Insect-eaters Rely on Echo-location
The Microchiroptera (insectivorous bats) are characterised by small eyes, sharp pointed teeth, and strangely-shaped ears, while many also have bizarre nose structures. Seen up close, most appear somewhat frightening and this appearance has contributed to their unpopularity among many people (see below).
Able to find their way and hunt in complete darkness, insect bats employ ultrasound (inaudible to the human ear) to navigate by echo-location. A call or chirp is made and then "read" as it is reflected back to the animal's highly sensitive ear receptors.
