The life span of yellow-margined box turtles raised in families is mostly between 40 and 60 years, but individual cases of very long life span cannot be ruled out. Generally speaking, its life span is relatively long. There are two main factors affecting the age of the yellow-margined box turtle, one is its own genes, the length of its life span is largely affected by genes. If the parent's genes are good, it will live longer.
On the other hand, the environment in which it is raised. If the breeder can carefully raise, in the environment, feeding and other aspects to provide suitable conditions for its growth, its life will be longer. Some turtles bought from the market are not up to the average age, on the one hand, it may be because they have a certain age, on the other hand, it may be because of improper maintenance.
In general, when the yellow-margined box turtle is six to seven years old, it enters the state of sexual maturity. After reaching sexual maturity, further reproductive behavior can be carried out. When sexually mature, it usually breeds from May to September each year, laying about two eggs at a time.
