Animals that do not sleep: intelligence and dangers Before presenting you with a detailed list of animal species that do not sleep, we want to make you think a little about this question. Well, when we talk about animals that do not sleep, we refer to species that must rest in short periods of time and superficially. Their own physiognomy or conditions of danger and stress. The brain is a complex organ, responsible for giving orders to the body.

Animals that do not sleep: outstanding species If you are a lover of animal curiosities, you would surely like to work in a Zoo. This species usually lives wild in the African savannah. This is why giraffes hardly sleep. At most about two hours a day in periods of ten minutes spread throughout the day.
These animals live in fear of being eaten, so they worry about their appearance. And even if they sleep ten minutes, it is a light sleep, to be able to escape at the slightest hint of danger. Horses and donkeys, light sleeper standing up and deep sleeper lying down Horses Equus caballus could say that they have less endurance than giraffes. This animal, classified as a non-sleeping species, actually requires at least three hours of sleep a day to recharge its batteries.
The same goes for donkeys Equus asinus. These species have been domesticated throughout history, but there are still specimens that live in the wild. This is where we find differences regarding the rest of horses and donkeys.
Fear is once again a determining factor, which is why, in order to be always alert, wild horses and donkeys sleep standing up and without reaching deep sleep phases. To give you an idea, horses only reach REM sleep if they sleep lying down and in spaces where they feel safe. The white shark Carcharodon carcharias, considered the owner of the seas, does not have the problem of feeling in danger, but it does have a worse one.
This marine species breathes through the gills, but it has the peculiarity of not having opercula, bony structures whose function is to protect the gills. This is the reason why sharks are considered animals that do not sleep, since to do so they need to be in motion, and thus stay afloat.
This is where the shark and other species with this same problem get carried away by sea currents where they do not need to move consciously. It is at this time that he takes the opportunity to sleep, albeit very briefly and in a very light sleep state. That is, it breathes through its lungs, which is why it needs to go to the surface to catch air.
This feature prevents you from spending long periods of time in the water without coming out to breathe, so your rest is limited. This is called unihemispheric slow-wave sleep, a type of behavior that causes the dolphin to sleep with one of its eyes open. They also rest only half of the brain; On the other hand, like sharks, this marine species needs to be in constant movement to avoid sinking, so to sleep, it must look for a sea current.
However, it is also common for whales to take advantage of the moment they come to the surface to rest. But in these cases they can only do it for half an hour, because they are marine animals and need to submerge again.

However, there is a group of animals that work the opposite: they sleep during the day and are active at night. We cannot classify them as animals that do not sleep, because the truth is that they do, but let’s say that they go the other way around. Some examples are: The botfly Craseonycteris thonglongyai. Because this species is highly sensitive to light, so they take advantage of moments of light to keep their eyes closed and, incidentally, sleep.
The Aye-aye Daubentonia madagascariensis, a species endemic to Madagascar that is only active at night. Take advantage of the hours without light to hunt insects with its long fingers.
