Planet Earth II

From adorable pygmy sloths to huge living dragons, islands offer a refuge for the planet's strangest creatures. But life on these isolated lands is full of unexpected challenges. 2006 BBC

The great mountain ranges maybe some of the planet's most spectacular landscapes but they are unforgiving places to live in. Only few pioneering animals have what it takes to endure at extreme altitude. Mountain animals are amongst the most elusive in the world, yet this film provides an intimate glimpse into their secretive lives. Witness the moment four snow leopards come together when a mother and cub become trapped between two rival males. Watch Grizzly bears pole dance against trees to rub off their winter fur and soar with a Golden eagle as it hunts amongst Europe's snow-capped peaks.

Jungles provide the richest habitats on the planet - mysterious worlds of high drama where extraordinary animals attempt to survive in the most competitive place on earth. Flooded forests are home to caiman-hunting jaguars and strange dolphins that swim amongst the tree tops, while in the dense underworld, ninja frogs fight off wasps and flying dragons soar between trees. Acrobatic indri leap through the forests of Madagascar, while the jungle night conceals strange fungi and glow-in-the-dark creatures never filmed before. 2006 BBC

The world's deserts are lands of extremes that force animals to come up with ingenious ways to cope with the hostile conditions and give rise to the most incredible survival stories on Earth. A pride of desert lions are so hungry they risk hunting on a giraffe several times their size, whilst male sand grouse fly 120 miles each day to the nearest waterhole and dice with death to collect water for their chicks. Filmed for the first time, a tiny bat takes on one of the world's deadliest scorpions just to get a meal and in Madagascar a locust swarm of biblical proportion is captured like never before. 2016 BBC

Grasslands cover one quarter of all land and support the vast gatherings of wildlife, but to survive here animals must endure hostile seasonal changes. From Asia's bizarre looking saiga antelope, to the giant ant-eaters of Brazil, grassland animals have adapted in extraordinary ways to cope with these extremes. In the flooded Okavango, lions take on formidable buffalo in epic battles and on the Savannah, bee-eaters take advantage of elephants to help catch insects. 2006 BBC

Cities are the fastest-growing habitat on Earth but, for animals, life in the manmade world is not easy. Some are surprisingly successful - Leopards prowl the streets of Mumbai, Peregrine falcons hunt amongst New York's skyscrapers and 5 million starlings perform spectacular aerial dances over Rome. We welcome some creatures into our cities; In Jodhpur langurs are treated like gods and in Harar locals live in harmony with wild hyenas. Many creatures, however, are struggling to cope in the urban jungle. As the architects of our future will we choose to build cities that are home both for us and for wildlife? 2006 BBC
