自然界，有一种动物很懒。
洞螈常年生活在洞穴的最深处，在那里几乎没有任何光亮的存在，幽暗的环境当中十分潮湿，洞穴中有着天然的小水池，水池当中的水源都是未经污染的天然水质。
Such an environment provides the need for the growth of cave salamanders.
The salamander itself is amphibian, sometimes lurking in small pools of water and surfacing for ventilation when needed.
The cave salamander is slender, looking like a small snake, but with short limbs. 跟“娃娃鱼”有几分相似。
It looks like a lizard, but the limbs are too short, and its body length is generally about thirty centimeters, and the color of the body is white due to its long-term life in the dark.
When it was first discovered, many people thought it was the prototype of the "dragon"
In a long-term dark environment, the vision is not easy to use, the vision of the salamander is quite seriously degraded, in the process of viewing the salamander, if there is no strong light conditions, it is difficult to see the presence of its eyes.
In fact, the cave salamander has eyes, but its eyes have evolved to be particularly small due to the needs of the suitable environment, and it is difficult for people to observe.
According to scientific research, the hearing of the cave salamander is between 10 hertz and 15,000 Hz, which is comparable to the level of human hearing.
They are able to detect changes in the outside world through the vibrations generated by the water, which is also an important basis for their predation, often feeding on small fish and shrimp that fall deep in the cave.
The cave salamander eats a meal for ten years, and only mates once in 12 years, usually living motionless in the cave, it is such a lazy animal, but it can live to 100 years old.
According to scientific research, the average daily activity of the salamander is about five minutes, and after five minutes they will comfortably go back to sleep.
This is because the environment in which the cave salamander is located lacks food, and under the restrictions of the living environment, it cannot go out to hunt, and only when some small fish and shrimp and small insects mistakenly enter the depths of the cave will they have a full meal.
The lazy way of survival is actually a kind of self-protection, slowing down the speed of your body's metabolism to prolong your life, which is the most effective way.
The requirements of the cave salamander on the water source are extremely high, and the ordinary water quality cannot meet the requirements of its survival, so the cave salamander will choose the deepest part of the cave where there is the purest water source and the living environment that is not disturbed by humans.
The cave salamander is called a baby dragon because of its size resemblance to the folk real dragon totem
Nowadays, with the deep activities of human beings, the permafrost layer that has remained unchanged for thousands of years has gradually melted, and the remains of ancient creatures have been revealed.
We never know if there will be terrible ancient viruses that will reappear with animal remains.
