Bats communicate with each other through echolocation, the use of very high-frequency sounds. Using sound enables bats to visualize objects of any size in their environment.Continue Reading
Bats create sounds through their mouths, but some bats produce sounds through their noses. Their sensitive ears pick up the sound reflecting off the objects around them. They rely on echolocation not only for communication, but navigation as well. Echolocation enables them to recognize the size of any object.
Bats can also determine the distance of things based on the time it takes for the reflecting sounds to reach their ears. The bats emit consecutive, loud ultrasounds that fluctuate from a high to low frequency. This helps them easily identify and capture nearby prey and avoid obstacles in the way.
Bats generate an incredible rate of 200 pulses per second at extremely high frequencies that are largely inaudible to the human ear. The hearing range of humans is around 20 hertz to 15 to 20 kilohertz, depending on age. In contrast, bats are capable of hearing sounds up to 110 kilohertz in frequency.
More than 800 species of bats use varying frequency patterns. Different bat species use particular frequency ranges according to their surroundings and type of prey. Scientists can identify various species by listening to the sounds of bats using bat detectors.Learn more about Bats
Bats can survive up to 24 hours without food or water. The exact amount of time depends in part on the bat's size, species, the time of year and whether it is nursing its young.Full Answer >
Bats use echolocation by emitting sound waves; when those sound waves hit a nearby object, it produces an echo that is then bounced back to the bat. The bat then deciphers the echo as the existence of an object in the direction from which the echo came.Full Answer >
Bats exit their caves in whatever direction is open to them, using echolocation both to avoid collision and to locate food. It is a popular myth that they always turn left, a legend that may have first surfaced via an email campaign in the 1990s.Full Answer >
Bats often roost in caves, but they can make use of almost any shelter. Some species make tents out of leaves, and others live in burrows made by other animals or in termite nests. Bats have even been seen roosting in flowers or in the webs of large tropical spiders.Full Answer >
