New Delhi:- There are always many questions about bats in the minds of people who are interested in animals. One of these questions that bothers the most is that bats sleep by hanging upside down (why do bats sleep upside down)? Whenever you see the bats hanging under the roof or bridge of a cave .. Then you must also have the question in your mind that why does this creature sleep by hanging upside down? This is not a simple habit but the result of millions of years of development journey.

Scientists said that bats were the first -land mammals. But over time this organism developed the ability to fly. According to the Bat Biologist Tara Hohoff of the Illinois Bat Conservation Program, the bats started jumping from the trees like the first flying squirrels. For this, he developed strong legs. Which gradually turned into wings. However, like birds, their bones are not hollow. So that they cannot make much lift while flying. Because of this, bats adopt the technique of dropping themselves from height to fly.

Art of hanging
If a person tries to hang upside down from a surface, it will be very difficult for him. But the structure of the bats of bats helps them to do it easily. According to Daniel Pavuk, a biologist at Balling Green State University, when bats catch a surface, their claws muscles shrink. As soon as they leave their body loose .. Their weight puts pressure on the tendon of claws. This makes their claws closed automatically and they can remain hanging without any effort.

Relaxation without spending energy

This unique physical texture allows bats to hang comfortably without spending any extra energy. His body is completely relaxed. Gravity works for them. Unlike humans, the heart of their small body can easily circulate blood throughout the body. Due to which they can remain in this position for a long time.

Hanging provides security

This method of bats is not only helpful for flight but also proves to be effective in protecting them from hunter birds and other enemies. They are able to escape owls, eagles and snakes by hanging in inaccessible places like the roofs and bridges of the caves. Some bats can also fly from land. But it is very difficult for them. That is why they like to jump directly into the air from the hanging situation.

Some bats also sleep differently

Interestingly, not all bats sleep up by hanging upside down. The 'disk-winged bat' found in Central and South America sleeps by sticking to the surface of the leaves with the help of special elements on their thumbs. Bats are the only flying mammals in the world. Therefore, more research is needed to understand the secret of flying and hanging upside down. Scientists believe that some species of bats are more capable of flying from the ground. Therefore, it can be useful to and study on their physical texture.
