Whale vocab richer than thought

It cannot be language as we know it, but the whales do not have any shortage of ways to be done understood. So ample it is his vocal repertoire, in fact, that the whales can call to their young people, it courts potential companions and it even express emotions, according to the investigators who have identified 622 social sounds in whales of humpback. Its work will be presented/displayed in the next joint meetings of the acoustic society of America (HANDLE) and of the acoustic society of Japan in Hawaii. The social sounds are written, unpatterned the sounds that are different from songs more very long, complex of the whale. The new investigation adds to a body every greater time of the evidence than the whales transport more meaning with vocalizations than it thought previously. "It would not say (the whales have) language, as that is a human term," the news this Dunlop of the discovery of Rebecca. Dunlop, that worked in the study, is investigator in the school of veterinary sciences in the university of Queensland, Australia. The "whales do not chain these together sounds as words and orations of the form. It is rather a simple vocabulary," she said. The scientists visually followed 60 cases of the whales that emigrated throughout the coast of the east of Australia. The investigators used an arsenal of static hydrophone - sensible equipment that detects acoustic waves - to bind to the sounds of the whale to the several activities and contexts. They identified 622 different sounds, that fell in 35 basic types. These include "wops" done by the females, "thwops" done by the men, the "barks" made when the cases start off, and the shouts acute that appeared to express rage. In addition to vocalizations, the investigators found that the whales send messages with body language - practicing an opening the surface, giving a pat to the water with their tails and blowing subaqueous bubbles. Famous by your long, complex songs, whales also "to speak sometimes" the short units of the song individually instead of singing them. The men specially look like to make this when trying court a female. The "song is a noisy signal of the diffusion and two singers who sing at the same time are limited to be confused the receiver," Dunlop speculated. "If he is trying to attract a female, but it does not wish its signal confused with another singer in the area, then to use units of the song in this case could be the way advanced." She thinks that they are the whales of a reason so vocal she is because the sound travels better in water than light, and so the Vista is less useful to the whales that the hearing. Christopher Clark, director of the research program of Bioacoustics in the university of Cornell, lead a similar study in right whales. It needed the irony that hardly as the investigators are gaining a better understanding of vocalizations of the whale, the human beings is creating as much noise of the ocean - with the shipment, exploration of the oil and the gas, recreacional traffic and more than we often avoided that the whales communicate. "Many whales have very traditional arguments of feeding and his migratory routes to happen throughout the low lines of the coast, that now are something of noisiest, the possible habitat more heavy affected," he said. "The excess of the area of the ocean that a whale can communicate and listen today has shriveled to a small fraction down of which it was less than a century ago."

Maybe the disturbance in communication explains for whales throwing themselves on shores.
