By blowing air through the voice boxes, scientists identified the tissues that vibrate (震动) and even created computer models to match them to recordings of similar whales taken in the wild.(这项由南丹麦大学的Coen Elemans领导的研究包括检查鲸鱼的喉舌,并在实验室中进行实验。通过将空气吹入音箱,...
Bats usually fo llow sound waves to communicate. Birds com municate through their chirping(唧唧叫).Mamm als generally use sounds to give calls to other members of their community and whales are g ood at using sound waves.Besides sounds, facial erpressions are als o used by animals. For ...
Research has shown that certain animals, like birds and whales, can exhibit variations in their calls and songs depending on their geographical location, much like humans have accents based on where they’re from. Can fish communicate through sound? Yes, fish can communicate through sound. They ...
Many species of whales slap their tails on the water’s surface, possibly for predation and communication purposes. Known also as lobtailing, humpbacks will slap the water vertically with their tail. The sound produced from the action can travel miles under the water, indicating that communication...
Whales don't produce sounds the way we do. Our vocal-cord system wouldn't work too well underwater. Instead, whales produce sound by moving inhaled air around the nasal cavity in front of their blowholes. In toothed whales, the sound-making system involves a complex arrangement of fatty tis...
First, the whale has to produce a sound. Toothed whales don't have anything exactly like our vocal cords, although they have similar structures. It's thought that they produce their sounds in their nasal passages [source: Hebridean Whale and Dolphin Trust]. The melon, the fatty structure we...
Like other toothed whales, dolphins also rely upon sounds for communication. One reason might be that sound waves travel almost five times faster through water than through the air. Dolphins produce two kinds of sounds:whistlingandclicking. Dolphins primarily generate clicking sound forecholocationor ...
How are whales affected by underwater noise pollution? Why are sound waves called pressure waves? How does sound pollution affect biodiversity? How do insulators help conductors? What happens when a sound wave moves from water to air? Why do liquids flow and solids...
● Do the map reading if you're being driven somewhere. It'll be easier if you keep turning the map so it follows the direction you' re traveling in. Keep looking ahead so that you can give the driver lots of warning before having to make a turn, or you'll have to move to the ...
sperm whale, you spend half your life in the pitch black of the deep sea, hunting squid by ear. you use sound to speak, too, just as humans do. but your voice, rather than dissipating instantly in the thin substance of air, sustains. some whales can shout louder than a jet engine,...
