What has the longest lifespan and what has the shortest lifespan?

Human life expectancy is the longest, and animals will be killed by humans sooner rather than later! The longest-lived animal in the dream is. Mythical beasts and children!

Turtle, if you're asking about a dream, there's never the longest, and it's okay to eat a bean or something when you're dying.

The lifespan of snakes is also very long.

Time, ticking and ticking. We have only existed on Earth for a very short period of time. Even the human species itself is quite young.

But longevity is a relative point of view: there are creatures on Earth that live much shorter than humans, and some outlive all of us.

What says mayflies are the shortest-lived insects in the world?

Mayflies are arguably the shortest-lived insects. It does not live for more than a day from the time it becomes an adult (at birth) and usually dies within a few hours. However, after mating, the adults lay their eggs in the water, but the larvae take 1 to 3 years in the water to become sub-adults, and the sub-adults crawl out of the water and shed their skin before becoming mayfly adults.

The reason for the ephemera's short life is mainly that its mouth has degenerated and cannot eat.

What animal has the shortest lifespan? The lifespan of invertebrate paramecium and amoeba is calculated in days and nights or hours, and their lifespan is at most one day and night. Among vertebrates, the shortest-lived is the mudskipper, a small fish that is only a few centimeters long and has a lifespan of less than a year.

The lifespan of insects is very special, the adult lifespan of the common fly is 15-25 days, and if its larval and pupal stages are included, its lifespan is 25-70 days. The May-old beetle can live for 1 2 months as an adult, but its larvae can live for 3 to 4 years in the soil. Worker bees born in spring and summer can only live for 6 weeks, while those born in autumn live for 6 months, and the queen bee lives much longer, it can live for 5 years.

The lighthouse jellyfish is the only "undead" creature on Earth The only "undead creature" rejuvenates after adulthood Of all life on Earth, there is one thing that no kind of life can escape, and that is death. The oldest tree on Earth is an American foxtail pine, nicknamed "Prometheus," which was estimated to be 5,000 years old before it fell in 1964. In Siberia, the Canadian tundra and Antarctica, there are also bacteria that are about 500,000 years old, according to scientists.

However, there is no creature on earth that can compare with the "immortal jellyfish", this sea creature called the lighthouse jellyfish has the ability to "rejuvenate", and it can be said that it holds the mystery of immortality. This lighthouse jellyfish is about 4 to 5 mm long. Normally, jellyfish die after breeding to the next generation, but lighthouse jellyfish can "rejuvenate" after sexual maturity, return to the larval state, and then continue to grow and start another life course.

Theoretically, lighthouse jellyfish could carry out this cycle of "rejuvenation" without indefiniteness in order to achieve immortality – first, of course, they must be prevented from being eaten by their predators in the ocean.

For some species, living to 100 years is far from an advanced age. The Odysseus takes you on a tour of the world's longest-lived animals today.

The longest-lived creatures in the world are trees. The longest-lived of trees are trees, followed by shrubs and vines. Arbor.

Depending on the species, the length of life varies greatly. In general, conifers live longer than broad-leaved trees. Pine, spruce and larch have a long lifespan.

250-400 years, Korean pine up to 3000 years, giant sequoia up to 4000 years Recently, scientists have also found that sea anemones live much longer than turtles, corals and other species that live for hundreds of years, and are the world's longest-lived marine animals. Three sea anemones harvested from the deep sea were measured using the radioisotope carbon-14 technique, and their ages were found to be 1500 2100 years old. The oldest surviving pine tree is over 4,030 years old.

German scientists recently discovered one of the longest-lived animals 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.

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.

The thousand-year-old king and the 10,000-year-old turtle are, of course, turtles.

The fact that it has the longest life span in the world is something that many people yearn for. Therefore, since ancient times, some people have been obsessed with the pursuit of immortality. SoIn reality, the world's longest-lived creature has been discovered in the sea, and they have long mastered the secret of rejuvenation and achieved immortality, and this creature is the lighthouse jellyfish.

The lighthouse jellyfish is a small jellyfish with a bell-shaped body and a diameter of only about 4 5 mm. The body is transparent, and the red digestive system can be seen at a glance. Their biological characteristics are surprising, that is, they are able to differentiate and metastasize into larvae again after sexual maturity.

In layman's terms, it is what we think has the ability to reverse time and rejuvenate.

Scientists in the last century inadvertently discovered that the life course of the lighthouse jellyfish can jump out of the link of death, that is, through cell differentiation, continue to develop from juvenile to adult, and then from adulthood to the initial stage of juvenile, and such a reincarnation process can be completed in 30 days. Through the process of rebirth, one jellyfish can become hundreds of identical jellyfish. This would explain why the world's oceans are full of lighthouse jellyfish with almost identical genetic arrangements.

Normally, jellyfish fertilized eggs combine and become floating larvae floating in the water, and only become polyps after finding an object to attach to. Then, after experiencing the two states of transverse fission and saucer-shaped larvae, it is the jellyfish body, that is, it will die after completing the reproductive task. This is the life trajectory of the common jellyfish, but the lighthouse jellyfish is very different, it has the ability to return to the polyp form after the stage of sexual maturity.

However, this reverse growth initiation is conditional, not at any time, and must occur when they encounter starvation, physical damage, or other sudden crises, that is, when the situation is very urgent.

Logically, the lighthouse jellyfish can constantly transform between the jellyfish type and the polyp type, so as to obtain an infinite lifespan and achieve the desired state of longevity. But the cyclic process of the lighthouse jellyfish from adult to juvenile is essentially the reexpression of muscle cells in the body. What needs to be discussed now is, when all the old cells are replaced by new ones, is the lighthouse jellyfish still the same jellyfish that used to be?

What is the longest-lived creature in the world?

Bowhead whales, bowhead whales are the longest-lived mammals found so far, along with lighthouse jellyfish, Antarctica sponges, and more.

The longest-lived creature in the world is the turtle, because there is a saying that the thousand-year-old king is 80,000 years old, so the turtle has the longest lifespan.

Lighthouse jellyfish. Lighthouse jellyfish can reproduce asexually from polyps and are the only known rejuvenating creature. The lighthouse jellyfish is also known as the immortal jellyfish.

It's about living things, not about animals. The life span of fungi in the state of spores exceeds that of animals, and the life span of plants far exceeds that of animals.
