Plants are able to communicate with each other in ways we are only now beginning to understand. Some plants can differentiate between roots of their "family" and roots of other kinds of plants when they touch underground. See how plants "talk" to each other and find out what they talk about!

As the Ganges nears the sea, it joins its mightiest tributary the Brahmaputra, creating a vast flood-prone delta. Here the bustling cities of Calcutta and Dhaka meet the wetlands, home to giant lizards and snakes, huge mean-eating crocodiles and forests full of monkeys. This is a story of human life persisting in wildly variable conditions in a domain that is still the preserve of the royal Bengal tiger.
The Caribbean has been shaped by millions of years of unstoppable volcanic forces and ferocious hurricanes, creating a network of 7,000 islands, each one more unique than the next. From islets only a few miles long to landmasses with towering peaks, the habitats of this tropical paradise range from lush rainforests hiding untold species to multi-coloured coral reefs teeming with marine life. The fauna of the Caribbean has had to adapt to an island existence, becoming either generalists or specialists…creatures as old as the dinosaurs nest on its beaches, opportunistic scavengers patrol its skies, iridescent dynamos forage in its forests and wandering ocean leviathans give birth in its warm waters.

As temperatures hit minus 60 food becomes scarce, and animals such as foxes and hares shed their colourful coats to camouflage themselves in the snow. The end of winter heralds one of the world's greatest feeding frenzies as large ocean predators target the millions of fish who have found refuge in the Gulf of Alaska.
While most of the series has focused on conflict, this episode is all about co-operation. The suitably named social spiders spin one enormous, 30m web for the whole colony, a queen bee rules her hive with a strict hierarchy and some green ants show great team spirit to help build a nest together. There are no broken societies here. David Attenborough shifts the focus to bugs that prefer cooperation rather than conflict. They include burrowing cockroaches, the suitably named social spiders - which share a 30-metre web.
