There is plenty of food in the Pacific Ocean, but it is the challenge of finding that food that drives all life in the Pacific. In the voracious Pacific we meet a destructive army of mouths, a killer with a hundred mouths and the biggest mouth in the ocean.
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.
