1. Distinguish the excretory hole: To distinguish the male and female of the flame tortoise, it needs to be carried out when the body size is relatively large. There is basically no way to distinguish them at the young tortoise stage. The distinguishing characteristics are more obvious after they grow up. First, they can be distinguished from their cloacal pores. The location of the cloaca is different, the male cloaca is closer to their tails, while the female cloaca is farther from their tails. The shape of their cloaca is also different, the male's cloaca looks longer, while the female's looks round.
2. Tail difference: The tail size of male and female turtles is also different. The male turtle's tail is thick and big, but the female turtle's tail is thin and short, sometimes easier to observe.
3, the difference between the plastron: both the plastron is also different, can be observed to distinguish between male and female. There are obvious depressions on the plastron of male turtles, but not on female turtles.
The flame turtle male and female turtle's back shell may be red, this is one of the characteristics of the flame turtle, but also the reason for their name. When they are relatively young, their back shell color is yellow and green, after a period of breeding can become black and red, male and female turtles have the opportunity to become red. However, not all flame turtles will turn red, there are many reasons for not changing color, some are due to congenital lack of red genes, and some are due to improper breeding methods.
