Why do animals sleep in different positions?

Animals have various sleeping postures, which are closely related to their living habits and living environment. Sea otters are used to sleeping on their backs on the sea surface, and walruses sleep upright in the water with their heads above the water. These are all manifestations of adapting to the environment and survival.

Animal sleep is a behavioral phenomenon that is widely present in the animal kingdom. When sleeping, animals remain motionless for a long time and respond slowly or not at all to external stimuli.

Each animal has its own unique sleeping posture, but the sleeping postures of animals of the same type are mostly similar.

Sleep is different from the deep sleep state caused by coma, anesthesia and drugs. Sleepers can be easily awakened by strong stimulation and return to a wakeful state.

How do monkeys sleep?

Monkeys live in trees at night. Most monkeys live in trees or semi-trees in different forms, and only a few species live on the ground or on rocks. Monkeys usually move in groups. Most of them can walk upright, but only a small part of the time. Most of them are active during the day, and some of them are nocturnal, such as night monkeys and finger monkeys.

Monkeys conceive once every six months, with 1 to 3 babies in each litter. Most monkeys are omnivorous, eating plants, but also meat. The way monkeys obtain food varies.

Monkeys, like humans, belong to the order Primates in zoology. They have well-developed brains and high intelligence. If trained, monkeys can help humans do many simple tasks, such as turning on and off lights, herding, picking fruits, and delivering letters. Therefore, monkeys have received attention and protection from humans.

Because monkeys and humans belong to the same subject, countries around the world often use monkeys as experimental animals. Cambodia, Vietnam, India and other countries provide a large number of monkeys to laboratories around the world every year.

How do owls sleep?

Owls sleep with one eye open and one eye closed. Owls living in the woods are used to coming out at night to catch voles for food, so they sleep during the day. When they sleep, they always open one eye and close the other, letting the two eyes rest in turn, and sleep in the tree.

Owls, like cats, only need a short nap to restore their energy. They sleep with one eye open and one eye closed to monitor their surroundings at all times and guard against enemy attacks.

Most owls are nocturnal animals. During the day, they usually hide in bushes, caves in rocks, or eaves to sleep, and only come out at night.

There is a light-reflecting membrane behind the pupil of an owl's eye, allowing light to pass through the pupil again and enhance low-light vision at night.
