 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. Killer 1 whales, the oceans'  top predator 2. Killers 3 are like wolves, for they will hunt animals far larger than themselves. But even smaller prey 4 are a problem, if you can't reach them. The solution is teamwork. Swimming in perfect formation, they flick 5 their tail in unison 6 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 quarry 7. A weddell seal. That is better. These are more docile 8 and easier to tackle. The pardon stay is close together and travels silently. This time they initiate 9 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.
