Will the turtle painted on Taobao fade? Is it harmful to turtles?

This kind of turtle is artificially painted to attract people's attention and gain commercial benefits. As time goes on, this color will slowly fall off and return to its original color. It must have hurt the tortoise, but the degree of damage is different.

The concave belly of a turtle is male and the convex belly is female. The tortoise's shell is flat to reduce the resistance of swimming in the water; The tortoise's carapace is relatively convex, and it is more able to withstand trampling.

With the periodic changes of nature, turtles have obvious growth period and hibernation period. In the growing period, the carapace grows like a body, forming a loose and wide concentric ring. During hibernation, the tortoise enters a dormant state and stops growing, and the carapace almost stops growing, forming a narrow and tight concentric ring.

Such dense concentric rings are similar to calculating the age of trees through their rings. When winter stops developing, annual rings will appear.
