For the animals in the polar regions, autumn means dramatic battles and epic journeys. Time is running out - the Arctic Ocean is freezing over and the sea ice is advancing at 2.5 miles per day around Antarctica. Polar bears gather in large numbers on the Arctic coast as they wait for the return of the ice. Soon, tempers fray and violent sparring contests break out. Meanwhile 2,000 beluga whales head for one special estuary, a gigantic 'whale spa' where they will thrash their snow-white bodies against the gravel and exfoliate. Inland, the tundra undergoes a dramatic transformation from green to fiery red. Here, musk ox males slam head-first into each other with the force of a 30mph car crash as they struggle to defend their harems. Frisky young caribou males play a game of 'grandma's footsteps' as they try to steal the boss's female. Down in Antarctica, Adelie penguin chicks huddle together in creches. When a parent returns from fishing, it leads its twins on a comical steeplechase - sadly there's only enough for one, so the winner gets the meal. Two months later and the chicks are fully feathered apart from downy Mohican hairdos - they're ready to take their first swim - reluctantly though, as it seems penguins are not born with a love of water! And with good reason - a leopard seal explodes from the sea and pulls one from an ice floe, a hunting manoeuvre that has never been filmed before. As winter approaches and everyone has left, the giant emperor penguin arrives and makes an epic trek inland to breed. The mothers soon return to the sea leaving the fathers to hold the eggs and endure the coldest winter on earth.

A unique celebration of one of Earth's most iconic birds. For the first time, we meet the entire penguin family - all 18 species. This colourful cast of characters may seem familiar, but their incredible diversity won't fail to surprise. New Zealand's lush green forests might not be the first place you would expect to find penguins, but it was here the penguin family first evolved 60 million years ago, and there are now more species living here than anywhere else on earth. One quirky-looking resident is the Snares penguin, which likes nothing more than a spa treatment. In Cape Town, the African penguin has adapted to the modern world, strolling the city streets with all the other commuters. And, against all the odds, one of the smallest members in the family, the Galapagos penguin, has found a way to survive the sweltering heat of the equator. One of the biggest secrets to the penguin success story is their remarkable parenting skills. Adelie penguins perform the longest penguin migration on earth, over 6,000 miles, to find the perfect nesting site. Ninety-nine per cent of them return to the same nests each year, but after a hard winter their stone nests need some serious renovation. Other species are sneakier, stealing their neighbours stones the moment they turn their backs. The fastest penguin on the planet is the gentoo, reaching speeds of 22mph and diving to 200 metres. Short feet that act like rudders and a streamlined body allows them to shoot through the water, while fused muscular wings act like paddles. Penguins are supremely adapted to an aquatic life, spending 75 per cent of their lives in water, but all penguins have to walk at some point, so to get around they have developed the infamous waddle. This bizarre locomotion may look inefficient, but surprisingly it actually works in their favour. Whilst we get 65 per cent of the energy back with each step, penguins can get up to 80 per cent, so the waddle is more efficient that our own walk. Over millions of years, penguins have mastered life on land and in the sea, but we are now changing the planet faster than ever before, and some penguins are struggling to keep up, so technology is being used to locate and observe new colonies from the equator to Antarctica. This is the family penguin as you have never seen them before.

A look at wildlife in hostile environments, including glow-worms, condors, thorny devils, emperor penguins and polar bears. High in the mountains, deep underground, out in the deserts and at each of our vast frozen poles, animals have had to develop extraordinary resilience to survive. There are many challenges faced by animals living in extreme environments. Superbly adapted to these inhospitable habitats, their fortitude and resilience.

The sea turtle is one of the oldest animals on Earth. These ancient mariners pre-date the dinosaurs and have existed for over 100 million years, but now all seven of the surviving species are endangered.

A look across Hawaii's varied islands, discovering how they were made, and how its wildlife thrives. The most remote island chain on Earth, its tropical shores are hard to reach. However, for the hardy creatures that have made it there, such as the waterfall-climbing fish, carnivorous caterpillar and Laysan albatross, a land of opportunity awaits. From newly formed lava fields, to lush jungles, and vibrant coral reefs, these diverse and beautiful islands have it all. As this documentary reveals, its people are looking to the future and attempting to protect and foster its flora and fauna.
