How many years can a turtle live?

Every 500g turtle age in the wild is about 20 years in the south and 40 years in the north of China.

The growth of turtles is slow, and the age is calculated by the number of concentric rings (growth rings) on the tortoise shell shield. One ring is a one-year growth period. Of course, different turtle species, the clarity of ring marks and whether there are ring marks during hatching will also affect the accuracy of age.

The life span of turtles is generally long, at least 20 years. According to historical records, the life span of white turtle is over 800 years old, so it has the reputation of "Millennium turtle, Millennium turtle".

Extended data:

Many turtle farms have been established in many provinces and cities in the south and northeast of China, and the breeding and breeding of turtles have been solved. However, due to the slow growth of soft-shelled turtle, there is still a long way to go to meet the demand. Japan also has specialized breeding institutions. The survey results in Zhou Ting (2007) show that the domestic stock of soft-shelled turtles is 500,000-700,000, and the stock of cultured soft-shelled turtles is more than 40,000. China has established a stable artificial domesticated population.
