（单词翻译）

 The randoms of the sea ice are occupied by sun- bathing seals that have been here all winter. But the new arrivals're following the retreating ice edge and they have come here to hunt. Killer1 whales, the oceans'  top predator2. Killers3 are like wolves, for they will hunt animals far larger than themselves. But even smaller prey4 are a problem, if you can't reach them. The solution is teamwork. Swimming in perfect formation, they flick5 their tail in unison6 and create a wave that cracks the ice. They regroup and access the damage. 

 
A more powerful wave is needed. The ice float is breaking up. Now they are close enough to get a good look at their target. The seal is a crabeater , sharp to stand feisty, not their favorite. The wolves of the sea move on in search of easier quarry7. A weddell seal. That is better. These are more docile8 and easier to tackle. The pardon stay is close together and travels silently. This time they initiate9 far more powerful wave and with astonishing accuracy. These big whales are not intended to break the ice, but to knock the prey into the water and they rarely fail.
