Why do people live as long as turtles are as questionable Thank you

In the animal world, the life span of the turtle is the longest, so the turtle is known as the "old birthday star". Although people know that turtles are long-lived animals, little is known about the reasons for their longevity. Some scientists at home and abroad have listed this as a research topic for exploration, and it has been used as an excellent animal model for studying human longevity.

According to existing research, the reasons for the longevity of turtles are still varied. Some scientists have proposed that the lifespan of a turtle is related to the size of the turtle, and the life span of a large turtle is long, and the life span of a small turtle is short. Long-lived turtles have been documented, such as the elephant tortoise, which is the largest land turtle in the world, and the sea turtle, which is both very large.

However, zoologists at the Shanghai Museum of Natural History disagree, because there is a specimen of a large-headed turtle preserved in the museum, which is far less large than that of a giant tortoise or a sea turtle, but its back armor is engraved with the words "Daoguang 20 years" (1840), which is clearly for memorization. In this year, the Opium War broke out in China. The big-headed turtle was caught in the Yangtze River in 1972 and has lived for at least 132 years from the year it was engraved until it was caught.

Some zoologists and turtle experts believe that plant-fed vegetarian turtles generally live longer than meat- and omnivorous turtles. For example, giant tortoises, which live on tropical islands in the Pacific and Indian Oceans, feed on grasses, wild fruits and cacti, and live a particularly long lifespan of 300 years. However, other turtle researchers believe that this is not the case, such as the big-headed turtle that feeds on snakes, fish, worms and other animals, and some omnivorous turtles, which also live for more than 100 years.

Recently, some scientists have also studied the secrets of turtle longevity from cytology, anatomy, physiology, etc. Some biologists selected a group of long-lived turtles and a less long-lived group of common turtles as control materials. The results showed that one group of long-lived turtles generally had more cell reproduction generations, while the other group of less long-lived turtles generally had fewer cell reproduction generations.

This shows that the number of generations of cell reproduction of turtles is closely related to the length of the life span of turtles. Some animal anatomists and medical scientists also check the heart function of turtles, and after the turtle's heart is removed from the body, it can beat for two whole days. This indicates that the turtle has a stronger heart function, which is also directly related to the turtle's longer lifespan.

On the whole, the longevity of turtles is closely related to their sluggish movement, low metabolism and physiological functions that are tolerant to hunger and drought. In short, scientists have explored and studied the reasons for the longevity of turtles from different angles, and the results obtained are also diverse. As for the exact cause, further research is needed.

The tortoise is confined to a hard carapace and moves slowly, so it consumes very little physical energy, and the tortoise accumulates enough nutrients to go without food for a long time

Because the somatic metabolism of sea turtles is slower than that of a human o(o....

TurtlesThe maximum lifespan is about 150 years.

Sea turtles (scientific name: Chelonia mydas) belong to the order Turtles, Turtles, and Turtles. It is widely distributed in the Atlantic Ocean.

Pacific and Indian Oceans.

Chinese sea turtles stretch from Shandong in the north to the Beibu Gulf in the south.

It is distributed offshore. It can be more than 1 meter long and has a lifespan of about 150 years.

Sea turtles live in the ocean for life. Feeds on fish, cephalopods, crustaceans and seaweed. From April to October is the breeding season, female and male turtles often mate on reefs or coastal waters, and the mating time is as long as 3-4 hours.

After mating, the female turtle climbs to the beach on the shore at night to dig a pit to lay eggs, first digging a large pit with the same depth as the body height on the forelimbs, lying in the pit, and then digging an "egg pit" with a diameter of 20cm and a depth of about 50cm by alternating hind limbs, laying up to 238 eggs.

Growth and reproduction of sea turtles:

April to October for the breeding season, female and male turtles often mate on the reef or coastal waters, the mating time is as long as 3-4 hours, after mating the female turtle climbs onto the shore beach at night to dig a pit to lay eggs, first dig a large pit with a depth and body height with the forelimbs, lie in the pit, and then dig an "egg pit" with a diameter of 20 cm and a depth of about 50 cm by alternating action of the hind limbs, lay eggs in the pit, and lay eggs generally from 10 o'clock at night to 3 o'clock the next morning.

After the eggs are laid, the egg pit is covered with sand and then left the beach and returned to the sea. It can lay eggs 23 times a year, with 91-157 eggs per year and up to 238 eggs. The eggs are white, spherical, leathery and soft, with a diameter of 35-58 mm.

The hatching period is 30-90 days, usually 45-60 days, and the hatchlings crawl back into the sea from the moment they emerge. Huidong, Guangdong Province, China.

The Paracel Islands in Hainan.

The coast is a breeding ground for sea turtles. The lifespan can be more than 100 years. According to the Guinness Book of World Records

It is recorded that sea turtles can live up to 152 years, and they are well-deserved old birthday stars among animals.

Turtles do not have a calcined body and do not refine qi to build ** pills, but the turtle's body can refine medicine, and the turtle's body is medicine, and the medicinal properties extend the life of the turtle, and the turtle can actually live longer. The lifespan of sea turtles is related to the biological environment of the sea. This involves a certain law of heaven and earth, and there are also laws in the ocean, the more it causes small impact, immobile, and stable creatures, the more it will fit the laws of heaven and earth, so how long can heaven and earth live, they can live as long as they can.

The key is to conform to the laws of heaven and earth on the physical level and biological level. Mortals may not understand this. In fact, it means to reduce the body's output and absorption to maintain the stability of the body, and then there is a structure to maintain the stability of the body, the flow of qi and blood, less movement in nature, and the ability to go with the flow can get a longer life.

If people live in seawater for a long time, they can live longer, because there is a more obvious "law of heaven and earth" in the ocean than on land, and the flow of seawater is its manifestation.

For people, refining Chinese medicine tonic into pills and eating them for a long time is a way to live a long life for people who don't exercise. While lean meats and vegetables, a small amount of fat is a way to live a long life for people who exercise. Movement complements yang, and stillness complements yin, this is the law that human beings can follow.

As the saying goes, "the thousand-year-old king is eighty-thousand-year-old turtle", people know that turtles and turtles are long-lived animals, and thousands of years are of course an exaggeration, but this kind of animal does live for a long time, and it is not a new thing to find turtles with a lifespan of hundreds of years in various places.

Why do turtles live so long? It's a different story.

One view is that the reason why turtles are able to live for that long is because it is a "vegetarian". They also compared people to me, saying that those centenarians and I live in remote mountainous areas and rural areas, working all year round, coarse tea and light food.

Opponents say that turtles are not all vegetarians. Some omnivorous turtles also live over 100 years, while some vegetarian turtles only live for a few decades.

Others say that the lifespan of a turtle is related to its size, such as sea turtles and turtles of a large size. However, it was immediately retorted that some very small turtles can also live for one or two hundred years, how can this be explained?

Recently, zoologists have come up with new insights, saying that the longevity of turtles may be the main reason for their longevity, due to their strong heart function and the high number of generations of thin-breasted reproduction.

People are interested in the secret of turtle longevity, because if the secret of turtle longevity is revealed, it will definitely help to study how to extend human lifespan.

Because the body structure and physiological skills of sea turtles are very special. Sea turtles are recognized as "old birthday stars". The hard, thick shell not only protects the turtle's internal organs, but also protects it from damage when attacked.

In addition, turtles have extremely strong hearts. Even if the heart is removed, it can continue to beat for two days. Therefore, the special physical properties also make the turtle live a long life.

The long lifespan of sea turtles is mainly due to the following reasons:

1. Ecological environment: Sea turtles live in the ocean, unlike land animals that are susceptible to human interference and destruction, and the living environment is relatively stable, so that they can enjoy a longer lifespan.

2. Breeding strategy: Sea turtles only lay eggs once a year, and the number of eggs laid each time is relatively large, which can reduce the pressure and risks they are subjected to during the short-lived mating period, so that they can better enjoy life.

3. Physiological mechanism: The body structure, metabolic mode and reproductive cycle of sea turtles are conducive to their longevity. For example, sea turtles have a strong immune system and DNA repair ability, a protein in the body that can delay cell aging, and longevity genes.

4. Artificial protection: Due to the improvement of human awareness of the marine ecological environment and the awareness of protection, people have begun to take measures to protect the sea turtle and its envy habitat, reduce the threats and pressures they face, and further extend the life of its pretends.

Therefore, the reason for the longevity of sea turtles is the result of a combination of physiological, ecological and anthropogenic conservation factors.
