7 Animals With The Longest Life In The World, Some Live Forever

JAKARTA - In this world there are animals that live far beyond the human age limit. If humans are estimated to only be able to live a maximum of about 150 years, that life is only an instant of the eye compared to hundreds to thousands of years that some animals have achieved. There are even animals that live forever.

Most of these animals live in the sea, especially at a steady depth of temperature, so their aging process is very slow. Here are 7 animals that have a long life, as reported by the Live Science page.

1. Hydra Potentially Lives Eternal

Hydra is a small, soft invertebrate that looks like a miniANGle. His body consists mostly of punca cells (stem cells) that continue to regenerate through doubling or cloning, so they do not experience aging like living things in general.

They can indeed die in the wild due to predators or diseases, but without these threats, hydra can continue to regenerate indefinitely.

"They don't seem to age, so potentially they are eternal," said Daniel Mart Mariez, professor of biology at Pomona College, California, who discovered this fact.

2. Turripsis dynasis dohrnii Potentially Living Eternally

Thiscipal species is nicknamed immoral jellyfish' because it is able to reverse its life cycle. After becoming an adult cult, T. dohrnii can return to polyp form if injured or starving, then return to being a cultivator.

This process can be repeated many times so that theoretically they will not die from old age. However, in the wild, they can still die from predators or because of other factors.

3. Glass Sponsors More than 10 Thousand Years

Glass spons live in the deep sea and have a skeleton that resembles glass. They consist of colonies of small animals such as corals.

A 2012 study in Chemical Geology estimated that one of its species, MonorhaphisXini, is about 11 thousand years old. Several other species may be even older.

4. Karang Hitam More than 4,000 Years

Although it looks like a rock or a marine plant, corals are a collection of small animals called polyps that double themselves and form a hard skeleton.

Deep-sea black Karang is among the longest. Specimens found in Hawaii were 4,265 years old based on radiocarbon dating.

5. Ocean Quahog Shell Over 500 Years

Arctica islandica shells that live in the North Atlantic Ocean can grow very slowly due to low metabolism in cold waters. In 2006, a shell was found off the coast of Iceland aged 507 years. This shell is dubbed Ming because it was born in 1499, during the Ming Dynasty in China.

"It could be that there are those older than 507 years, it's just that they haven't been found yet," Anna Holmes wrote, curator at the Wales National Museum.

6. Tubeworms 300 Years More

Tubeworms live on the seabed and get nutrients from bacteria that convert chemicals into sugar.

Escarpia laminata species in the Gulf of Mexico are known to live an average of 200 years, some even exceeding 300 years. This is possible because their metabolism is very slow and has almost no predators.

7. Greenland Shark More than 272 Years

The Greenland Shark (Somniosus microcephalus) is a vertebrate with the longest lifespan ever recorded. Living in deep waters of the Arctic and North Atlantic, this shark can grow up to 7.3 meters.

Research in 2016 estimates the maximum age is at least 272, even one individual is estimated to be 392 years old and possibly 512 years old.

"The lowest estimate alone has made this shark vertebrate with the longest life on Earth," said Julius Nielsen of the Greenland Institute of Natural Resources.
