Never before has a film crew had such unrestricted access to the wonders of Saudi Arabia's seas. Desert Seas narrated by Sir David Attenborough tells the story of how the peninsula of Arabia transformed from an ocean millions of years ago to the desert it is today.
This episode continues the study of mammals, and particularly those whose young gestate inside their bodies. Attenborough asks why these have become so varied and tries to discover the common theme that links them. Examples of primitive mammals that are still alive today include the treeshrew, the desman and the star-nosed mole. Insect eaters vary enormously from the aardvark, giant anteater and pangolin to those to which much of this programme is devoted: the bats, of which there are nearly 1,000 different species. These took to flying at night, and its possible that they evolved from treeshrews that jumped from tree to tree, in much the same way as a flying squirrel.
Encounter huge shoals of barracuda in Malaysia, fantastic meadows of coral in the Philippines and strange, miniature creatures inhabiting Indonesian reefs. Plus you’ll have to watch for deadly blue-ringed octopus and much more. Simply sublime!
In this episode, Chris reveals how the world's most spectacular grasslands flourish, despite being short of one essential nutrient - nitrogen. As it turns out, the secret lies with the animals. There are the white rhinos of Kenya that create nitrogen hotspots by trimming and fertilising the grass. They are drawn to these particular points by communal toilets or 'fecal facebooks', where they meet and greet each other. In the whistling acacia grasslands of Kenya, Chris reveals the amazing relationships between termites, geckos, ants, monkeys and giraffes that make these places so rich in wildlife
