La planète des Géants - Episode Guide

On the Atlantic coast of the Valdes Peninsula in Argentina, killer whales have developed a unique hunting technique in the world. They run aground on the beaches, risking their lives, to snatch their prey. How did they acquire this know-how which is unique to them?

Off the coast of Mauritius, François Sarano dives with the greatest predators on the planet: sperm whales. He will get as close as possible to these "fifty tons of tenderness" ... until he dances with them!

In the water, a three-dimensional space, whales sing, killer whales whistle and dolphins click. What do they say to each other through these enigmatic sounds? François travels to the Bahamas to try to understand how dolphins use their echolocation ability to see the world and to communicate.
