Turtles live a relatively long life. How to judge the turtle's age can only be roughly judged, because it is sometimes inaccurate to look at the concentric ring pattern of the turtle's carapace or abdomen, and some turtles' concentric ring patterns are not clear. Here's how to judge the age of a turtle.

According to the turtle's age, you can turn the turtle upside down and look at the spots on its abdomen. There are irregular circles on each spot, but several circles indicate the turtle's age. If the concentric rings on the turtle's back are clear, the turtle's age can be judged by counting the number of concentric rings. The number of concentric rings plus 1 is the age of the turtle.

The weight of the tortoise is related to its age, and we can roughly judge its age by its constitution. About 15g is 1 year, about 50g is 2 years old, about 100g is 3 years old, and about 200g is 4 years old. Of course, these are all based on the usual experience. We can also estimate the turtle's age according to its length. 1 year-old tortoise carapace length is less than 6 cm; Tortoise age 1 ~ 3 years old, the length of carapace is about 6 cm, less than 10 cm; Turtles with a shell length exceeding 10 cm are all adults.

We can also judge the turtle's age by the color and cleanliness of the back lines. If the lines are deep and clear, they are older. If the texture is light and unclear, it is young. The above method is to estimate the turtle's age by ourselves. If you want to determine the turtle's age and know its age clearly, you need to find a professional.
