In English, many things are named after a particular country – but have you ever wondered what those things are called in those countries?
- 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.
- Many odontocetes can navigate by echolocation, producing sound waves using a complex system of nasal sacs and passages, and using the echoes to navigate.
- You can imagine, for instance, the way certain animals use echolocation to find a target or source.
- Flying foxes use their excellent eyesight more than echolocation, or bouncing sounds, to locate their food at night.
- It's been known since the 1930s, with the discovery of bat echolocation, that animals can produce pitches too high for human hearing.
- 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.
- But their hearing and echolocation is the greatest almost of any animal.
- The rivers used by most platanistids are muddy, and these animals probably rely on echolocation more than vision to locate their prey.
- Like bats, dolphins use echolocation, an internal sonar system, to help them navigate, avoid predators and find food.
- This structure may help focus the sound emitted by these animals in echolocation and feeding.
- Some bats, for example, which navigate by echolocation, both emit and hear sounds with frequencies of more than 100 kHz.
- Toothed whales, such as dolphins, rely on this auditory sense when hunting prey by echolocation.
- 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.
- Moths typically go into erratic dives when they sense that they have been detected by nearby bats using echolocation.
- Bats are not the only animals that use echolocation.
- An additional explanation for the absence of either mode in Microchiroptera is their reliance on echolocation, and their need to maintain regular sensory input.
- 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.
- 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.
English has borrowed many of the following foreign expressions of parting, so you’ve probably encountered some of these ways to say goodbye in other languages.
