| Moths typically go into erratic dives when they sense that they have been detected by nearby bats using echolocation. |
| It's been known since the 1930s, with the discovery of bat echolocation, that animals can produce pitches too high for human hearing. |
| Using echolocation, ghost bats hunt for large insects, lizards, frogs, birds and even other bats. |
| Odontocete cetaceans rely upon echolocation to sense the environment and detect prey. |
| Like bats, dolphins use echolocation, an internal sonar system, to help them navigate, avoid predators and find food. |
| The ear is the most important sense organ for modern toothed whales, say scientists, because these whales locate their prey using echolocation. |
