《窥视海豚》

　　制作了《窥视企鹅》背后的获奖团队再次出发，运用隐秘的摄像机进入海豚世界的心脏地带。通过隐藏在多达13只“间谍动物”身上的摄像机，在此之前从未出现在电视画面上的海豚的行为都被捕捉了下来；在这其中包括一个巨大的飞旋海豚群，在一边捕食灯笼鱼的同时还要积极躲避巨型蝠鲼的大嘴。

　　The award-winning team behind Penguins - Spy in the Huddle use hidden cameras to go into the heart of the dolphins' world. The camera eyes of thirteen different 'Spy Creatures' allow behaviour to be captured that has never been filmed before, including a vast superpod of spinner dolphins hunting huge shoals of lanternfish while dodging the gaping mouths of giant rays.
