The life span of doughnut turtles is generally about 35-40 years, and how long they can live depends on their living environment and their physique. Generally speaking, doughnut turtles living in the country of origin have the longest life span, because the environment of the country of origin is the most suitable for their growth, and there is plenty of space in the wild, and their activity area is relatively large, so their life span will be relatively long.

If it is a captive donut turtle, its life span will be shorter. Because they have high requirements for the environment, family feeding can't give them a particularly large space and can't guarantee the stability of the environment, so their life span will be shorter.

Adult doughnut turtle body length is between 20-30 cm and weight is about 2 kg. Although females and males are similar in size, doughnut turtles of different genders have different weights. Generally speaking, the weight of female turtles will be heavier than that of male turtles. Furthermore, the living space of doughnut turtles will also have a great influence on their body development. If they don't have enough living space and often get sick or uncomfortable, they won't develop too much in adulthood. If they have plenty of living space and comfortable environment, and their physique is better, they may grow to more than 30 cm.
