海龟英语怎么说 海龟用英语怎么说呢( 三 )


但事实上是科学家们没能听仔细 。近年来 , 生物学家已辨别出海龟至少有11种声音 , 并将这些声音录了下来 。这些声音有的录自水里 , 有的录自陆地 。那么 , 它们的含义又是什么?
In the latest attempt to decode turtle talk, researchers tailed giant South American river turtles—Podocnemis expansa—in Brazil, over a two-year span. They recorded 220 hours of audio, capturing six of those 11 sounds. Two of the calls were extremely common—occurring during just about every turtle activity. Other calls the turtles made only during migration, or while nesting at night <>. The findings appear in the journal Herpetologica.
在新一项研究中 , 研究人员为解读乌龟的声音 , 对南美巴西的一只巨河龟——侧颈龟展开了逾期两年的追踪 。他们录下了长达220个小时的音频 , 并捕捉到上述11种声音中的6种 。其中两种声音很普遍——几乎出现在所有的海龟活动中 。而其他声音则是在海龟迁徙或晚上睡觉时发出的 。该研究结果发表在《蛙蛇学报》上 。
The researchers still aren't sure what any of these sounds actually mean, or whether turtles can recognize each other by voice alone. All the more reason, they say, to use these sounds in playback experiments, which might get these talking turtles out of their shells.
