Echolocation Mechanisms in Bats and Toothed Whales
Quick fact
Bats and toothed whales both echolocate, but they generate their sonar signals in completely different ways: bats emit high-frequency calls from their larynx or tongue, while toothed whales produce clicks by forcing air through nasal structures—yet both achieve a remarkably similar 'sound picture' of their world.
Why this is interesting
Picture a bat swooping through a pitch-dark cave and a dolphin hunting in murky ocean water—both moving with impossible precision. How do they 'see' with sound?
