The life span of musk turtles is generally about 15-25 years, which is relatively short compared with other turtles. And how long they can live depends on the environment in which they live and the way they are raised. If they are wild musk turtles, as long as they live in a suitable environment, their life span will be longer than that of farmed turtles. But if the living environment is polluted, their life span will not be too long.

The life span of captive musk turtles is mostly between 15 and 20 years, and even if the breeding method is proper, most of them can only live for 20 years. If they are not paid attention to when they are raised at ordinary times, which leads to their frequent illness, their life span will be greatly reduced.

How old musk turtles are can be judged by their age and body shape. Normally, musk turtles are considered adults when their body length reaches 10-14 cm. However, female turtles and male turtles are different in adult size. Female turtles are 12-14 cm long, while male turtles are 10-12 cm long, even if they are mature.

In addition to judging by body shape, breeders can also judge by age. For musk turtles raised in the same environment, it takes 5-9 years for female turtles to mature, and only 4-8 years for male turtles to mature. If breeders want to judge whether they are mature or not, they can combine their age with their body size, which can make a more accurate judgment.
