Season 27

This is the story of a young giant otter's journey to adulthood. Rescued by local fishermen as a baby and raised by giant otter expert Carolina Vargas, this is the story of a young giant otter's journey to adulthood. At first, Sancho is utterly dependent on Carolina, and has to be bottle fed and taught how to catch fish. Eventually Carolina knows that she will have to break their extraordinary bond as Sancho makes his way back into the wild.

In the idyllic Pantanal, we follow Sancho's story as he learns to survive in a world fraught with danger.

Elle and Inga, 17-year-old cousins from the north of Norway, are far from ordinary teenagers. They are reindeer herders, equally at home helping reindeer swim fjords or ice fishing as playing with the internet and mobile phones.

Multi-millionaire landowner Paul Lister wants to turn his 23,000 acre estate north of Inverness into Europe's first wilderness reserve. Reinstating the old Caledonian pine forests is the first of his plans.

Some of the local people are far from convinced by Paul's vision. Will he even be allowed to let loose moose in the glen?

The story of Naabi, a young hyena growing up in Tanzania. Here hyenas aren't just scavengers, they're also skilled hunters when they work together in the clan. But life is still a struggle, and except for the few weeks a year when the wildebeest pass through, there isn't enough food to go around. Lions are their mortal enemies - they are quick to attack hyenas and often scavenge their kills. After Naabi's mother is killed by lions, life becomes even more difficult for the young hyena and she's forced to leave the clan, braving the perils of the outside world as she travels alone in search of food.

Paddington Bear celebrates his 50th birthday this year, but behind the children's story is a very real creature that still lives in Deepest Darkest Peru - the Spectacled Bear.

For years they were thought to be gentle vegetarians, but the latest studies reveal a new and alarming side to this endangered bear.

The billfish are the biggest, fastest, and most dangerous gamefish in the sea. All have captured man's imagination like few other creatures, whether it's the graceful sailfish, the menacing swordfish or queen of them all, the marlin, immortalized by Hemingway in 'The Old Man and the Sea'. Marine biologist and film-maker Rick Rosenthal has travelled three oceans in his attempt to capture them all on film, and in doing so has become a passionate champion for these endangered yet little-known ocean giants.

Documentary following a loggerhead turtle as she journeys across the Pacific. On the way she meets dolphins and whales, sharks and giant squids, typhoons and fishermen. She swims over deep canyons, and uses underwater mountaintops like motorway service stations. Blue whales thunder by like juggernauts, and sharks dance a beautiful midnight ballet around her. Pacific means peaceful, but it is clearly not. One minute she is under fire from marlin, the next swimming over a coral reef, with crocodiles as well as sharks.
