The life span of yellow-headed turtles is between 70 and 90 years, and their life span is relatively long among turtles. But how long they can live is influenced by their environment and physique. Wild yellow-headed turtles, as long as the living environment is not polluted, can live more than 70 years, and some can even live to 90 years. However, the life span of artificially bred yellow-headed turtles will be relatively shorter. Because there is not enough space for artificially bred yellow-headed turtles, and the breeding environment cannot be completely restored to the wild. In addition, when they are raised in captivity, they are prone to illness at an early age, so their life span will also be affected. Of course, farmed yellow-headed turtles have a longer life span, but they are not very common.

The length of the yellow-headed turtle is about 50-80 cm. How big they can grow depends on whether there is enough living space. Because their adaptability to the environment is relatively strong, the environment does not have a great influence on their body shape. Because they grow fast, the space for raising them is particularly important. If there is enough space, their body size will develop larger. If there is not enough space, their body size will not develop very much. If breeders want to make them grow bigger, they'd better prepare a larger container for them, and ensure that they have enough food and nutrition.
