Crocodile turtles are divided into big crocodile turtles and small crocodile turtles, and the life span of different species of crocodile turtles is also different. Normally, the life span of crocodile turtles is relatively long. If they are wild crocodile turtles, their life span can reach about 80-100 years. However, the life span of artificial breeding will be relatively short, about 20-70 years. Because different feeding methods also have a great influence on their longevity, if properly raised, their longevity can reach more than 70 years.

The life span of small crocodile turtles is shorter than that of big crocodile turtles, and the life span of wild small crocodile turtles is about 30-50 years. The life span of artificial culture is about 20-30 years.

In order for snapping turtles to live longer, breeders need to take care to prevent diseases in their infancy, because frequent illness will affect their life span. In addition, it is necessary to ensure that they live in a comfortable environment and have enough food.

The body lengths of crocodile turtles and small crocodile turtles are different in adulthood. Generally speaking, crocodile turtles will be larger in adulthood, about 40-70 cm. If the feeding space and food are sufficient, their body length can grow to more than 70 cm. The small crocodile turtle is smaller in size as an adult, about 30-45 cm. Even if properly raised, it will not exceed 50 cm at most.
