Lesson 7-2  Bats

Every solid objectwill reflect a sound, varying according to the size and nature of the object. Ashoal of fish will do this. So it is a comparatively simple step from locatingthe sea bottom to locating a shoal of fish. With experience, and with improvedapparatus, it is now possible not only to locate a shoal but to tell if it isherring, cod, or other well-known fish, by the pattern of its echo.

It has been foundthat certain bats emit squeaks and by receiving the echoes, they can locate andsteer clear of obstacles -- or locate flying insects on which they feed. Thisecho-location in bats is often compared with radar, the principle of which issimilar.
