但从它们的视角去体验这个世界
But experience the world from their perspective,
你会发现当大块头并非易事
and you'll see it's not easy being huge.
动物的体型越大 风险就越大
The larger the animal, the higher the stakes

但有一种海洋巨兽在这方面 比任何其他动物都要更甚一筹
But one ocean giant goes further than any other.
(旁白 汤姆希德斯顿)
和一辆巴士一样长
As long as a bus,

然而 尽管这个温暖 隐蔽的墨西哥海湾
But while this warm, sheltered bay in Mexico
似乎是哺育幼崽的理想之地
seems an ideal place to raise a calf...
这里却没有什么妈妈能吃的东西
there's nothing here for Mum to eat...
它正慢慢地忍♥饥挨饿

不然妈妈就没力气活着抵达目的地了

它带着自己的小巨兽从安全的育儿室出来

进入广袤无垠的蓝色海洋

它的下一餐仍然远在千里之外

一群海豚游到它们掀起的波浪中嬉戏
