The 8 cm Brazilian tortoise is still immature. It has been three years since my Brazilian tortoise was raised from 8cm. Its belly shell is 22cm, and it is still growing. You think it's drums and flat necks? If it is, it is that the tortoise is breathing. In addition, Brazilian tortoises and tortoises are not the same species, but both belong to the class Hydroptera. If the turtle is 8cm long, it will grow to more than 15cm if it is a female grass (female turtle).
