（单词翻译）

 Every hunt presents a different challenge, so he plans a new strategy each time. He slinks into the water, using a channel between the ice floes to act as cover.

 
He swims, hardly making a sound, reaching six miles per hour at times. His front legs provide propulsion, while his back legs steer2. His low profile makes him seem like a floating sliver3 of ice. He checks the seal's position and takes 
 
wind direction into account to work out his final approach. As he closes in, he makes a clever move, diving deep beneath the ice floe1. He emerges on the blind side of the seal. 
 
So far, so good.
 
He can hold his breath for minutes and calculate the seal's exact position. 
 
Slo-mo reveals just how close he got. His skills show a remarkable4 intelligence at work. He hunted in all three dimensions, making full use of the opportunities offered by water and ice.
