Visits the world's deepest valley: the Kali Gandaki river in the Himalayas. Its temperatures range from those of the tropics in its lower reaches to that of the poles higher up. It therefore shows how creatures become adapted to living in certain environments.

Describes the inhospitable habitats of snow and ice. Mount Rainier in America is an example of such a place: there is no vegetation, therefore no herbivores and thus no carnivores. However, beneath its frosty surface, algae grow and some insects, such as ladybirds visit the slopes. Africa’s mountains are permanently snow-covered, and beneath peaks such as Kilimanjaro and Mount Kenya, there are communities of plants and animals.

Begins in northern Norway, 500 kilometres north of the Arctic Circle. Here, there is only just enough light for the pine trees to survive, but it is extremely cold during the winter. Pine cone seeds provide one of the few foods available at this time of year, and large herbivores such as the moose must also rely on their fat reserves.

Ascends a kapok in the South American tropical rainforest to observe "the greatest proliferation of life that you can find anywhere on the surface of the Earth. There are two main causes for this: warmth and wetness. As this climate is constant, there are no seasons, so trees vary greatly in their flowering cycles.

Explores the grasses which are present all over the world. Grass sustains huge numbers of creatures the world over, particularly in the African grasslands, where huge numbers of savannah animals have made their homes.

Starts in the Sahara, where the highest land temperatures have been recorded. Rock paintings depict creatures such as giraffes and antelopes, suggesting that at one point there was enough vegetation to support them.

Starts in NASA's gravity research aircraft to illustrate the effect of weightlessness. There are surprisingly many plants whose seeds are, in effect, lighter than air.

Attenborough describes the course the Amazon, starting high up in the Andes of Peru, whose streams flow into the great river. Young rivers are by nature vigorous and dangerous: they flow fast and form rapids, thick with mud and sediment.
1984 • Nature
Details coastal environments and the effect of tides, of which the highest can be found in the Bay of Fundy in North America. In places, erosion is causing the land to retreat, while in others — such as the tropics — the expansion of mangroves causes it to advance.

Investigates remote islands and their inhabitants. Some islands are tips of volcanoes; others are coral atolls. Those that colonise them transform into new species with comparative speed.

Attenborough goes underwater to observe the ocean's life forms and comment on them at first hand.

Dolphins have been a source of curiosity to humans and have appeared in our stories and myths for thousands of years. What is the link between our two species? Why do we seem to be so interested and curious about each other?

This episode is a pioneering exploration of the latest discoveries concerning the Amazon - by far the greatest river on Earth. It is the river of superlatives, flowing more than 4,000 miles from the Andes to the Atlantic. Its 1,100 tributaries drain the greatest river basin on the planet and along its incredible journey it collects and transports one-fifth of the world's fresh water. Due to its enormous size, it still hides secrets.

Jungles comprise the most diverse habitats on Earth in which only the most resilient species triumph; the fiercest jungle species include jaguars, caimans, gibbons, orangutans, spectral tarsiers, hummingbirds, and parasites.

Discover the evolutionary secrets of some of the world’s most majestic creatures. From voracious crocodiles and acrobatic birds to stupendous whales and majestic elephants, WHEN WHALES WALKED follows top scientists on a global adventure as they follow clues from the fossil record and change what we thought we knew about the evolution of iconic beasts.

It is high summer in the Polar Regions, and the sun never sets. Vast hordes of summer visitors cram a lifetime of drama into one long, magical day; they must feed, fight and rear their young in this brief window of plenty. Summer is a tough time for the polar bear family, as their ice world melts away and the cubs take their first swimming lesson. Some bears save energy by dozing on icy sun beds, while others go egg-collecting in an Arctic tern colony, braving bombardment by sharp beaks. There are even bigger battles on the tundra; a herd of musk oxen gallop to the rescue as a calf is caught in a life and death struggle with a pair of Arctic wolves. But summer also brings surprises, as a huge colony of 400,000 king penguins cope with an unlikely problem - heat. The adults go surfing, while the woolly-coated chicks take a cooling mud bath. Nearby, a bull fur seal is prepared to fight to the death with a rival. Fur flies as the little pups struggle desperately to keep out of the way of the duelling giants. Further south, a minke whale is hunted amongst the ice floes by a family of killer whales. The dramatic chase lasts over 2 hours and has never been filmed before. The killers harry the minke whale, taking it in turns to wear it down. Eventually it succumbs to the relentless battering. Finally, comical adelie penguins waddle back to their half a million strong colony like clockwork toys. The fluffy chicks need constant feeding and protection as piratical skuas patrol the skies. When an unguarded chick is snatched, a dramatic "dogfight" ensues.

Plants' solutions to life's challenges are as ingenious and manipulative as any animal's. Innovative time-lapse photography opens up a parallel world where plants act like fly-paper, or spring-loaded traps, to catch insects. Vines develop suckers and claws to haul themselves into the rainforest canopy. Every peculiar shape proves to have a clever purpose. The dragon's blood tree is like an upturned umbrella to capture mist and shade its roots. The seed of a Bornean tree has wings so aerodynamic they inspired the design of early gliders. The barrel-shaped desert rose is full of water. The heliconia plant even enslaves a humming bird and turns it into an addict for its nectar.
