Hidden Japan

National Geographic: Tsunami - Killer Wave

The globe learned on December 26, 2004, that tsunamis can bring death and devastation to the world's coastlines. The product of undersea earthquakes and volcanic eruptions, tsunamis can race across oceans at more than 500 miles an hour, leaving a huge wake of destruction when they hit shore. Because it is difficult for scientists to predict how large these massive waves can be, tsunamis are one of the least understood of nature's forces, and one of the most dangerous. With insight from some of the scientific community's foremost researchers, and vivid accounts from past tsunami survivors, Tsunami: Killer Wave depicts nature at its most extreme, profiles the efforts being made to curb its effects, and illustrates the financial, physical and emotional toll it can leave on its victims.

Extreme Animal Weapons

NOVA: Extreme Animal Weapons From lobster claws and dog teeth to bee stings and snake fangs, every creature depends on a weapon. But some are armed to extremes that make no practical sense - whether it's bull elks with giant 40-pound antler racks or tiny rhinoceros beetles with horns bigger than their body. What explains giant tusks, horns and claws that can slow an animal down and even impair health and nutrition? Showcasing astonishing wildlife cinematography, Extreme Animal Weapons investigates the riddle of outsize weaponry and uncovers a bold new theory about what triggers an animal arms race. In creatures as varied as dung beetles and saber-toothed tigers, shrimp and elephants, the same hidden factors trigger the race and, once started, these arms races unfold in exactly the same pattern. In this enthralling special, NOVA cracks the secret biological code that underlies nature's battleground.

Antarktika - Die gefrorene Zeit

The bleakness of Antarctica is a fallacy. The ice continent is full of life and offers a biodiversity of which only about two percent are known. Much of it is under water and could determine the future of human beings. When the northern lights cover the ice landscape in summer, the animals in the Antarctic are in a paradisiacal state. Whales blow their fountains in the sky, penguins fly like small rockets into the water, seals dive for crabs under the glittering ice floes. From the bay of the Ross Sea to the ice shelf, from the huge penguin colonies to steaming volcanoes, a life in rhythm with the ice. But the consequences of climate change are slowly becoming apparent here too. While some species are dying, others are spreading. They could bring new viruses and bacteria with them, and new dangers for humans too. The structure of nature has gotten off course. How many generations will still be able to experience the magic of Antarctica?

La Marche de l'empereur

Every year, thousands of Antarctica's emperor penguins make an astonishing journey to breed their young.

Breathtaking photography captures the transcendent beauty and staggering drama of devoted parent penguins who, in the fierce polar winter, take turns guarding their egg and trekking to the ocean in search of food. Predators hunt them, storms lash them. But the safety of their adorable chicks makes it all worthwhile. So follow the leader... to adventure!!

700 requins dans la nuit

Gombessa Expedition 4 Laurent Ballesta went to observe a gathering of thousands of groupers during the full moon of June 2014 (Le mystère mérou) in the southern pass of the Polynesian atoll of Fakarava, where he discovered a pack of over seven hundred grey sharks. How can this unprecedented density be explained? Could it be that social behaviors govern this wild horde? During three years of preparation, he and the other divers on his international scientific team tamed their fear by abandoning the defensive reflexes that provoke shark aggression, with the aim of slipping into the heart of the raging pack to study and film it from the inside. Sharks fitted with microchips, receiving antennas, hydrophones, an ark of 32 synchronized cameras...: a whole technological arsenal is mobilized for the project. As the groupers approach for their annual spawning, what battle plan will the sharks deploy?
