BIOMIMICRY AND BATS
Bats can fly more easily than birds with their very long and spread fingers covered with membranes and patagium. Bats, the second largest order of mammals after rodents, make up about 20% of all classified mammals in the world, with more than 1,200 species.
Bats emit ultrasonic sounds to produce an echo. These sounds hit objects and return to bats. Returning sounds arrive at different times and at different intensities depending on the position of the object. The difference in duration and intensity is used by the animal to determine the position of the object. This event is called Echolocation.
Echolocation: Small bats and some large bats emit ultrasonic sounds to produce an echo. The loudness of these echoes depends on the subglottic pressure. The function of the bat's cricothyroid muscle, which controls the orientation of the pulse frequency, is important. This muscle is inside the larynx and is the only tensor muscle that can help make sounds. By comparing the outgoing pulses and the returning echoes, the brain and auditory nervous system can produce detailed images of the bat's environment. In this way, bats can detect their prey in the dark, locate and classify them. Bat calls are one of the loudest flying animal sounds, and their intensity ranges from 60 to 140 decibels. Little bats use their larynx to create ultrasound and emit it through their mouths and sometimes their noses.
