The Quiz: What navigational tool do some whales share with bats?

Echocardiogram
GPS
Echolocation
Audiotelepathy

Toothed whales (but apparently no species of baleen whales) use echolocation to hunt their prey, emitting high-pitched sounds and interpreting the sound that bounces back to them. To help amplify the sounds, whales that use echolocation have evolved oddly shaped asymmetrical skulls, plus a layer of extra soft tissue on their head called a melon. The technique, shared with bats, is so accurate scientists studied it to develop radar and sonar technology.

The correct answer to this quiz is Echolocation.
