The life span of turtles is related to their species. For example, elephant turtles and sea turtles can live for more than 100 years, smaller turtles can only live for 60-70 years, and domestic turtles live for about 30 years. Usually, its life span is positively correlated with its size. The bigger the turtle, the longer it lives, and the smaller the turtle, the shorter its life span. If you want the turtle to live for a long time, you must pay attention to the feeding method, change the water regularly and bask in the sun every day.

1. Shell protection: Animals living in the wild environment will inevitably encounter various natural enemies, while turtles have a hard shell to prevent them from being harmed. At the same time, it can also protect internal organs and reduce water loss.

2. Slow metabolism: It is known that turtles move slowly, are sleepy, and have the habits of hibernation and summer sleep, which make their metabolism extremely slow, so that their energy consumption will be reduced, thus making them live longer.

3. Strong cell reproduction ability: The cell reproduction algebra of different organisms is different. Taking human beings as an example, if embryonic lung fiber cells are cultured in vitro, they can continue to 50 generations, while turtle cells can reproduce to about 110 generations, which can also increase their life span.

4. A wide range of feeding habits: Turtles are omnivorous animals, which can be eaten by both animals and plants, so they can prey in many environments. Moreover, it is very hungry, and what it eats is not completely digested, but stored in the body, so that it can not eat for a long time.
