Negotiating the channel is her first challenge.
它的第一個挑戰是游過水道
The water near the mouth of the pool is slightly deeper.
水池開口處附近的水深較深
Here she sets her ambush,
它在這里準備突襲
waiting for a seal to stray out of the shallows.
等候遠離淺水處的象海豹出現
For mother and calf, this is an extremely risky ploy.
對殺人鯨母子來說 這種作法風險極高
She must continuously assess how big the waves are, how deep the water is
它必須不斷評估浪的大小
and what the tide is doing.
以及水深和潮汐
One bad decision would see both mother and calf stranded.
一個錯誤決定 就可能讓它們母子受困淺灘
The seals lie in the shallows,
躺在淺水池的象海豹距離太遠
just out of reach and unaware of her presence.
也不知道母鯨在這里
But she is more than aware of the dropping tide.
但母鯨很清楚現在已經退潮
A floundering seal catches her attention...
一只涉水的象海豹引起它的注意
..and with her calf, she slowly moves towards it.
它帶著幼鯨緩緩逼近
The seal is lying right on the edge of a rocky ledge,
象海豹躺在一片巖架邊緣
oblivious to the danger.
渾然不覺危險將至
