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 ...
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 ...
4. True or false: Female blue whales are actually larger than males. True. Female blue whales are actually larger than males, and the largest specimen ever recorded was 98 feet (29.9 meters) in length and weighed 219.4 tons (199 metric tonnes). Read More: What's the Largest Land Animal...
Plotting out an attack on a group of insects may sound borderline crazy, but you'll have more success if you plan ahead. To do that, let's go back to those three things that roaches need: warm areas, food residue, and water. Taking away those elements is like serving them an ...
