What is the diameter of turtle shell?

The tortoise shell is slightly flat, and the dorsal abdominal shell is fixed. The back shell is 65,438+00-65,438+02 cm long and 65,438+05 cm wide with three vertical ridges. There are yellow linear stripes on the side of the head and neck, slightly flat limbs, webbed fingers and toes, and claws at the end of toes except the fifth hind limb.

Turtles generally live in rivers, lakes, swamps, reservoirs and mountain streams, and sometimes they go ashore. In the natural environment, turtles feed on worms, snails, shrimps and small fish, and also eat the stems and leaves of plants. The tortoise is a kind of temperature-changing animal. When the temperature is above 150C, it moves normally and eats a lot, while when the temperature is below 10 C, it goes into hibernation. Tortoise activity is frequent from April to June every year, 65438+ 10. During this period, every day at sunset, turtles began to swim around in the water for food, and did not stop foraging until dawn, and often climbed ashore from 10 in the morning to 16 in the afternoon on sunny days, which was better than sunbathing on the shore. The feeding peak of turtles is from June to August, and the food intake decreases gradually in June 6- 10/October, and they hibernate in June-March.

In addition, turtles also have the following characteristics: low reproduction rate and slow growth. A turtle weighing about 500g will gain weight after feeding for one year100g. But the tortoise has a strong hunger tolerance, and it is not easy to starve to death even if it is deprived of food for several months. Strong disease resistance and high survival rate. So turtles are relatively easy to raise artificially.
