A professor develops an extraordinary relationship with an octopus when he invites it to live in his home. The octopus, called Heidi, unravels puzzles, recognises individual humans and even watches TV with the family. The episode also shows remarkable behaviour from around the world - from the day octopus, which can change colour and texture in a split second, to the coconut octopus, which carries around its own coconut shell to hide in. But most fascinating of all is seeing how Professor David Scheel and his daughter Laurel bond with an animal that has nine brains, three hearts and blue blood running through its veins.

The beauty of the Arctic is breathtaking. For as long as we can remember, the Arctic has been associated with inhospitable cold. But the climate is changing, and with it the northern polar region, which begins beyond latitude 66.5 degrees north. Climate change is now happening four times faster north of the Arctic Circle than on the rest of the planet, making the future outlook dire. At the moment it is still possible for polar bears to raise their cubs, but hunting is becoming increasingly difficult on the drastically shrinking pack ice. The disappearance of the ice also affects the marine fauna. The wintry ice bridge between Canada and Greenland is threatened with collapse. The unstoppable melting of the permafrost, which has held the tundra together for thousands of years, is worrying. But the Arctic is still one of the wildest and loveliest regions on earth. A documentary visit to the Arctic - as long as it still exists.

Since the summer of 2020, boats along the Atlantic coast from the Strait of Gibraltar to the Bay of Biscay in the north have been repeatedly attacked by orcas. The whales purposefully attack the rudders and destroy them. Researchers are trying to find out what drives them. Curiosity? Competition for food? Or play?

An exploration of the diversity of moths and butterflies from caterpillars to larvae to chrysalis to winged flight. The documentary covers camouflage and other anti-predatory tactics along with uniqueness of different species and amazing feats and colors.

Feature-length documentary following award-winning wildlife cameraman Vianet Djenguet as he documents a gruelling but vital mission to ‘habituate’ a notoriously protective 450lb silverback, in a last-ditch effort to save the critically endangered eastern lowland gorillas from extinction.

For the animal and plant world that lives there, the Kalahari is a region as grandiose as it is unforgiving. For a long time it was thought that only the law of the strongest could survive here. But a completely different strategy is needed: cooperation.

Using original footage and interviews, this documentary tells the nail-biting story of Apollo 13 and the struggle to bring its astronauts safely home.

Shark expert Neil Hammerschlag and a crew of researchers search for an elusive hammerhead shark.

In southern Germany, winter can still be admired in all its glory every year. With its white coat of snow and icicles and myriads of small crystals that look like geometric works of art. In the valleys and on the slopes the snow is still so thick every year that the alpine huts are snowed in up to the windows. Cows and dairymen are safe in their farms at lower altitudes. But not the wild creatures of the mountains! They need strategies to survive the cold season and to defy snow masses, cold and ice. And some seem to do it so easily that they even raise their young in the middle of winter. But how do animals, plants and fungi cope with the annually recurring ice age, which from our perspective is a time of need? The many adaptations in nature prove that winter is an integral part of the natural cycle of the year and the living environment of species. They are adapted to cold and frost. That is why the animals and plants at the edge of the Alps suffer particularly from climate change!

The white chalk cliffs of Rügen are among the most impressive natural monuments on earth, which the painter Casper David Friedrich immortalized for posterity as early as the 19th century. Germany's largest island with its seaside resorts from the Gründerzeit, its smaller side islands and peninsulas that give it its shape, its lagoon-like Bodden waters, the dense beech forests, the yellow rapeseed fields and the meadows, the shady tree avenues and the white sandy beaches is not only a magnet for tourists, but also a unique natural paradise in the middle of the Baltic Sea, a habitat for the rare white-tailed eagle, fallow deer, raccoon dogs and badgers as well as a resting place for huge swarms of migratory birds such as geese and cranes that can be heard trumpeting from afar. In this nature documentary, the unique landscapes and the diversity of the animal world of Rügen are captured with beautiful pictures during the changing of the seasons.

Carried by an immersive sound environment that plunges us in the reality and the perceptions of these resilient and inspiring people, this film questions our own blindness face to violence and suffering of our time — despite the overabundance of images that reach us — and highlights the urgency of lending an ear to hear these stories.
