This bat's vision that is very active at night is very bad if you have to look from a distance. In order to be able to move and fly quickly in the darkness of this bat using Echoloration. This echoloration is a transmission for sound waves to look for objects, or food and to detect obstacles. This very high-frequency sound coming from the mouth of the bat itself is beyond the reach of human hearing. Some of these bat species also produce this sound from the nose when the bat is eating while flying.
The way it works from this echoloration is the sound waves that come out away from the bat and then bounce off the object around it and form an echo and bounce back towards this bat. This bounce is bounced which provides information about the size, shape, direction and distance of the object against this bat at night.
