What is the longest lived animal? What are the longest lived animals?

The longest-lived creature that can be found in natural science is a microorganism called Methuselah, which lives in sediments and is said to have lived for 2.6 billion years, having been a classmate of the dinosaurs. - 2.6 billion years! God, it's dizzy to think about!

What's even more interesting is that in order to survive, this creature is said to have reduced the rate of its metabolism to a level that even modern instruments cannot detect.

German scientists recently discovered one of the longest-lived organisms to date, a sponge that lives in the Antarctic ocean, with a lifespan of more than 10,000 years. Previously, the longest-lived creature found was the pine tree that grew in the United States, which lived for more than 5,000 years. This sponge is more than two meters long and grows extremely slowly.

Although scientists began studying this sponge 20 years ago, it is difficult to determine its exact lifespan because this sponge does not form growth rings during growth. Recently, scientists at the German Centre for Polar and Marine Research have estimated its lifespan by measuring oxygen consumption.

In nature, the longest-lived creature is the ginkgo tree, which can be more than 3,000 years old. What's even more peculiar is that as a tree species, the ginkgo tree has maintained its characteristics unchanged for more than 200 million years, and the dinosaurs of the same era have long been extinct, but only the ginkgo tree is still full of vitality.

Probably the longest-lived of the animal is the turtle. In 1737, scientists captured a giant tortoise on an island in the Indian Ocean, which was determined to be about 100 years old at the time. The turtle was sent to England and lived for a long time in a zoo, where it still lived in the 20s.

If the zoologist's calculations were correct when the tortoise was captured, the tortoise would have lived for more than 300 years.

Turtles. According to the Guinness Book of World Records, sea turtles can live up to 152 years. The longest-lived was a turtle that died in 1918.

The reptile was captured in 1766, nine years before the outbreak of the American Revolution, when it was already in its adult state. He died 152 years later, at the end of the First World War.

The lighthouse jellyfish (scientific name: turritopsis nutricula) belongs to the class Hydra and is a type of jellyfish. The lighthouse jellyfish has a diameter of about 4 5 mm and is a small jellyfish.

Because of the transparency of the body, the red digestive system can be seen, because their digestive system resembles a lighthouse, hence the name lighthouse jellyfish. Most of them live in tropical seas. It is carnivorous and feeds on plankton, small crustaceans, polychaetes and even small fish.

It turns out that this jellyfish is able to revert from the stage of sexual maturity to the larval stage of the creature, as if it were rejuvenated. Ordinary jellyfish die after sexual reproduction, but lighthouse jellyfish can return to their juvenile state again, just like the Eight Desolations and Liuhe Solitude Martial Arts practiced by Tianshan Tong Grandma in "Tianlong Babu". I don't know if the old man Jin Yong knew that there was a lighthouse jellyfish in the world when he wrote about Tianshan Tong's grandmother.

There was a shark that survived from the Ming Dynasty to modern times.
