The life span of a tortoise is several hundred years. As the saying goes, "A thousand-year-old turtle is a thousand-year-old turtle". The tortoise not only has strong vitality, but also has longevity factors in its body. Generally speaking, death is closely related to cardiac arrest, but the isolated heart of a turtle can beat outside for a long time, and it can live for a few days if the glans is removed. Cell research has found that the generation of animal fibroblasts is directly proportional to the life span of animals. The in vitro culture of turtle fibroblasts is as high as 1 17 years, while that of human beings is only 50 years. Modern medical research has confirmed that the tortoise is an ancient animal of the same age as the dinosaur, but the dinosaur became extinct and the tortoise survived. Therefore, they are called "living fossils" and "turtles that never age". Eating and using turtle meat can prolong life, and the longevity factors in longevity turtles can be fully absorbed by people. The researchers also found that turtles never suffer from cancer, and their bodies contain anticancer substances. What a wonderful and meaningful event it would be if the mysteries of these creatures were applied to human beings. At present, the frontier goal of life science research is to prolong life by using turtle essence. Once this research topic breaks through, it will inevitably bring unprecedented promotion to turtle breeding. Some scientists believe that the life span of turtles is related to their size. Little turtle has a short life, but chinemys reevesii has a long life.

During the mourning, the mother turtle climbed to the beach, dug a big pit, laid eggs in the pit, and then returned to the sea. Male sea turtles never leave the ocean except for incubating their eggs on dry beaches. Some turtle experts and zoologists believe that vegetarians live longer than omnivorous or carnivorous turtles. Elephant turtles living on tropical islands in the Indian Ocean and the Pacific Ocean are the largest land turtles in the world. They feed on grass, cactus and wild fruit, so they live a long life and can live to 300 years old. Everyone thinks it's a long-lived turtle. But other turtle researchers don't think so. For example, it is not uncommon for the big-headed turtle and some omnivorous turtles that feed on fish, snakes and worms to live longer than 100 years. At present, some scientists have studied the longevity secret of turtles from cytology, physiology and anatomy. Some biologists compare a group of long-lived turtles with another group of short-lived ordinary turtles. The results showed that the reproductive generations of turtle cells with short life span were generally less. It is concluded that the reproductive algebra of turtle cells is closely related to the longevity of turtles. Some medical scientists and animal anatomists also examined the turtle's heart. After they took it out, it was still beating for two whole days. This shows that the turtle's heart function is very strong, which is directly related to the turtle's longevity. Some scientists believe that the longevity of turtles is directly related to their low metabolism, slow movement and physiological functions of drought and hunger tolerance. In a word, scientists have explored and studied the reasons for the longevity of turtles from various aspects, but the conclusions are different. Why is it different? Scientists need to conduct in-depth argumentation.
