How animals sleep:
1. Open your eyes. Animals can sleep with their eyes open, like fish. Therefore, when breeding fish, we cannot judge whether the fish sleeps by its eyes, but by whether it swims.
2. Sleep standing up. Animals can sleep standing up, such as horses, giraffes, elephants, penguins, red-crowned cranes and other animals. Among them, red-crowned cranes sleep standing independently on one leg. Horses and penguins are extremely alert. so that they can detect the danger.
3. Sleep while swimming. Dolphins can sleep while swimming. At this time, one eye of the dolphin is open, while the other eye is closed and asleep. Moreover, dolphins are a kind of marine mammals with constant body temperature and no hibernation habit.
4. Sleep on your stomach. Dogs, wolves, leopards and other animals lie downhent with their ears on the ground, so they can quickly sense movements around them and react accordingly. Additionally, cats, lions, tigers and other animals often lie down together. place to rest during the day.

10,000 meters under the sea is a very cold and dark place. The pressure there is very high, equivalent to a weight of 20 tonnes weighing on a person. The darkness of the surrounding environment is enough to scare someone crazy.
10,000 meters under the sea is almost as far as the Mariana Trench can reach. Because it is so deep in the seabed, sunlight cannot penetrate it. PeNo one knows if it is some kind of species. will appear from somewhere. Powerful unknown creatures. It is currently believed that no marine life can survive 10,000 meters under the sea due to excessive water pressure. However, it remains to be verified whether this is the case. The famous director Cameron once said that at the edge of survival, 8 kilometers under the sea, it is already a desolate world without any sense of life, as if arriving on another planet. ?
10,000 meters under the sea is a place where light cannot reach, so there is no light source there, just endless darkness. Faced with this gloomy atmosphere, humans generally feel very nervous and afraid. Fear of the unknown and the dark often makes people feel stifled and oppressed. The deep sea is also an extremely cold place, where all the heat will be captured by the sea water. The freezing sea water and the enormous pressure surroundnt the divers. You can imagine the psychological pressure divers are under. It is precisely because of such an extreme pressure environment that some say that in such deep seas, roars coming from the ground can be heard. Such a superstitious statement is more likely to be caused by auditory hallucinations caused by extreme mental stress, which is also completely normal.
In fact, it is difficult to find marine life at a depth of about 8 kilometers under the sea. Scientists believe that for marine life, 8 kilometers under the sea is their limit.limit . The creatures that live here are often ugly and huge, and due to the lack of resources, these deep-sea creatures often fight to survive. Many of these creatures have sharp teeth and strange skin to better adapt to the underwater environment.
