Anomalous nature of Bats

The only flying mammal with mysterious characters. We know that bats are blind, but only the smaller species of bats use echolocation as their main means of orienting themselves. Bigger bats can see better than humans. Sight is a blessing and a curse for them because sight can override echolocation signals. For instance, a bat may fly into a window because it sees light outside, even if echolocation tells it, the surface is solid.

Why bats hang upside-down?

Unlike birds, bats have trouble with take-offs from the ground. Their wings are not as strong as those of birds and they cannot run fast enough to build up flight speed. Bats have an easier time flying when they start already in the air. They use their front claws on their wings to climb to a high spot and launch themselves to achieve flight.
Another reason they hang upside down is that 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.

The bat’s compact and small size allows its 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.

Bats help in pollination:
Over 300 species of fruit depend on bats for pollination. Bats help spread seeds for nuts, figs, and cacao-the main ingredient in chocolate. Without bats, we also would not have plants like agave or the iconic saguaro cactus. 
These characters make them unique from all the species. Nature creates the Earth for all living organisms. So live and let live.

WHY ATLANTIC AND PACIFIC OCEAN ARE NOT MIXED?

Nearly 72% of the earth is filled with water and it is present with different names- oceans, seas, rivers. Why are they named differently? There are five oceans namely Artic ocean, Atlantic Ocean, Pacific Ocean, Indian ocean and Antarctic ocean . All the oceans are different in their physical and biological character called ocean clines. When we look at the Atlantic and Pacific Ocean junction, they do not mix. Is there any invisible Wall in between them? Many scientists have conducted research to solve this mystery. The Atlantic and Pacific Ocean have different chemical composition. The salinity of the water in the Atlantic Ocean is five times more than the Pacific Ocean. The density of water is also different, so even marine animals in Atlantic Ocean will not go to the Pacific Ocean. They cannot survive in other oceans. Atlantic and Pacific Ocean meet at Cape Horn. The narrow straight line formed by the water bodies is called Drake Strait. The Pacific Ocean is ...

How did fruits get their names?

There is a variety of fruits in today's world. Each fruit has a name and the names are derived from foreign languages - modern and ancient. Some of these fruits have names that don't go with the fruit also. The name gooseberry has nothing to do with geese. It was originally called gorseberry. 'Gorse' in Saxton (a language spoken by early germanic people) means 'rough'. This fruit grows on a rough or thorny shrub. Just like the gooseberry, the fruit strawberry has no connection with straws. Strawberry is the changed name of 'strayberry'. The strawberry runners stray in all directions and hence the name. Peaches have been around for thousands of years. This fruit made its way to Europe when the Romans were around. The Romans called it 'persicum' meaning 'Persian apples. It was traded by the Persians during that time.  The national fruit of New Zealand kiwi was found in China. In other countries, it was called Chinese goo...

LEECH THERAPY

  Early Egyptian, used leeches to treat the nervous system, abnormalities, dental problems, skin disease and infections. Nowadays mostly used in plastic surgery and microsurgery. The saliva of leech secretes peptides and proteins which prevent blood clot.     These secretions also called anticoagulant to keep blood flowing will help to heal the wounds. This therapy is seeing a revival or renewal due to its simple and inexpensive means of preventing complications.     These medicinal leeches most often come from Hungary or Sweden. Leech has 3jaws in them two tiny rows of teeth. They make a hole in a person skin and insert the anticoagulant through their saliva. Each leech allows extracting (up to 15ml of blood) for 30 to 45 minutes.    Chemical derive from the saliva of leech made into pharmaceutical drugs that can treat hypertension, haemorrhoids, skin problems, arthritic appreciate treatment for common joint disease osteoarthritis, ci...
