Longest Living Animals
What Do You Think The Longest Living-Animal Species On The Planet Is? If Your Answer Is The Tortoise, That's A Good Guess! But It's Wrong. Sharks? Still Wrong. Whales? Nope. Okay Fine, I'll Tell You. The Longest Living Animal Is…The Jellyfish!


Well, A Specific Type Of Jellyfish Called Turritopsis Dohrnii. It Has The Strange Ability To Age In Reverse, So Some Even Consider It To Be Immortal, Giving The Species It's Commonly Used Nickname: The “Immortal Jellyfish”. When Exposed To Stress Or Injury, Instead Of Dying, It Transforms Its Mature Adult Cells Into Younger Cells And Ages Backward Into Its Polyp Stage Again. This Jellyfish Is Undeniably Amazing, But There Are Other Animals That Have Incredible Lifespans! So, Let's Take A Look At More Of Nature's Longest-Living Animals!


Who Lives In A Pineapple Under The Sea? Well, No One, Because There Aren't Any Pineapples In The Sea, And Even If There Were, They'd Float. But There Are “Sponges” In The Sea. Most People Often Forget That Sponges Are Actually Animals, Not Plants, And They Can Live For More Than 200 Years. In Fact, There Has Even Been A Sponge That Lived Up To 11,000 Years!


The Ocean “Quahog” Can Live Up To Five Hundred (500) Years. In Fact, A Clam Nicknamed “Ming” Was 507 Years Old. Some Researchers Believe The Quahog’s Secret To A Long Life Is Its Ability To Protect Its Proteins From Damage.

Greenland Shark

A Hundred Years (100 Years) May Be Old For Humans But It's Nothing To “Greenland Sharks”. Growing Only 1 Centimeter Per Year, Greenland Sharks Are Among The Longest Living Vertebrates On Earth. They Can Reach Ages Of 400 Years, With One Actually Living An Estimated 512 Years!

Red Sea Urchins

“Red Sea Urchins” Are The Largest Of All Sea Urchins In The World. These Spiny Creatures Found In British Columbia Can Live For More Than 200 Years. Their Telomeres, A Part Of The Cells That Determine How You Age, Don't Appear To Shorten As They Get Older, As The Ones In Humans Do.

Bowhead Whales

“Bowhead Whales” Have An General Lifespan Of Two Hundred Years, Making Them By Far The Longest Living Marine Mammal On Earth. These Whales Have Very Low Body Temperatures, Which Helps Them Survive For Over Two Centuries.


“Tortoises” Can Easily Live For Over One Hundred Years. A Giant Tortoise Named “Jonathan” Is 187 Years Old. It Is Now Among The World's Oldest Living Terrestrial Animals. In Fact, Some Tortoises Can Even Live To Be 250 Years Old.


“Tuatara” Are Reptiles That Belong To A Lineage Which Existed Before Dinosaurs Which Is Why They’re Called “Living Fossils”. Tuatara Only Live In New Zealand And Grow At Very Slow Rates. While Most Only Lived To Be Around 60 Years Old, Some Have Been Recorded To Live Up To 200 Years.


Most “Koi Fish” Have A Lifespan Of Only 50 Years But A Koi Fish Named Hanako Was Believed To Be 226 Years Old. Her Age Was Measured By Examining Microscopic Rings On Her Scales.

Blind Salamander

The Eyeless Cave “Salamander” Can Live Up To 100 Years. It Has An Unusually Sluggish Metabolism And Takes 15 Years To Mature. It Mates And Lays Eggs Every Twelve Years, And Barely Even Moves Outside Of Seeking Food, Which Helps It Survive For A Century In The Wild. Just Imagine What It Sees In Its 100 Years Of Life! Well, Not Much Because It Doesn't Have Eyes. But Well You Know What I Mean!


The World's Oldest Wild Bird Is A 67-Year-Old “Albatross” Named Wisdom. Albatrosses Tend To Live For About 50 Years. Even At 67 Years Old, Wisdom Is Laying Eggs And Has Hatched 39 In Her Lifetime.

These Creatures All Have Incredibly Long Lifespans For A Variety Of Reasons Showing Just How Diverse Life On Our Planet Truly Is!
