殺人鯨會跳出水面，有些鳥類又會潛到20多米水底……有些動物就是會毫不猶疑地走進不熟悉的環境。在阿根廷馬德林港的海灣外，荷基．卡澤納夫會向我們解釋殺人鯨的擱淺技巧；而在南非的蘭伯特灣，海洋生物學家洛里安．皮切格魯會研究南非鰹鳥的捕食技巧，為了捕獵沙甸魚群，牠們最深可以潛到20米海底。原來這種捕獵方式，是雀鳥和海豚跨品種合作的結果。

Orcas that come out of the water, birds that dive to depths of over twenty metres… Some animals don't hesitate to enter unfamiliar environments.

In Argentina, in the bay off Puerto Madryn, Jorge Cazenave will explain the orca beaching technique. In Lambert’s bay, in South Africa, Lorien Picehegru, marine biologist, studies the hunting techniques used by the Cape gannet, which can dive as far down as 20 metres into the water to reach shoals of sardine. We shall learn that this hunting method is the result of interspecies cooperation between birds and dolphins.
