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.

Meet the big birds, a feathered family who have never flown a day in their lives! From ostriches to kiwis, these bizarre birds appear to be nature's greatest novelty act. How they came to be and how they continue to survive is a fascinating tale that has long captivated Sir David Attenborough. It is a story of dedicated dads, enormous eggs and a serious need for speed. And far from being the court jesters of the animal world, these flightless curiosities once nearly ruled the land.

The team set off beneath the waves to explore this spectacular archipelago. It is an exciting opportunity for the team to delve into a world that still largely remains a mystery to science. Venturing down in the Nadir, a specially equipped deep sea submersible, Liz goes in search of an elusive ocean giant, the mola, or sunfish, to understand more about its little-known behaviour in the deep. On the way back to the Alucia, Liz checks in on a playful sea lion population to see how they have been affected by a recent extreme weather event, El Nino. Back on board the Alucia, the team sets sail north for the most remote and inhospitable islands in the Galapagos - Wolf and Darwin. Here, Liz joins the team tagging and tracking hammerhead sharks that school at this location in huge numbers as they try to unlock the secrets of this stunning behaviour. But nothing can prepare the Alucia crew for the power of the ocean in this isolated marine wonderland.

David Schwimmer explores an underground world of monsters and aliens. The largest gathering of the largest fish on the planet--over four hundred whale sharks--assembles in the same small patch of ocean just off Mexico’s Yucatan Peninsula. Why are they here? Mysterious Planet embarks on an epic journey to find out: from the clear blue waters of the Caribbean, into the largest network of flooded caves on Earth, spiritual underworld of a lost civilization, home to monsters and alien life forms ,where a meteorite the size of Manhattan is hurtling towards planet Earth, on course to kickstart the evolution of a whole new line of ocean giants.
