As they say fish? Questions and answers on physics

Who? What? Where? How? Where? When? What?

Why? What? How much? “Yes” or “no”?

MUTE AS A FISH?

Physics note.

Fish extract sounds when the friction of the Gill plates. Carp grind their pharyngeal teeth. Very interested in a sound machine percidae, especially developed at the singing fish and sea cock – trigly. The sounds are produced only with the help of the swim bladder, due to the reduction in the particular drum of the muscles that cause fluctuations in its walls.

Where would she get these sounds?

It turns out, talking to each other fish. The scientists were even able to establish which of the sea creatures what a voice.

Later, it became clear that some of the fish extracted sounds when the friction of the Gill plates. And cyprinid fishes grind their pharyngeal teeth. Interested in a sound machine percidae, especially developed at the singing fish and sea cock – trigly. Here the sounds are produced only with the help of the swim bladder, due to the reduction in the particular drum of the muscles that cause fluctuations in its walls.

Camabatela sea fish was Trigla – the sea cock. She constantly grunts and croaks. Black sea horse mackerel barking like a dog, and the sounds, which publishes the mullet, like the clatter of horses ‘ hooves.

African casuistic meows like a cat. Beluga, for example, emits a loud heavy sigh, resembling a roar, and Beluga whistle and hiss.

It turned out that there is no fish or sea animal, which would each in their own way not talking.

Talking and other numerous marine life: crabs, shrimp, and various shellfish. For example, pink shrimp POPs, lobster creak, rubbing his antennae on the shell. But the voice of the shrimp Alpheus resembles the sound of a cork flying out of bottle.

Fish there are more “talkative”, and less “chatty”. Some emit high frequency sounds that are inaccessible to the human ear.

Mostly fish give each other signals about the whereabouts of food; warn about the dangers; that is the place from where they are at present; of the direction of motion, and furthermore, males and females give each other special signals during spawning.

It is noticed that in the summer, closer to the twilight sound activity of aquatic life increases, reaching to 9 p.m., the loud sound.

Here to you and “it”!
