Bats can detect insects they consume as food, up to 18ft. away, and can gather information about them by using their echolocation sense.

I Sense Dinner Is Ready

We should all be lucky enough to have the sense of a bat, at least their auditory sense. If we did, we'd never lose glasses, keys, or anything else. All we'd have to do is stand in the middle of a room and hum or click our tongues to locate the things we misplace.

Of all the bats in the world, a sub-order of the species called microchiroptera, have a special skill known as echolocation. This sound/audio sense is used by more than 800 varieties of bats in the sub-order.

If you start out with the right type of bamboo for your temperatures, soil composition and moisture, you can soon be enjoying a lush, "exotic" greenery that will grow and spread faster than you could ever have imagined.

Each variety will issue its own peculiar vocal signals, that we will never hear, because they are in a KHz range that is beyond the human ear. Depending on the species, the bat's own auditory system may be geared to a specific range such as the 60-61KHz bracket used by the moustached bat.

Like human ears, the bat's ear has a basil membrane in the cochlea that vibrates when receiving sounds and transforms the vibrations into neural signals. But unlike humans, that membrane will be thickened in the exact areas that would best perceive a given range of KHz. Researchers have even discovered that the ganglion cells of the brain can also by hyper-developed to receive signals of a specific KHz.

Bats use their echolocation to gather information on many things, primarily the insects that make up their diet. By issuing a sound, and receiving back signals created by the sound bouncing off the insect, a bat can tell their location, size, how fast they are moving, and whether they are fluttering.
