The division number of tortoise embryonic cells can reach about 110 generations. In terms of innate factors, it has a longer life span than ordinary animals. The turtle has a hard shell that protects its head, abdomen, limbs and tail from the outside world. At the same time, turtles also have the habit of lethargy. They have to sleep for about 10 months a year, both in hibernation and aestivation. This makes their metabolism slower and consumes very little energy. In addition, the turtle's longevity is also related to its breathing method.

1. Being born with a "longevity gene"

Not only does it have a long "life clock", but the number of embryonic cell divisions can reach about 110 generations. Therefore, in terms of innate factors, it has a longer life span than ordinary animals.

2. Turtles have unique body structures and physiological functions

Turtles have a hard shell that protects their head, abdomen, limbs and tail. , to avoid damage from the outside world. At the same time, turtles also have the habit of lethargy. They have to sleep for about 10 months a year, both in hibernation and aestivation. In this way, their metabolism becomes slower and their energy consumption is very small.

3. Unique breathing method

Because turtles have no intercostal muscles, when breathing, they must move up and down with the lower part of their mouth to suck air into the mouth and force it to the Lungs;

4. The heart function of tortoises is strong

The heart function of tortoises is very strong. Zoologists and medical scientists have examined the heart function of tortoises and isolated the hearts of tortoises. After taking it out, it was able to beat on its own for 24 hours.
