Little Brown Bat
These small flying mammals emit ultrasonic pulses through their larynx that humans can’t hear. Their enormous ears catch even the faintest returning echoes. Little brown bats hunt mosquitoes and moths across North America. They increase their pulse rate dramatically when closing in on prey. While pursuing insects, they can emit up to 200 pulses per second. This rapid-fire approach gives them pin-point accuracy when hunting in complete darkness or through dense forest canopies.
