Cats are said to hate water, crave warmth and only eat meat. But in episode three, Super Cats, viewers are introduced to the wild cats that break all the feline rules. From jaguars with sub-aqua skills to tigers that can survive temperatures of minus forty, the programme reveals how cats have developed super powers to survive in the most unlikely landscapes. As well as the iconic big cats, in this final episode viewers get a glimpse into the lives of the most rare and strange cats of all – including a real-life Garfield recently discovered living high in the Himalayas. It’s revealed how the cats’ ability to adapt to extremes has made them some of the most successful predators on the planet.

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.

In Palau, the local economy relies on ecotourism that's sustained by strong legal support. Shark hunting is banned, giant manta rays are protected by law, and tireless efforts are made to combat the acidification an ocean ecosystem housing coral reefs. But can ambitious conservation keep pace with the scale of man-made devastation?
