The hatchlings mainly look at the belly and tail.
Flat belly, short and thick tail: female.
Concave belly, slender tail: male.
Don’t listen to the nonsense about looking at belly patterns.
If the turtle is larger, you will know by looking at the body shape. Female turtles of the same species are generally several times larger than male turtles.
How you choose a name depends on what you think is fun.
My family has 4 Brazilian turtles.
The 8-year-old is called A Bao, and the 6-year-old is called Er Bao. They were later given to their aunt.
The other 6-year-old is called Xiaobao,
There is also a 1-year-old newly bought this year called Mopan.
It is most fun to raise turtles from a young age, and they will also become more familiar to you.
