Tortoise, also known as Kin ki, Turtle, Mountain Tortoise, etc., belongs to the genus Tortoise, Tortoise, but in a broad sense, it is actually a general term for all animals under Tortoise, and in a narrow sense, it is a species under Tortoise. Turtles are widely distributed, mainly in the south in China, and mainly in Japan, South Korea and other countries abroad.
2. Tortoise is an ancient reptile existing in the world. Most tortoises are carnivores, mainly feeding on worms, shrimps and small fish, as well as the stems and leaves of plants. The tortoise has a very hard shell. When it is attacked, it can retract its head and limbs into the shell.
3. The life span of different species of tortoises is different, generally speaking, it is between 20 and 50 years, and the life span of a few large tortoises can be as long as 200 to 300 years.
According to living habits, turtles can be divided into tortoises, semi-water turtles and water turtles.
Among them, tortoises have the longest life span, which can generally survive for more than 100 years. Experts have investigated large tortoises that eat plants on some islands near the Pacific Ocean, and their life span has even reached 300 years. The life span of a semi-water turtle is in the middle, generally 30-50 years, and the life span of a water turtle is relatively the shortest, generally between 20-30 years.
4. Besides the influence of species, the life span of turtles is also affected by many factors, such as living environment, body structure and physiological function, etc. To ensure that turtles have good eating conditions and can hibernate and sleep in summer regularly, they will survive for a long time. If we don't pay attention to the control of feeding, environment and diet, the life span of turtles will be greatly shortened.
Compared with most other animals, the tortoise has a very long life. Because the growth cycle of the tortoise is very slow, the physical consumption is less, and the metabolism of the body will be slower accordingly, which makes the tortoise's life span so long;
Secondly, compared with other species, the tortoise's physiological metabolism will be less, and there is a carapace as protection, and the tortoise itself can adjust the speed of metabolism, so the tortoise's life span can generally be longer.
