🤔 How it works …….. ⁉
Why did bats evolve to hang upside down?
They hang upside down is because a bat’s talons or back claws work opposite of most muscles. In fact, their knees face backwards. When they relax, special tendons lock the toes and talons in place, so they do not exert energy while hanging.
Once their toes and legs are locked in place, their body weight and gravity keep them hanging. By flexing leg muscles, the toes and talons release and flight begins.
Humans cannot hang upside down as blood rushes to the head and tends to pool or collect. But the bat’s compact, small size allows their heart to easily distribute the small volume of blood even when upside down.
Because of their unique physical abilities, bats can safely roost in places where predators cannot get them. To sleep, bats hang themselves upside down in a cave or hollow tree, with their wings draped around their bodies like cloaks. They hang upside down to hibernate and even upon death.
😳Why❓❓❓
*If bats are blind, why do they have eyes?* 🦇
Bats are not blind and can in fact see quite well using their eyes. While most bats do have advanced ears that give them a form of vision in the dark known as echolocation, these good ears does not require them to have bad eyes. Bats use their good hearing to find food in the dark of night, and their good eyes to find food during the light of day. The vision of bats is tuned to low-light conditions such as is present during dawn and dusk.
As expected in a nocturnal mammal, their eyes are heavily loaded with photoreceptor cells called rods, which maximise their ability to see in the dark.
At night, however, most bats use echolocation to find prey – sending out ultrasonic sound waves and listening for the echoes. So bats can ‘see’ with both their eyes and their ears.

Did you know ?
What is the reason for foul smell from mouth?
The most common cause of halitosis is bad oral hygiene. If particles of food are left in the mouth, their breakdown by bacteria produces sulfur compounds. Keeping the mouth hydrated can reduce mouth odor. The best treatment for bad breath is regular brushing, flossing, and hydration.
Bad breath can be a warning sign that other diseases or illnesses are present. Postnasal drip, respiratory and tonsil infections, sinus problems, diabetes, liver and kidney issues, as well as certain blood disorders can all cause bad breath.
Ways to stop bad breath:
Brush teeth twice a day. Brush your teeth two to three minutes at least twice a day to remove plaque and food debris.
Floss daily.
Brush or scrape your tongue.
Use a mouth rinse.
