The technique also forms the basis of the hunting songs of the 73 species of cetaceans with teeth, collectively known asThey use this process to bounce sound waves off the surroundings in the dark, as deep as two kilometres beneath the waves, and so detect their prey. “While vocal fry may be controversial in humans and may be perceived as everything from annoying to authoritative, it doubtlessly made toothed whales an evolutionary success story,” he said.
Andrea Ravignani, of the Max Planck Institute for Psycholinguistics, in the Netherlands, who was not involved in the study, said: “This study reveals that toothed whales can display extraordinary vocal abilities while diving at 1000 meters and feasting on seafood. At least vocally, humans are not so special after all.”
Overall, the researchers reveal that toothed whales have a wide vocal range, akin to that of a human, with three distinct vocal registers, just like humans. The registers are key because they allow toothed whales to convey a host of emotional and complicated languages in the upper registers, at high frequency, as well as to blast out really loudly at much lower frequencies at five times the volume of any trumpeter, making the loudest noise of any animal on the planet and without damaging their lungs.
