How long is the life span of turtles? What kinds do you have?

Tortoises, also known as golden turtles, mountain turtles, grass turtles, etc., are turtles that live longer than humans. They are widely raised because of their high ornamental value. At the same time, many kinds of turtles also have high medicinal value, so they are very popular. How long is the life span of the tortoise? What kinds do you have?

1. The secret of tortoise longevity:

Cell studies have found that the reproductive algebra of animal fibroblasts is proportional to animal lifespan. However, the cell differentiation of tortoise is slow, and there are many times of reproduction, and its fibroblasts can reach 125 generations in vitro, while human fibroblasts can only reach 50 generations. In addition, the tortoise has a slow metabolism and can slow down its physiological rhythm and enter a state of suspended animation. So they live longer.

Second, how long is the general life span?

Relevant data show that: "its natural life is generally 150 years." according to relevant textual research, there are more than 300 years, and some even over a thousand years. "

The world's longest-lived tortoise, the Galapagos tortoise, usually lives 200, 000, 300 years.

The shortest-lived tortoise in the world: a small number of American water turtles, including four golden ghosts and diamond-spotted turtles, the shortest live for 10 to 15 years.

Third, how to calculate the age?

1. Calculated according to the pattern of tortoise back.

The tortoise's annual ring is relatively clear before the 10-year-old. Shortly after the baby turtle was born, some radial lines were seen on the hard skin of the shield in the middle of its back shell, but there were no round wheels. The tortoise's back carapace pattern with several wheels, that is, the age of the tortoise, the older it is, the more difficult it is to recognize with the naked eye.

With the periodic change of nature, the tortoise has obvious growth period and hibernating period. during the growth period, the scutellum grows like the body, forming a loose and wide concentric ring, and during the hibernation period the tortoise enters a dormant state and stops growing. the back armour shield almost stops growing, and the concentric ring formed is narrow and tight. Such a dense concentric ring is similar to calculating the tree's age based on the tree's rings, and a ring appears when it goes through a winter when it stops growing. According to this, we can judge the age of the tortoise, that is, the number of concentric rings on the shield, and then add 1 broken shell to be born into a ring, which is equal to the actual age of the tortoise.

2. Calculate according to the weight of the tortoise

The growth of turtles is relatively slow. under normal conditions, the growth rate of female turtles is as follows: the body weight of the first-year-old turtle is about 15g, the second-year-old turtle is 50g, the third-year-old turtle is 100g, the fourth-year-old turtle is 200g, the fifth-year-old turtle is 250g, and the sixth-year-old turtle is about 400g. The male tortoise grows slowly, and the largest sexually mature individual is generally less than 250g.

Of course, different turtle species, ring clarity and the existence of rings when hatching and other factors will also affect the accuracy of age, so we can only make a calculation, can not be used as accurate data.

The life span of pig-nosed turtles is about 25-30 years, and the wild pig-nosed turtles can reach 50cm, which shows that they are large turtles. Domestic pig-nosed turtles are characterized by limited tank size, extremely aggressive, strict water quality requirements, slow seedling growth and so on. In fact, the history of raising pig-nosed turtles is also very short, after all, it belongs to a species that has just been overcome by humans and bred artificially.

17. Grass turtle

Grass turtles live for about 20 to 30 years, and flower turtles also fall into this category. It has been recorded that the longest artificial life span is 50 years. It is also a turtle species with a high popularization rate, and long-lived turtles can be found everywhere.

22. Mata Mata turtle
