Definition of echolocation in English:

echolocation

nounˈɛkə(ʊ)lə(ʊ)ˌkeɪʃ(ə)nˌɛkoʊloʊˈkeɪʃ(ə)n

mass noun

The location of objects by reflected sound, in particular that used by animals such as dolphins and bats.
（尤指海豚和蝙蝠等动物使用的）回声定位
Example sentencesExamples
- The rivers used by most platanistids are muddy, and these animals probably rely on echolocation more than vision to locate their prey.
- Bats are not the only animals that use echolocation.
- Horseshoe bats have a special kind of echolocation (termed ‘high duty cycle’), which allows them to use the Doppler shift to detect the flutter of moth wings.
- Some bats, for example, which navigate by echolocation, both emit and hear sounds with frequencies of more than 100 kHz.
- It's been known since the 1930s, with the discovery of bat echolocation, that animals can produce pitches too high for human hearing.
- Toothed whales, such as dolphins, rely on this auditory sense when hunting prey by echolocation.
- Sharks have an acute electric sense with which they can detect prey, dolphins can detect characteristics of objects from a distance using ultrasonic echolocation, and crabs perceive water depth by sensing water pressure.
- For example, echolocation by bats and toothed whales is dependent on the sound transmission properties of air and water that can change with temperature or density.
- Flying foxes use their excellent eyesight more than echolocation, or bouncing sounds, to locate their food at night.
- Research suggests that noise from whale watching boats may interfere with the animals' echolocation and communication, making it more difficult for them to hunt for fish.
- Like bats, dolphins use echolocation, an internal sonar system, to help them navigate, avoid predators and find food.
- Many odontocetes can navigate by echolocation, producing sound waves using a complex system of nasal sacs and passages, and using the echoes to navigate.
- Moths typically go into erratic dives when they sense that they have been detected by nearby bats using echolocation.
- This structure may help focus the sound emitted by these animals in echolocation and feeding.
- You can imagine, for instance, the way certain animals use echolocation to find a target or source.
- But the whale's skull indicates it couldn't produce ultrasonic signals - meaning it didn't use sonar or echolocation, like some dolphins and certain whales do today.
- An additional explanation for the absence of either mode in Microchiroptera is their reliance on echolocation, and their need to maintain regular sensory input.
- But their hearing and echolocation is the greatest almost of any animal.
