There are many ways for tortoises to distinguish between male and female. The safest way is to turn it over to see the belly armor. The belly armor of adult male turtles is sunken, because they need to lie prone on the female turtle when mating. Because the turtle back is smooth, the sunken place can be stuck on it, thus preventing it from breaking away. Besides, you can also look at the tortoise's tail. Usually, the male tortoise's tail is long and thin, while the female tortoise's tail is thick and short.

1. Reproductive cycle: Usually turtles mature when they are 5 years old, and they can mate and reproduce when they are 7 years old, but they also need to look at their weight. Generally, the male is about 150 grams and the female is 250 grams. In the natural environment, they will lay eggs from the end of April to August, with May-July as the peak period. They can lay eggs 3-4 times a year, every time every 10-25 days, and each time they can lay 5-8 eggs.

2. Oviposition process: Turtles will choose a good acupoint before laying eggs, usually beside the roots of trees with loose soil and can prevent enemies, and then they will start digging holes, with the hole mouth about 3-4 cm and the depth of 8-9 cm. After digging, the mother turtle will lay her eggs in the hole and then cover them with soil. The whole process takes about 8 hours.

3. Young turtles shell: Turtle eggs generally turn purple after 30 days of production, turn black after 70 days, and have a hard texture, and break their shells after 80-90 days. Generally, they can enter the water and live independently after they come out of their shells.
