鲸鱼竟乃自然界"歌王" 能连续唱一天

  Each song lasts for ten to 20 minutes and the males can sing continuously for 24 hours. At any one time, all the males in a population sing the same song. But a study, published in the journal Current Biology, shows that this song changes over time and spreads around the oceans. Dr Ellen Garland, of Queensland University, said: ‘Our findings reveal cultural change on a vast scale. Songs move like cultural ripples from one population to another, causing all males to change their song to a new version.’

  据悉,鲸鱼们唱歌课不轻松,一首曲子至少能维持20分钟,而且雄性座头鲸常常能唱歌长达24小时。科学家发现,在任何时间,雄性座头鲸都会“演唱”同一首曲子。在一本期刊《当代生物学》发表的研究上指出,这首座头鲸唱的曲子在全世界通用,在任何海域都能听得到。可谓在鲸鱼界“不分地域”“享誉全球”的曲子。有专家Dr Ellen 说:“我们的研究目的是表明一个道理,那就是文化交流是在任何一个物种之间都存在的。”
