Special ultrasonic AC frogs (map)

Huangshan discovered concave-eared torrent frog

The journal nature on its ear structure that helps in the treatment of human hearing loss

According to the journal nature reported that scientists in Huangshan finds a very special frog, to communicate between them by issuing an other animals cannot hear ultrasound, this is the first mammals other than animal able to communicate with ultrasonic to. Scientists think that this is a new independent evolution of the example. Through this frog ears special structure, helped to invent a new technology to help people in there are a lot of background noise environment to hear voices heard.

Huangshan frog occur unusual evolutionary, to manufacturing and can hear ultrasound

Huangshan in this frog why there will be through the strange phenomenon of ultrasonic AC? this is because they live in a particular environment, such as sound great falls and Rapids, these voices could steamroller calls the largest frog sounds. In this case, the frog has evolved slowly, they are no longer solely on ordinary sounds to convey information, but rather to communicate using ultrasound to, this is a clever way, is also a kind of let scientists surprised evolution. According to the United States, Illinois University neuroscientists Professor Albert · Feng said: "this phenomenon shows up with a new independent evolution of examples, great background noise environments, this frog is the evolution occurred in particular. ”

This frog is concave-eared torrent frog, which lives in the mountains covered with forests, mountain hot spring area, most of the time is near the rapids of the waters of life, where the water is usually very calm and very brief, but when it rains, the water a few feet deep, hit the river's big rock loud sounds, plus a small waterfall sound, the sound of the frog almost inaudible. Professor Feng said: "If these frogs like to communicate, they have two options, one option is to send very large, another option is to change the frequency of the sound, to distinguish the background noise. "However, the first choice is clearly unfavourable to them, first issued in respect of ultra-high of must continue for a long time, this can consume a lot of energy, but also very difficult for a long time, in addition, this kind of out there is no doubt on their life is a dangerous, and their enemies will be easier to hear their cries and will they eat. So, after a long evolution, they are able to manufacture and to hear most of ultrasound, and other animals are not hear this sound.
