dog.

6. World’s Oldest Horse

The World’s Oldest Horse born in 1760 named as Old Billy lived to an impressive 62 years old, more than twice as long as the normal horse’s lifespan. The horse didn’t live a life of leisure either and spent most of his life as a barge horse. As he started to age, his back was bent, and his osseins began swelling through his skin. But, he became a bit of a local celebrity, and he was portrayed in a lithograph at the age of 60.

He was said to be a cob horse and had a brown coat with a unique white blaze. After Billy’s death, his skull was split in two, with one-half taxidermied and the other left bare. The two halves of billy’s skull are now on exhibition in the Manchester Museum and the Cecil Higgins Art Gallery & Bedford Museum.

7. World’s Oldest Lobster

In 2008, a Fishermen from the coast of Newfoundland captured George, the Lobster. He was sold to City Crab and Seafood for $100 thanks to his impressive size for 20 pounds. Keith Valenti, a restaurant’ manager, says George was never even meant to be eaten but worked as a mascot and pet, the lobster’s huge size attracted curious visitants to the restaurant. George only lived at the restaurant for ten days before protesters from PETA satisfied City Crab to release him back into the wild.

PETA took particular interest in George’s freedom because a lobster size correlates to his age, and, at 20 pounds, they considered the lobster to be 140 years old. Since he was released into the wild, it’s impossible to know if he’s still alive and hitting.

8. World’s Oldest Elephant

The Average lifespan of an elephant is normally 50 years. An Elephant named Lin Wang had survived to the ripe old age of 86. During World War II, the Japanese used elephants to transport supplies and pull large cannon pieces. In 1943, Lin Wang was captured and used by a Japanese camp. They used it to support the Chinese Expeditionary Force for the support of the war.

In 1952, Lin Wang was donated to the Taipei Zoo, and he was introduced to his lifelong partner, Malan. Wang became the most famous attraction at the zoo and was fondly called “Grandpa Lin Wang” by visitors. He died in 2003, and his memorial service lasted for weeks and attracted tens of thousands of visitors.

9. World’s Oldest Lizard

The tuatara or Lizard is known for its longevity, usually lives over 100 years. The oldest documented tuarara is a resident of the Southland Museum of New Zealand. He is currently 117 years old and recently fathered his first brood of babies at the tender age of 111.
