There are no plants and animals that do not sleep 10

There should be none.

It is a fact that plants need to sleep. In the wild, as long as you pay close attention, you can see a kind of red clover (also called safflower alfalfa) with small purple flowers and three leaflets, when there is sunlight during the day, the three leaflets stretch to their heart's content, and when the night covers the earth, the leaflets will close together and hang their heads, which is the state of its sleep. In the park, you will often see many tall acacia trees, their feather-shaped leaves, which look lush in the sun, but in the evening, they fold together in pairs and fall asleep.

There are also many plants such as carob, mimosa, and peanut leaves that also have this phenomenon.

Not only do the leaves of the plants sleep, but so do the beautiful flowers. Like a water lily, whenever the sun rises, its beautiful petals slowly open, as if it has woken up from a deep sleep; And when the sun sets in the west, it closes its petals and falls asleep. That's why people call it "water lilies".

The tuberose flowers not only bloom at night, but are also exceptionally fragrant. There is a vegetable that sleeps during the day and blooms at night, so people call it "night pill flower".

What's even more interesting is that the posture of the flowers sleeping is varied. The carrot flower, with its head down, like a little old man dozing; The dandelion flower, when sleeping, stands up and closes all the petals, and looks like a yellow-colored feather broom.

Dolphins don't sleep, the two hemispheres of the brain work in turns, and plants don't have a good definition of sleeping ......

Dolphins seem to swim around in a never-ending way. Dolphins are mammals that originally inhabited land and later returned to live in the water, using their lungs to breathe. If they continue to sleep in the water, the dolphins will die because they cannot breathe.

Don't they really have to sleep? If so, do they sleep on land or in the sea?

In fact, if we can observe dolphins for a while, we will find that they sometimes close one of their eyes when swimming. Investigation of their brain waves revealed that one side of their brain would be asleep. That is, although they continue to swim, their left and right brains take turns resting.

Plants don't sleep. Photosynthesis is carried out during the day and dark reaction is carried out at night. There will be chemical reactions happening all the time.

Don't sleep. The animal should be a dolphin for the typical left and right brain to work in turn. There's always a brain at work.

Then its body also needs to rest.

Dolphins never sleep, and here's how:

1. It has the typical morphological traits of toothed cetaceans: spindle-shaped body;

2. A single crescent-shaped breathing hole, with intussusception of the skull, and the maxilla expands posteriorly and overlaps with the frontal bone; left-sided asymmetry of the cranial parietal;

3. The most obvious variation among the conical or nail-shaped paradental hailstones is related to the beak, upper and lower jaws, teeth and other feeding organs, the length and size of the beak, the number and size of the teeth, and the range of ecological niches occupied by different species;

4. Dolphins are aquatic mammals closely related to whales and porpoises, which evolved in the Miocene about 10 million years ago, and lived widely in shallow seas near the continental shelf, and were occasionally seen in freshwater;

5. Mainly fish.

1. Lions: In the open field, whenever the sun sets and the moon has not yet risen, lions begin their preparation activities. In many cases, they choose to hide close to water sources.

In fact, lions weigh 100-200 kilograms, and although they can chase their prey at speeds of up to 18 meters, lions can only run at such high speeds for more than a dozen seconds.

2. Wolves: Wolves are accustomed to coming out at night, and after each evening, hungry wolves often come out in groups to forage for food. As he walked, he let out a low howl.

Animal calls are interconnected communication signals. It makes different calls in different situations, and the calls have a lot to do with reproductive habits.

Wolves howl at night in order to howl each other and swarm, such as the female wolf often makes a cry to call the young wolf, and the male wolf calls the female wolf, and goes out to hunt after gathering into a pack. During the breeding season, wolves also tend to howl in search of mates.

3. Owl: The owl has a large round head, two bright eyes, soft and easy feathers all over the body, and almost no sound when flying. The owl's hearing is extremely sensitive, and even a very slight sound can instantly make the owl look around and immediately confirm the direction of its prey in the dark.

Owls also have strong claws on their feet, which are sharp tools for predation.
