What Animal on Average Lives the Longest
The longest-living animals on World
The animal kingdom boasts some incredibly long lifespans that far exceed the average human's. While humans may have an "absolute limit" of 150 years, this is just a blink of an heart compared with the centuries and millennia that some animals alive through; and some animals can fifty-fifty cease or reverse the aging process birthday.
Although there are very long-living country animals (the oldest tortoise, for case, is well-nigh 190 years old), none of them make this list — the true age champions all alive in h2o. From old to oldest, here are 10 of the longest-living animals in the world today.
1. Bowhead whale: potentially 200+ years one-time
Bowhead whales (Balaena mysticetus) are the longest living mammals. The Chill and subarctic whales' exact lifespan is unknown but stone harpoon tips plant in some harvested individuals bear witness that they comfortably alive over 100 years, and may live more than 200 years, according to the National Oceanic and Atmospheric Administration (NOAA).
The whales take mutations in a gene called ERCC1, which is involved with repairing damaged DNA, that may help protect the whales from cancer, a potential crusade of expiry. Furthermore, another gene, chosen PCNA, has a department that has been duplicated. This factor is involved in cell growth and repair, and the duplication could deadening crumbling, Alive Scientific discipline previously reported.

2. Rougheye rockfish: 200+ years one-time
Rougheye rockfish (Sebastes aleutianus) are ane of the longest living fish and have a maximum lifespan of at to the lowest degree 205 years, according to the Washington Department of Fish and Wild animals. These pinkish or brown fish live in the Pacific Body of water from California to Japan. They grow upwardly to 38 inches (97 centimeters) long and eat other animals such every bit shrimp and smaller fish, according to the Committee on the Condition of Endangered Wildlife in Canada (COSEWIC), an independent advisory console that assesses the status of species threatened with extinction in Canada.

3. Freshwater pearl mussel: 250+ years quondam
Freshwater pearl mussels (Margaritifera margaritifera) are bivalves that filter particles of food from the water. They mainly live in rivers and streams and can be constitute in Europe and North America, including the U.S. and Canada. The oldest known freshwater pearl mussel was 280 years old, according to the World Wildlife Fund (WWF). These invertebrates accept long lifespans cheers to their low metabolism.
Freshwater pearl mussels are an endangered species. Their population is declining due to a diverseness of man-related factors, including damage and changes to the river habitats they depend on, according to the International Union for Conservation of Nature (IUCN).

4. Greenland shark: 272+ years old
Greenland sharks (Somniosus microcephalus) alive deep in the Chill and North Atlantic oceans. They can grow to be 24 anxiety (7.iii meters) long and take a diet that includes a variety of other animals, including fish and marine mammals such as seals, according to the St. Lawrence Shark Observatory in Canada.
A 2016 study of Greenland shark eye tissue, published in the journal Science, estimated that these sharks can have a maximum lifespan of at least 272 years. The biggest shark in that written report was estimated to exist virtually 392 years old, and the researchers suggested that the sharks could mayhap have been as much every bit 512 years old, Alive Science previously reported. The historic period estimates came with a degree of uncertainty, merely fifty-fifty the lowest gauge of 272 years still makes these sharks the longest living vertebrates on Earth.

5. Tubeworm: 300+ years old
Tubeworms are invertebrates that have long lifespans in the cold, stable environs of the deep sea. A 2017 study published in the journal The Science of Nature plant that Escarpia laminata, a species of tubeworm living on the body of water floor in the Gulf of Mexico, regularly lives up to 200 years, and some specimens survive for more than 300 years. Tubeworms have a low decease rate with few natural threats, such as a lack of predators, which has helped them evolve to have such long lifespans.

6. Ocean quahog clam: 500+ years old
Ocean quahog clams (Arctica islandica) inhabit the North Atlantic Bounding main. This saltwater species tin can live even longer than the other bivalve in this list, the freshwater pearl mussels. One ocean quahog clam found off the coast of Iceland in 2006 was 507 years old, according to National Museum Wales in the U.1000. The ancient clam was nicknamed Ming as it was born in 1499 when the Ming Dynasty ruled China (from 1368 to 1644).
7. Black coral: 4,000+ years old
Corals await like colorful, underwater rocks and plants, simply they are actually fabricated upwards of the exoskeletons of invertebrates called polyps. These polyps continually multiply and replace themselves past creating a genetically identical re-create, which over time causes the coral exoskeleton structure to abound bigger and bigger. Corals are therefore fabricated up of multiple identical organisms rather than being a single organism, like Greenland sharks or bounding main quahog clams, so a coral'south lifespan is more of a team try.
Corals can live for hundreds of years or more, but deep-water black corals (Leiopathes sp.) are among the longest-living corals. Black coral specimens plant off the coast of Hawaii have been measured to be 4,265 years old, Live Science previously reported.
8. Glass sponge: 10,000+ years old
Sponges are fabricated upward of colonies of animals, like to corals, and can also alive for thousands of years. Glass sponges are among the longest living sponges on Globe. Members of this group are oft found in the deep ocean and accept skeletons that resemble drinking glass, hence their name, co-ordinate to NOAA. A 2012 study published in the journal Chemical Geology estimated that a glass sponge belonging to the species Monorhaphis chuni was well-nigh 11,000 years old. Other sponge species may be able to live fifty-fifty longer.

9. Turritopsis dohrnii: potentially immortal
Turritopsis dohrnii are called immortal jellyfish because they can potentially live forever. Jellyfish start life as larvae, earlier establishing themselves on the seafloor and transforming into polyps. These polyps then produce free-pond medusas, or jellyfish. Mature Turritopsis dohrnii are special in that they tin can plow back into polyps if they are physically damaged or starving, according to the American Museum of Natural History, and so later return to their jellyfish state.
The jellyfish, which are native to the Mediterranean Ocean, tin repeat this feat of reversing their life cycle multiple times and therefore may never die of old age under the correct conditions, according to the Natural History Museum in London. Turritopsis dohrnii are tiny — less than 0.two inches (4.v millimeters) across — and are eaten by other animals such as fish or may dice by other means, thus preventing them from really achieving immortality.
10. Hydra: too potentially immortal
Hydra is a grouping of pocket-sized invertebrates with soft bodies that look a bit like jellyfish. Like Turritopsis dohrnii, Hydras likewise have the potential to live forever. Hydras don't bear witness signs of deteriorating with historic period, Live Scientific discipline previously reported. These invertebrates are largely made up of stem cells, which continually regenerate through duplication or cloning. Hydras don't alive forever under natural conditions considering of threats similar predators and disease, but without these external threats, they could be immortal.
