Turtle is gluttonous and hungry, and it won't die if it doesn't eat for a long time after eating once. Of course, it relies on its own accumulated nutrition to maintain its life activities, and it must be provided with sufficient food to accelerate its growth during artificial reproduction. Trionyx sinensis eats earthworms, animal offal, etc. Also eat vegetables, grass, fruits, etc. When food is insufficient, the same species can eat each other's leftovers or eat animal carcasses.
The living habits of turtles can be summarized as "three joys and three fears", that is, they like quietness but fear shock, yang and wind, and clean and fear pollution. Turtle is very sensitive to the sound of its surroundings. As long as there is a slight movement around, the turtle can quickly dive into the bottom mud.
In the natural environment, soft-shelled turtles like to inhabit rivers, lakes, reservoirs, ponds and other clean waters. In calm days, they often lie on the sunny shore and bask in the sun (commonly known as basking in the back), using ultraviolet rays in the sun to kill pathogenic bacteria on the body surface, promoting the healing of injured body surface, raising body temperature and promoting food digestion through basking in the back. Born smart. If there is a slight alarm, it will quickly dive into the bottom of the water without moving. It also has the ability to judge the escape path.
Extended data:
This turtle looks like a turtle. The turtle is oval in shape and flatter than the turtle. From the appearance and color, the turtle's back and limbs are usually dark green, some are light brown, and the abdomen is white and red. Its head is like a turtle, and its dorsal abdominal armor is covered with a soft outer membrane, which is softer than a turtle without the stripes like a turtle. It is surrounded by a soft and delicate skirt. Each limb has five claws. The head, neck and limbs can be stretched.
Different from other turtle shells, the bone shell has no peripheral bone plate, the surface texture is high, there is no angular external bone plate, and the abdomen (abdominal nail) is loosely connected. The trunk is slightly oval, the snout is long, the nostrils are open at the snout, and there are bone nails on the back. The limbs are short and slightly flat, with five toes and webbed membranes between them. The tail of women's body generally does not reach the outer edge of the skirt, and most men extend out of the skirt.
Turtles are warm-blooded animals, amphibians, and breathe with their lungs. I like living in rivers, lakes and ponds. Often float to the surface, stretch out the tip of the kiss to breathe, and often bask in the back on land. Turtle is very sensitive to the change of external temperature, and its life style is closely related to the change of external temperature. 10 ~ 12℃, the soft-shelled turtle enters the hibernation period, and the hibernation period of soft-shelled turtle in Hangjiahu area is from the middle of 1 1 year 10 to the middle of April the following year.
When the water temperature rises to about 15℃ in spring, people gradually wake up from hibernation and start eating. When the temperature is above 20℃, male and female turtles mate to lay eggs. Turtle has the habit of protecting eggs. After laying eggs, it will guard in the water not far from the spawning ground to prevent natural enemies from hurting it. 25 ~ 30℃ is the optimum temperature range for feeding and growth of soft-shelled turtle, and it is also the best season for artificial breeding. When the temperature exceeds 33℃, find a hole to "escape the heat". In artificial breeding, large and small turtles are not suitable for mixed breeding because of their aggressiveness.
