Synopsis

Le Grand Bleu de la haute mer constitue l'une des plus grandes régions sauvages du monde. Loin des rivages, d'une profondeur de plusieurs kilomètres, c'est un vaste désert marin où il y a peu nourriture et nul endroit où se cacher. Pourtant, il abrite certaines des plus grandes et des plus spectaculaires créatures sur Terre. Cet épisode dévoile ce qu'il faut pour survivre dans ce monde sauvage et inhospitalier.
