Humans have their difficulty communicating with each other in the same language. Using a different language multiplies the difficulties ten fold. Now dolphins have their own way of communicating and, at times, seem to vaguely understand humans. The scientific community had thought that whistles were the main sounds made by these mammals, and were unaware of the importance and use of burst pulsed sounds. Researchers from the Bottlenose Dolphin Research Institute (BDRI), based in Sardinia (Italy) have now shown that these sounds are vital to the animals’ social life and mirror their behavior.
