The remora is an unusual fish. It hitchhikes on other sea creatures using a sucker on its head.

印鱼是一种不寻常鱼。因为它会用头上吸盘，搭乘其他海“便车”。

The researchers set out to replicate the remora's energy-saving strategy by recreating its sticky disc.

研究人员着手通过重新制作其粘盘来复制 remora 节能略。

Remoras save energy by sticking to all sorts of surfaces– from the hard shell of turtles to the rough skin of sharks.

Remoras 通过粘在各种表面上来节省能量——从海龟硬壳到鲨鱼皮肤。

While remoras burst out of water by attaching to other swimmers, some animals, such as the kingfisher, can propel themselves into water and out of it– snagging prey along the way.

虽然鲇鱼通过附着在其他游泳者身上而冲出水面， 但一些动，如翠鸟，可以将自己推进水中和水中， 沿途捕捉猎。

Making something that works like a remora's disk will help us better understand how they work and could one day lead to useful underwater devices based on the same principles.

制作像雷莫拉磁盘一样工作东西将帮助我们更好地了解它们工作原理，并且有朝一日可能会基于相同原理开发出有用水下设备。
