巴西科学家通过录音明显地听到了河龟在水下交谈的声音。这些河龟在做不同的事情时会发出不同的声音，它们也会选用不同的声音来和成年龟或幼龟交谈。野生动物保护协会的研究人员认为这些河龟很可能是在使用声音来交流信息。以下是 BBC 记者 Victoria Gill 发回的报道:
This muffled creak is what researchers heard repeatedly when they listened to giant South American river turtles swimming together. It could help explain how the animals coordinate their behaviour so well in the nesting season, when females gather in large groups at beaches before laying their eggs.
The researchers used microphones above and below the water to record the turtles at different stages in the season. And when the newly hatched turtles and adults were together in the river, scientists heard a different sound.
This, they think, is parents guiding their newly hatched babies on their first migration. Also the researchers say that their study also shows how vulnerable turtles could be to man-made noise disturbing this quiet but seemingly vital chatter.
