Temperature difference between morning and evening 10 degrees.

The temperature difference between turtles should not be too large, and 5 degrees is acceptable. 10 estimates that there is a possibility of pneumonia.

Temperature difference refers to the difference between high and low temperatures. People like warm-blooded animals can adjust their body temperature and keep it relatively stable when the ambient temperature changes. Turtle is a temperature-changing animal, its body temperature will change with the change of environmental temperature, and its metabolism depends on absorbing heat from the environment. When the environmental temperature difference is too large, the turtle will have a stress reaction, which is beyond its own tolerance, leading to the decline of the body's immunity, and then lead to various diseases. Mild cold, runny nose, indigestion, severe pneumonia, gastroenteritis, and even sudden death.

Temperature difference has such a great influence on turtles, so what factors are likely to lead to excessive temperature difference and how to prevent it?

1, temperature change. When the seasons alternate or the weather is extreme, it is easy to produce a large temperature difference, which is also the high incidence period of turtle disease. Keeping turtles should pay close attention to the weather and take timely heat preservation measures.

2. change the water. We have always stressed that fresh water should be dried for two days before it is used to change water. In addition to removing harmful substances from water, it also plays a very important role, which is to keep the old and new water temperatures as consistent as possible.

3. Air conditioning and heating. When raising turtles indoors, we should pay special attention to one problem, that is, when turning on air conditioning or heating, we should keep the turtles away from air conditioning and heating, and avoid direct blowing of air conditioning and heating baking.

Step 4 bask in the sun. Sunlight plays an important role for turtles, but when basking in the sun for turtles, we should also pay special attention to the temperature problem to avoid exposure to the sun for a long time, resulting in heatstroke for turtles.

Step 5 heat up.

The purpose of our heating is to provide a suitable environmental temperature for the soft-shelled turtle, but improper heating measures will cause the local temperature to be too high and the overall temperature difference to be too large, which will easily lead to the soft-shelled turtle getting sick.

The tortoise is a semi-aquatic and semi-terrestrial reptile. Mainly inhabit rivers, lakes, reservoirs, ponds and other waters. Many people are trapped in the water during the day and look for shade in droves when it is hot in summer. Gentle temperament, do not fight with each other. When the enemy is injured or frightened, the head, limbs and tail are retracted into the shell.

Turtles are omnivorous animals, feeding on animals, insects, worms, small fish, shrimps, snails, mussels, tender leaves of plants, duckweed, melon skin, wheat grains, rice and weed seeds. Strong hunger tolerance, not eating for several months will not starve to death.

Turtles are warm animals. When the water temperature drops below 10℃, it will hibernate in mud or covered loose soil at the bottom of the water. The hibernation period generally lasts from 1 1 to the beginning of April of the following year. When the water temperature rises to 15℃, it moves out of the cave and begins to eat when the water temperature is 18℃ ~ 20℃.

How long the tortoise will live is still inconclusive. Generally speaking, it can live 100 years. According to relevant research, it has been more than 300 years, and some even have thousands of years. Turtles grow relatively slowly. Under normal circumstances, the growth speed of female turtles is: the weight of one-year-old turtles is about 15g, that of two-year-old turtles is 50g, that of three-year-old turtles is about 100g, that of four-year-old turtles is 200g, that of five-year-old turtles is about 400g. Male turtles grow slowly, and the maximum sexual maturity is generally less than 250 grams. The recipes include worms, snails, shrimps and small fish. Turtles eat a wide range of foods, including rice, wheat, peas, small fish, shrimp, insects, snails, etc. Among them, the favorite foods are small fish, snails, corn and rice.

Turtles are distributed in most coastal turtle (Terrapene carolina major) areas in the world, and existed in the same form at least 200 million years ago. Existing 200? 250 species, mostly aquatic or semi-aquatic, mainly distributed in tropical or sub-tropical regions, many of which are distributed in temperate regions. Some turtles live on land, some live in the ocean, and the rest live in fresh water. Eat fresh plants or small animals, or both. Can endure long-term fasting. Usually once a year, females lay eggs on land, and the eggs are white, round or slender. Usually, females dig holes with their hind legs and lay eggs in the holes.

Except Northeast China, Northwest China and Xizang Autonomous Region, it is distributed all over the country, but the output in the middle and lower reaches of the Yangtze River is relatively high.

Foreign countries are distributed in Japan and South Korea; Turtles are widely distributed and adaptable. However, due to serious environmental pollution, habitat destruction and man-made over-predation, it is very rare and endangered in China, and can be artificially propagated in large quantities.
