Humans don’t actually live that long, with an average life span of about 77 years, making 100 an unusually long lifespan.According to a new study by a team of researchers from roswell Park Cancer Research Center in the United States and A Singaporean biotech company, the limit is about 150 years.150 years is a relatively high life span in the animal kingdom.Although humans have an upper limit of a century and a half, there are plenty of other animals that outlive us.Today, Imagination brings you the top 10 longest-living animals in the world.Old rules, please readers master move your rich little hands, give the author a free praise and attention, thank you.Okay, number ten, red sea urchin.Sea urchins are a rare delicacy for seafood lovers.So did you know that sea urchins are actually one of the longest-lived animals in the world.As one of the oldest creatures on earth, sea urchins are legendary.Sea urchins have existed on Earth for more than 570 million years.They are widely distributed and very diverse. There are more than 7,000 species of sea urchin fossils discovered by human beings alone, and there are more than 900 species of sea urchins that are not extinct at present.Sea urchins are so powerful because of their longevity and special physiological mechanisms.Marine zoologist Thomas Albert of Oregon State University and his team have used carbon-14 radiometry to measure the life of sea urchins.They found that red sea urchins, living in shallow waters off the Pacific coast from Alaska to California, can live up to 200 years.And unlike humans, red urchins are not “old”;Even when you’re over 100, you can still have the same reproductive drive and energy that you had when you were young.All right, number nine, Galapagos tortoise.As the saying goes, “a thousand years of bastard, ten thousand years of turtle.”The first thing we notice about turtles is their longevity.But in fact, the life of the tortoise in the animal kingdom, is not the most top that group.Even the longest-lived tortoise was only ninth on the list.Galapagos tortoises are the largest tortoises and the longest-lived tortoises.They are 1.2 meters long and weigh about 300 kilograms, due to their slow movement.Galapagos tortoises spend eight to nine hours a day just foraging for food and two to three hours basking in the sun.It may be that this laid-back lifestyle makes Galapagos tortoises grow very slowly, taking 25 to 40 years to reach full maturity, but it also gives them a long life span.In 2006, Adevita, a giant tortoise at the Kolkata Zoo in India, died at the age of 255.The tortoise is believed to have been brought home from the Galapagos islands by British sailors in 1875 and given to the East India Company as a gift.Advita died after more than 100 years at the zoo and three keepers.No. 8 bowhead whale, an Arctic and subarctic whale, is about 21 meters long and weighs about 100 tons.In order to resist the cold, their body fat is fully 70 cm.Bowhead whales are an exception to the stereotype that large animals don’t live long.They are the world’s longest-living whales, as well as the longest-living mammals.In 2007, researchers captured a bowhead whale off the coast of Alaska with a harpoon head made between 1879 and 1885 around its neck.If the unfortunate child had been harpooned at birth, it would have lived at least 122 years at the time of capture.Later, the researchers captured additional bowhead whale samples, and using technical measurements, estimated that another captured bowhead whale lived about 211 years old.And 211 years is not the limit of bowhead whale lifespan, just the highest ever observed.According to researchers at Australia’s Commonwealth Scientific and Industrial Research Organisation, the genome sequence shows that bowhead whales have a limit life span of about 268 years.Ok, number seven is the tube worm, which lives for about 300 years.Tube worms, also known as tube worms, are relatively large animals, up to 1.2 meters long, shaped like a tube, hence the name.Although tube worms are animals, they don’t have mouths or digestive systems.Survival is entirely dependent on “symbiotic bacteria” in the body.The symbiotic bacteria obtain sulfur ions from the hydrothermal fluid of the ocean and oxygen from the seawater to synthesize the organic matter necessary for tube worms to survive.Despite the fact that worms depend on other people for their survival, their lifespan is ridiculously long.Scientists found tube worms deep in the Gulf of Mexico, some of which may be 250 to 300 years old, in a study published in NaturalScience in 2017.Okay, number six, Greenland sleeping shark.Living mainly in the depths of the Arctic and North Atlantic oceans, the Greenland sleeping shark is one of the largest sharks alive, reaching up to seven meters in length and weighing around 1,000 kilograms.Living in icy waters, Greenland sleeping sharks grow very slowly, only 3 centimeters a year, and need to reach sexual maturity of about 4 meters, which takes about 150 years.But the good news is that Greenland sleeping sharks live long enough to reproduce.Between 2010 and 2013, Marine biologist John Stephenson of the University of Copenhagen in Denmark and his team aged 28 captive Greenland sleeping sharks and found that one of them lived to be 392 years old.But that number is off by about 120 years, so this Greenland sleeping shark could have lived for as little as 272 years or as long as 512 years.Fifth, arctic quahog clam.The arctic quahog is an animal that lives in the depths of the sea and has an extremely long life span.In 2006, British researchers collected 200 arctic quaams off the coast of Iceland to investigate changes in the Marine environment and climate over the past several thousand years.The researchers found that one of the arctic quahog species may have lived as long as 407 years.But when scientists tried to pry open the shell and determine its exact age, they accidentally killed it.Unfortunately, the arctic clam lived to be 507 years old after careful study.For some reason, it took until Nov. 13, 2013, to publish the results of the study.The researchers named the clam Ming because it existed in China during the Ming Dynasty.Okay, fourth place, black horn coral.Many people mistakenly think corals are not animals because they look like rocks or plants.Coral is essentially an animal made from the exoskeleton of an invertebrate polyp.When the polyp is born, it is just a small floating larva, and at that time it can swim around.Once they find the right place, they settle on the seafloor and develop into coral.In addition, polyps can reproduce by sprouting from their original bodies in the same way that plants do.This reproductive process, similar to sprouting plants, gives corals a long life span.In 2009, researchers discovered the world’s oldest living black horned coral, off the coast of Hawaii.According to the study, this black horn coral can live up to 4,265 years.Third on the list is the glass sponge.This sponge, not our dishwashing sponge, is one of the oldest primitive multicellular animals on Earth, having appeared in the earth’s oceans 600 million years ago.Sponges are similar to corals in that although they are animals, they are fixed to the bottom of the sea like plants.And sponges have no head, mouth, digestive system or nervous system. The main components of their cells are calcium carbonate or silicon carbonate and a lot of collagen.Yet sponges, with their primitive and simple physiologies, are among the world’s longest-lived animals.Researchers at the National Oceanic and Atmospheric Administration in the United States have worked on a “glass sponge.”Glass sponges live mainly in the deep sea and get their name because their bones resemble glass.In 2012, a study published in the journal Aging Research Reviews reported finding a glass sponge that had lived for about 11,000 years.You know, our civilization is only about 6,000 years old.In other words, the glass sponge existed when our ancestors were primitive.In fact, many sponges can live for thousands of years, but in order to show off other long-lived animals, there is only one sponge on the list.All right, then we’re tied for first place with hydra and turritopsis, two animals that can theoretically live forever.Start with the turritopsis nutricula, an animal that could theoretically achieve “immortality,” according to a 2010 article published in Nature & Science.The researchers say that under certain conditions, turritopsis can “reverse growth”, changing from a mature polyp to a new polyp.In theory, as long as this cycle continues, turritopsis could stay young forever.However, many experts saw the article and pointed out loopholes.First, there is no scientific evidence that the jellyfish and polyp status of turritopsis turritopsis are related to adult and juvenile bodies.The difference between them is more like life status than age status.Second, all the current academic studies on turritopsis do not clearly explain whether the morphologies of turritopsis are infinite.Therefore, turritopsis’ immortality is only a theory.And then there’s the polyp, a type of coelenterate that lives mainly in fresh water, somewhere between a jellyfish and a coral.Hydra are very tiny, only a few millimeters long.But they, like the turritopsis nutricula, are theoretically immortal.In 1988, a team of researchers from Pomona College in the United States studied the aging of hydra, conducting two observational experiments over a total of 12 years.After observation, it was found that the reproductive capacity of the polyp did not deteriorate over time, and there were no obvious signs of aging.Bizarre as it may seem, the researchers concluded that polyps “do not age.”The reason why polyps live forever is that their bodies are mostly made up of stem cells.Stem cells are very primitive cells with a strong ability to self-renew and divide, and can produce daughter cells with phenotype and genotype exactly the same as their own.In simple terms, as a polyp ages, it splits and creates a new “part” that replaces the old part and keeps the body functioning in a youthful and healthy state.So a polyp, which is mostly made up of stem cells, can’t theoretically die.Why theoretically?For the same reason that turritopsis, we don’t know if the hydra’s self-repair, self-renewal, is infinite.
