CORE 2 FIRST TIMERS SO: DD-3 (I-L)

Bats’ brains can understand ultra-sound echoes incredibly fast! (in 2 to 3 millionths of a second.)

Being able to understand what their echoed sound is telling them very slowly is ok for the bats to not crash into one another.

Scientists discovered that some bats can change the shape of their ears in a tenth of a second.

Bats’ strange, spooky-looking ears have what are called ear leaves. These help hearing the returning echoes of their sonar.
