Sea Hunters

Every spring in Norway, whales use a clever hunting technique called bubble feeding to catch quantities of herring. When they spot a shoal of herring, they begin to encircle the herring, periodically releasing streams of bubbles that form a curtain of air, surrounding the fish.

Marine biologists Eve Jourdain and Richard Kaoliussen have spent two years studying the orcas in Norway, where they have adapted the carrousel technique to their habitat.

In the depths of the ocean, swift and agile sea lions perform incredible underwater maneuvers to outwit their enemies. Here, on the beaches of Patagonia, as a sea lion pup learns to swim, predators are preparing an attack on him, one that will be fatal.

Cape Gannets are tough hunters flying over the coasts for their favorite prey: shoals of sardines, waiting for a surprising ally: dolphins.

Under the burning sun of Cape Cross, large colonies of seals gather on Namibia's Skeleton Coast...The males, who can weigh up to 360 kg, patrol the territory to protect their females and young. But new predators are coming from the land, forcing them to learn new defense behaviors.

In the heart of the Valdees Peninsula, in Patagonia, whales are regularly hunted by a predator whose diminutive size hides its gruesome intentions: the seagull, forcing whales to dive deep into the depths, away from essential oxygen and light.
