How are bats formed?

Bats are an independent species and will not be changed by other creatures.

Bats are Chiroptera. Chiroptera is the second largest animal after rodents, and it is the only mammal that has really evolved the ability to fly. There are 19 families, 185 genera and 96 1 species. Except for some islands in the polar regions and oceans, Chiroptera are distributed all over the world, with bats in the tropics and subtropics being the most abundant. Most bats rest during the day and eat at night.

Bats use sound waves to find food. When they fly, they emit sound waves with high frequency. When a sound hits an insect, it will reflect an echo, and bats will locate the insect according to the echo. The technique of using sound waves to find food is called echolocation. The bat sends a signal from its mouth or nose. The signal hits the insect and reflects back, telling the bat where its dinner is.

Bat and radar navigation

Scientists have found that bats do not fly with their eyes and hunt at night, but rely on the cooperation of their mouths and ears to find their way. After the bat sends out ultrasonic waves with its mouth, when the ultrasonic waves hit an obstacle and reflect back, it receives signals with its ears to determine its position.

According to the method of bats flying at night to hunt, scientists installed radar on the plane. The radar sends out radio waves through the antenna, and when it meets obstacles, it reflects back and displays them on the screen. Pilots can judge the flight safety of aircraft at night from the information on the screen.
