What animal has lived the longest on Earth?

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.

A creature called "hao" is known as a living fossil of paleontology and is still not extinct.

The longest-lived animal - sea turtle Sea turtles appeared on Earth more than 200 million years ago and are known as "living fossils". According to the Guinness Book of World Records, sea turtles can live up to 152 years, making them the most well-deserved longevity among animals. It is precisely because the turtle is a long-lived animal in the ocean, so the people along the road still regard the turtle as a mascot of longevity, just as the mainlanders regard the pine crane as a symbol of longevity, and the people along the coast also regard the turtle as a symbol of longevity, and there is a "10,000-year-old turtle".

At present, there are eight species of sea turtles in the ocean, of which four are produced in China, mainly distributed in Shandong, Fujian, Taiwan, Hainan, Zhejiang and Guangdong coastal areas, and the largest number of groups in China is the green sea turtle. Sea turtles do not mature until they are 20-30 years old, and when the breeding season comes, they return to their "homeland" in groups, no matter how far away, they can find their birthplace and lay their eggs there. If the environment of the birthplace is destroyed, it is at risk of lifelong infertility.

The maximum number of eggs laid by sea turtles can reach about 200, and the minimum number of eggs is more than 90, although the number of eggs is relatively large, but the hatching survival rate is very low. When the baby turtle emerges from its shell, it first has to get out of the sand on its own and then rush to the ocean. From the sand pit to the seashore is full of dangers for baby turtles, some of them fall into the sand pit, and they struggle desperately to get out of the "trap", while some natural predators such as various seabirds are constantly hovering in the air, and they treat these young life as a delicacy.

In the end, it is only a part of the people who will make it to the ocean, and these survivors will grow and develop in the sea, passing on the new cycle of reproduction. How sea turtles find their "home" is still an open question. The spawning period of green sea turtles living along the coast of China is from April to October every year.

At this time, one by one, they quietly climb up to the beach from the sea, dig a pit about 20 centimeters wide and about 50 centimeters deep with their hind limbs, and then start laying eggs. The eggs are white in color and about the size of a ping pong ball. Due to the inconsistent timing of egg maturation, it sometimes takes several times to lay the eggs.

After laying eggs, the hole is blocked with sand, the beach is shining in the sun, the temperature is relatively high, and the eggs are all hatched by natural temperature, and the time varies from 40 to 70 days, generally around 50 days. Turtle eggs are not only hatched by natural temperature, but their sex is also determined by the temperature, with females hatching at high temperatures and males hatching at low temperatures.

Scientists have reached a consensus that the most vigorous of animals is the bear bug.

In the 70s of the 18th century, the Italian zoologist Lazzaro Spallanciani first began to study this invertebrate (millimeter long), which could only be observed under the microscope, and it was he who named this animal "bear bug", which is il

tardigrado, later tardigrada in Latin. Bear insects can only live in humid environments, such as fresh water, wet soil, tree trunks, rocky mountains, and well-watered moss and lichens. Once the water is insufficient, the bear bug enters a state of suspended animation.

It's hard to imagine that 100 years later, a dried bear insect can be resurrected with just a drop of water. In extremely harsh conditions, it can be said that only the bear insect has the strongest vitality. Studies have shown that bear insects that enter a state of suspended animation can withstand freezing of minus 271 for several hours, can also withstand short-term temperatures of minus 150, and can also withstand a large amount of radiation and high pressure.

Japanese scientists have experimented with a bear bug that has entered suspended animation, put it in a sealed container, and then put the container into a high-pressure tank filled with water, gradually increasing the pressure to 600 megapascals, which is equivalent to six times the water pressure of the deepest Mariana Trench. In this way, the vast majority of the bear bugs that participated in the test were subjected to this test, which is simply unimaginable for many animals.

The longest-lived animal in the world, whose blood is more expensive than **, was almost eaten and exterminated by us.

Recently, scientists discovered a "green snake" in the South Pacific, which has lived for 200,000 years and is still in its infancy.

Currently it is the longest-living animal.

Remember to adopt it.

Bacteria live the longest Thank you

Any animal can live for a long time, and animals can live for tens of thousands of years, or even hundreds of thousands of years, when they enter a false sleep (freezing or hibernation), so there is no animal that has lived the longest time, and it can also be said that any animal has lived for the longest time.

Sea turtles can live up to 152 years, making them a well-deserved longevity among animals.

Wang Bajiao can probably live for more than 100 years.

This question may never be answered.

There are creatures in the world that humans have not discovered. Those ancient creatures survived for hundreds of billions of years.

No one knows.

At the beginning of the 21st century, American scientists found a thread-like sea squirt creature in the deep Atlantic Ocean, and every year this creature will produce a thin ring on its tail that can only be observed with a microscope, similar to the growth rings of trees, and scientists have found thousands of thin rings on several labels, and the most one has more than 11,000.

It is a kind of sea surface that lives in water, and German scientists recently discovered that its lifespan is 10,000 years.
