摘要
1 Move over Simone Biles,because grey whales might just be the next Olympic champions.This conclusion can be drawn from a new study that filmed these amazing animals doing underwater headstands(头倒立)and other moves.2 As part of a seven-year project,scientists used drones(无人驾驶飞机)to observe a group of 200 grey whales off the coasts of Oregon,Washington,northern California and southern Canada.The new study findings,published in Animal Behaviour,revealed that grey whales do headstands by pressing their mouths against the ocean floor while searching for something to eat.Scientists also noticed that when doing headstands,grey whales move like human synchronized swimmers.
答案与简析本文是一篇说明文。新研究表明,灰鲸会通过水下倒立等高难度动作来觅食。此类行为不仅体现了灰鲸的环境适应能力,更揭示了其觅食策略会随身体发育阶段的改变和海洋环境的变化而进行动态调整的生物学特征。
