イルカは名前を認識する?
A new study indicates that dolphins recognize names--their signature whistles--even when voice cues are removed from the sound. Scientists studying bottlenose dolphins(バンドウイルカ) in Sarasota Bay, Florida, synthesized signature whistles with the caller's voice features removed and played them through an underwater speaker. The dolphins would turn more often toward the speaker if they heard a whistle that sounded like a close relative's.
