Each sea lion needs over 6kg of fish a day.

每头海狮每天需要超过六公斤鱼

With shoals this size, it shouldn't be too difficult.

鱼群如此庞大，似乎并非难事

But it's not easy picking one fish out of the crowd.

但要从鱼群中抓到一条并不容易

The fish know there's safety in numbers,

so for the sea lions, the trick is to snip the shoal into smaller and smaller balls.

海狮的对策便是不断把鱼群分离缩小

Finally, a fish breaks for cover.

终于，一条落单的鱼寻求隐蔽

It's what the sea lions have been waiting for.

这便是海狮久等的机会

Crevices in the reef might seem to offer shelter.

礁岩中的缝隙是不错的藏身处

But that's no problem for the sea lions, who simply scare them out with bubbles.

可这根本难不倒海狮，吹吹气泡就能把它们吓出来

With the sea lions distracted, the fish regroup and the chase starts all over again.

趁着海狮转移注意力，鱼群再次整编，追捕又要从头开始。
