Habit 1. Turtles are omnivores. When they are in the wild, they are generally small fish, occasionally eating aquatic plants, chinemys reevesii, snapping turtles and sometimes ducks. Elephant turtles living in the Galapagos Islands feed on cacti. Second, the tortoise's shell is curved for a reason. According to experiments, an arc with the same volume can bear twice the weight of other objects. It is for this reason that the tortoise's shell has not changed since the dinosaur era. The sex of the three young turtles depends on the temperature. If the temperature at hatching is above 36.5 degrees, it is generally female; Below 36.5 degrees is generally male. Therefore, if the upper part of a nest of eggs is exposed to more sunlight, it will be female; There's little sun down there, so it's a man. 4. The tortoise hibernates in Taiwan Province Province, but because the weather in Taiwan Province Province is warmer, it doesn't sleep all the time, just eats less and moves less. The reason why the tortoise likes to bask in the sun is that the tortoise is a cold-blooded animal and needs sunshine to maintain a certain temperature to help digestion. But also can increase vitamin E and destroy some microorganisms in crustaceans. Sixth, the distinction between men and women. The first is to look at the abdominal armor, which is concave for men; Mother's breastplate is flat. The first is to look at the anus, and the male anus is outside the carapace; Mother's anus is in the carapace. Four. Feeding method 1 The ideal method is to keep it in an aquarium with automatic temperature control (32 degrees) and a filter that doesn't rest day and night. Put a fluorescent lamp on the top of the aquarium and decorate a few fish to swim around in it, so that the water that can be touched by the turtle's feet will be fine. Put more when feeding, so as not to hide in the water and refuse to eat. When feeding feed, the water should be as high as his head, which is more convenient for him to eat. It is best to cover the turtle shell with water level. On the principle of exposing the head for about 3 minutes, after feeding, the water should also be poured out. In summer, of course, give him a high water level, and there is also a beach to sunbathe. He often changes it in summer because he often poops. If you feed it every day, you have to change it every three days and change the water every two to three days. Also, when the weather is cold, it is best to put the water for two or three days before using it. If there is really no space and time, use tap water. Usually the staple food is mainly feed, and occasionally vegetables can be fed. It's best not to feed them fish, otherwise the color of turtle shells will not be so green. I haven't eaten anything after feeding for 20 minutes, so I need to clean it up. When the weather gets warmer, you should stare at him every day, because some turtles forget to eat and then die. Note: (The tortoise is fierce, so be careful not to be bitten when touching it. If bitten, just put his head in the water and he will let go when he wants to breathe. Whenever the climate gets cold and food is scarce, many animals go into hibernation. So hibernation is a way for animals to adapt to bad environment in struggle for existence. When animals hibernate, they will not starve to death if they don't eat for a winter. Because before hibernation, they have already started preparations for hibernation, that is, since summer, they have gradually accumulated nutrients, especially fat, in their own bodies. When hibernation comes, the body accumulates quite a lot of nutrients, so it looks obese. These accumulated nutrients are enough to meet the needs of the body during the whole hibernation process. Although a lot of nutrients are accumulated in the body, the hibernation period lasts for several months. How can it be enough? It turns out that when animals hibernate, they can't eat or move, or rarely move, so the number of breaths is reduced, the body temperature is also lowered, the blood circulation is slowed down, the metabolism is weak, and the nutrients consumed are relatively reduced, so the nutrients stored in the body are sufficient. When the nutrients stored in the body are almost used up, the hibernation period is over. Animals after hibernation are very thin. After waking up, they should swallow a lot of food to supplement nutrition and return to normal body as soon as possible. (It is an adaptation to the cold climate in winter, because it is a warming animal. ) Before and after beginning of winter, the turtles in the pond went into hibernation. If the wintering place is not good, the soft-shelled turtle will not be able to overwinter normally, which will directly affect the growth and reproduction in the next year. Turtles spend the winter in limestone caves with high humidity, most of which are sheltered from wind and light in the east-west direction, and some caves are in the north-south direction. Before overwintering, some caves should be set up in the sunny place on the shore of turtle pond for turtles to enter the caves freely to hibernate. The wintering cave is very suitable. When the temperature drops below 13℃, it begins to hibernate in clusters. During the whole wintering period, the head, tail and limbs all shrink into the shell, close your eyes, and do not eat, move or excrete until they emerge from the sting. If the environment does not adapt, it is difficult to enter a dormant state. The hibernation temperature of turtles is 1- 10℃. Above 10℃, it is easy to wake the turtle, which will consume physical strength and lead to the decline of the turtle's physique, which is not conducive to the growth and reproduction in the coming year. Repeated hibernation and awakening during hibernation can also lead to the death of turtles. Temperatures below 0℃ will frostbite turtles and even freeze to death. Therefore, the possible temperature change factors must be considered when setting up hibernation places for turtles artificially. Gui Ling building
