The hypothesis is that mantas use those fins to pick up electrical signals from other animals moving in the water .

这样就有了蝠鲼通过头鳍接受电位信号来感受水中其他动物运动的假设。

Sand mantas , most likely .

很可能是沙漠蝠鱼。

Cue Manta birostris . " Just after high tide you 'll see a few manta rays turn up ," says Guy Stevens , a British marine biologist who 's been researching the Maldives mantas for the past three years .

“高大的潮头过后我们能看到一些蝠鲼，”GuyStevens说道，他是一位研究马尔代夫蝠鲼三年之久的英国海洋生物学家。
