The normal body length of the tortoise in 20 years can reach 20-30 cm, and how big it can grow depends on their environment and the sex of the tortoise. If both females and males are kept in the same environment, females will be larger than males. A 20-year-old female tortoise can grow to 30 cm, but a male tortoise can only grow to 20-25 cm. If Brazilian tortoises survive in the wild, they will be smaller than those raised at home, only about 20 cm long. Because the environment in the wild is unstable, and the food and nutrition are insufficient, they can't get too much food, which will affect the development of body shape.

The average life span of Brazilian tortoises is between 15 and 25 years. Generally speaking, the life span of domestic Brazilian tortoises will be shorter, only between 15 and 20 years. If it is raised indoors at a constant temperature, its life span will be shorter. Because they don't go into hibernation, their physique will be worse than other Brazilian tortoises. Brazilian tortoises living in the wild live longer, with an average life span of 20-25 years.

If breeders want to make Brazilian tortoises live longer, they must ensure their physical health, and usually feed more vitamin E powder to enhance their resistance. Treating diseases in time after they are found can also delay their life span.
