In the second episode; India is a subcontinent surrounded by mountains. We explore the little-known Western Ghats at the edge India's south. Here are Monsoon hills covered in lush forests and tea gardens which shelter some of the greatest biodiversity in the world. But far to the north lies the mighty Himalayas - so vast they drive the climate by capturing the monsoon winds and protect India from the northern chill. It's a unique world full of life.
There are 200 million insects for each of us. They are the most successful animal group ever. Their key is an armoured covering that takes on almost any shape. Darwin's stag beetle fights in the tree tops with huge curved jaws. The camera flies with millions of monarch butterflies which migrate 2000 miles, navigating by the sun. Super slow motion shows a bombardier beetle firing boiling liquid at enemies through a rotating nozzle. A honey bee army stings a raiding bear into submission. Grass cutter ants march like a Roman army, harvesting grass they cannot actually eat. They cultivate a fungus that breaks the grass down for them. Their giant colony is the closest thing in nature to the complexity of a human city.
The undercover cameras reveal how animals often get up to mischief among themselves - and some are downright criminal. A colony of adelie penguins hunker down to avoid a storm, unaware one of them is a thief out to steal the stones that make up their nests, and Spy Tropicbird witnesses an aerial attack by aggressive frigate birds who attempt to steal his fish. A boisterous elephant has a temper tantrum in the mud near the waterhole, chimpanzees have extra-marital affairs and lemurs get high by sniffing toxic millipedes.
In a revelatory look at Svalbard, the most northerly region in the series, Steve Backshall leaves no stone unturned as he unravels the secrets that lie covered in ice for most of each year.
