Albert Einstein once said that time and space do not actually exist, this is just a fantasy and definition of man, the concept of time in our minds is a few hands on the clock, the calendar on the day and the moon change. The nature of time is not clear to everyone, including many scholars who are now studying this topic. That is most inseparable from time, life span! Next, Bao Ge will take you to see the ranking of the length of life of the world's creatures! #全能创作家 #
Twenty-sixth, bacteria, as a single-celled organism, a cell divides into two, then the original cell does not exist, so we can think of this reproduction time as lifespan, the shortest bacterial division time is about thirty minutes, and thirty minutes we can see as the average lifespan of bacteria, so in theory, bacteria are the shortest lifespan.
The twenty-fifth, ephemera, as the shortest lifespan of insects, ephemera twilight death, the shortest life cycle is less than 24 hours, in the spring and summer of each year, on the river surface can see a large number of ephemeral mating and giving birth, like snowflakes flying, very spectacular. And the meaning of their short life lies in the continuation of the species.
Twenty-fourth, male mosquitoes, male mosquitoes in general conditions, and female mosquitoes mating seven to eight days after death, one thing to say is that the blood suckers only female mosquitoes, female mosquitoes stimulate the brain through blood sucking and then promote the development of the ovaries, at the same time, the rich protein contained in the blood is also conducive to the development of eggs, under natural conditions, can survive for about a month.
Twenty-third, flies, flies lifespan is generally between one and two months, their life and temperature, food, humidity and other factors are closely related, especially temperature, and humans, the temperature of the low new city metabolism declines, so the temperature is lower than ten degrees when the flies can hardly move, we in the winter, is rare to see their shadow, don't look at their short lifespan, they only need to mate once to finally produce eggs, just like hanging, no wonder when the weather is hot, how to fight flies can not finish.
The twenty-second, the dragonfly, is the most eye-eyed insect in the world, which makes them extremely good at seeing and is a rare master of catching insects. Dragonflies generally live about four months, and among insects, this lifespan is already very long.
Twenty-first, bed bugs, bed bugs must be no stranger to everyone, as human parasites they will suck blood after humans fall asleep, their average life expectancy is about six months, even if they do not eat completely can survive for nearly 70 days, if the cockroach is called Xiao Qiang, then it is called Big Qiang.
Twentieth, mosquito-eating fish, there is a freshwater fish called mosquito-eating fish in the United States, which has only a two-year lifespan, and captive mosquito-eating fish have a longer lifespan than wild mosquito-eating fish.
Nineteenth, seahorse, the average lifespan of the seahorse is only three or four years, specifically, different types and qualities of seahorse life are different, smaller seahorse is relatively shorter, about a year or so, the larger seahorse has about four to five years.
The eighteenth, the guinea pig, also known as the guinea pig, with its cute appearance, has captured the love of many humans, with an average lifespan of about four or five years, has become extinct in the wild, and is currently scattered around the world as a pet.
Seventeenth, chickens, yes, the chicken friends probably have an understanding, the average life expectancy of chickens in the natural state is six to seven years, according to relevant records, the world's longest-lived chicken is currently from Alabama, the United States, a hen, survived for 14 years, can be described as the king of chickens.
Sixteenth, dogs, of course, very common mammals, no more than Pogo, the average lifespan of large dogs is nine to twelve years, and small dogs are twelve to thirteen years.
Fifteenth, cats, presumably all shovelers should have some understanding, under normal circumstances, the life of cats is about thirteen to fifteen years, and some cats will live to about twenty years, how old have you ever seen the oldest cat?
Fourteenth, tiger, the average lifespan of the mountain king is twenty to twenty-five years, the captive tigers in the zoo are generally longer than the lifespan of wild tigers, the New York Zoo once had an Indian female tiger live for 18 years, six months and 24 days, and the Beijing Zoo also has a Siberian tiger that lives longer, there are 21 years, theoretically, the average life expectancy of tigers should be about thirty years old.
Thirteenth, naked mole rat, a mammal, although the appearance is not very pleasing, but it is a cold-blooded animal with no pain at all, the average life expectancy can reach thirty years, compared with other rodents, naked mole rat life expectancy is about ten times higher, it is worth mentioning that their body never appears cancer and other physical deterioration reactions, even if they die, they can still reproduce, humans have most of the genes and naked mole rats are the same, Therefore, many researchers continue to explore the mystery of the longevity of naked mole rats in order to benefit humans.
Twelfth, horse, the world's horse breeds have nearly 200 kinds, due to the current development of modern science and technology, horses in human life does not play a big role, so in real life, rarely can see the figure of horses, of course, some areas have horse farms or something, this of course can be seen. The average lifespan of a horse can reach thirty to thirty-five years, and the longest can reach sixty years.
Eleventh, parrots, parrot lifespan is also distinguished by body size, small parrots lifespan of about eight to twenty years old, large parrots have a lifespan of fifty to ninety years, and parrots with a medium size or so are basically in the middle of this age range.
Tenth place, koi, this is certainly not unfamiliar to everyone, generally every New Year's Holiday, or when the exam is promoted, everyone will be in the circle of friends by forwarding koi to seek blessings, koi can survive for sixty to seventy years under normal conditions, records show that there are also people who have raised old koi that are more than 200 years old.
The ninth, the elephant, is currently the largest mammal on the earth's land, as a social animal under general conditions of life expectancy can reach about seventy years old.
Eighth, human beings, in different eras, human life expectancy is also different, compared to the previous ancient times, everyone is not enough to eat and wear warm, and there are various diseases plagued, resulting in the average life expectancy of ancient people is only about 25 years old, until the beginning of the twentieth century, the average life expectancy of human beings has reached sixty years old, some experts predict that from 2020 to 2025, the average life expectancy of human beings will exceed 70 years old, and by 2300, the life expectancy of human beings can reach 95 years old, more distant future, Human life expectancy can even reach 200 to 500 years, of course, at that time, we will not see, but all this premise is that human civilization will not be destroyed by us.
Seventh, crocodile, crocodile lifespan can generally reach 80 to 85 years old, and what's more, can reach more than 100 years old, the world's oldest recognized crocodile is called Freich, died in 2010, at the age of 140. Some people say that crocodiles are very fierce, a bite can kill people, in fact, this statement is wrong, crocodile personality is relatively docile, timid, will not take the initiative to attack humans, but if someone takes the initiative to harass it is a bit of a mischievous.
Sixth, the turtle, different species of turtle lifespan is also different, the longest life of the turtle is a Galapagos tortoise named Harriet, this turtle was brought back to China by Darwin during the field expedition, their new city metabolism is relatively weak, but the heart is relatively strong, studies have shown that the natural lifespan of the turtle is about 150 to 300 years old.
The fifth, the bowhead whale, is currently the longest-lived mammal on Earth, with a body size of up to 21 meters, and an average lifespan of about 200 years under normal conditions.
The fourth place, the Greenland sleeping shark, its body length and ferocity can be comparable to the great white shark, but the growth rate is extremely slow, only growing about one centimeter per year, the average life expectancy can reach 400 years, is the longest lifespan of vertebrates. But they didn't start breeding until after they were 150 years old.
The third place, sponge, it is the most primitive multicellular organism, as early as 600 million years ago has survived on the earth, to date, sponge has nearly 10,000 varieties, some of which are relatively long-lived, can reach thousands of years, and the longest-lived sponge found so far is 11,000 years old.
The second place, the latest research report pointed out that the longest-lived life on the earth is bacteria, yes, like the shortest life body mentioned at the beginning, there is a bacterium in the Antarctic that emits the smell of rotten eggs, and its life span is 350 million years old, which is a life length that Bao Ge dare not imagine.
First place, what is longer than bacteria? Yes, eternal life, what life would be eternal life? There are rumors on the Internet that it is jellyfish. The lighthouse jellyfish is a small jellyfish that has the characteristic of being able to return to old age and reverse their own body cells to rejuvenation, but this situation is only the case when they feel threatened to live, and under normal circumstances, they will still die.
So from the perspective of the level of time, there is no life that can be immortalized, and when we are entangled in the length of life, have we ever thought of what is the meaning of life, since there is no eternal life, then exploring the meaning of life is the essence of life existence.
Keep an eye on Bao Ge and take you to open more animal treasure chests!
