Marine invertebrates, the descendants of one billion years of evolutionary history, are the most abundant creatures in the ocean. In the Sea of Cortez, packs of Humboldt squid make night-time raids from the deep to co-operatively hunt sardines. Beneath the permanent Antarctic sea ice of McMurdo Sound, sea urchins, red sea stars and nemertean worms are filmed scavenging on a seal carcass. A fried egg jellyfish hunts amongst a swarm of Aurelia in the open ocean, spearing its prey with harpoon-like tentacles. In the shallows off South Australia, hundreds of thousands of spider crabs gather annually to moult. Many invertebrates have simple nervous systems, but giant cuttlefish have large brains and complex mating habits. Large males use flashing stroboscopic colours and strength to win a mate, whereas smaller rivals rely on deceit: both tactics are successful. A Pacific giant octopus sacrifices her life to tend her single clutch of eggs for six months. As a Pycnopodia starfish feeds on her remains, it comes under attack from a king crab. Coral reefs, which rival rainforests in their diversity, are the largest living structures on Earth and are created by coral polyps. Porcelain crabs, boxer crabs and orangutan crabs are shown to illustrate the many specialised ways of catching food on a reef. Marine invertebrates have a lasting legacy on land too – their shells formed the chalk and limestone deposits of Eurasia and the Americas. Life on Location documents the recording of Antarctic sea life and the birth of a reef.
Life is a nature documentary series made by BBC television, first broadcast as part of the BBC's Darwin Season on BBC One and BBC HD from October to December 2009. The series takes a global view of the specialised strategies and extreme behaviour that living things have developed in order to survive; what Charles Darwin termed "the struggle for existence". Four years in the making, the series was shot entirely in high definition.
The UK broadcast of Life consists of ten 50-minute episodes. The opening programme gives a general introduction to the series, a second looks at plants, and the remainder are dedicated to the major animal groups. They aim to show common features that have contributed to the success of each group, and to document intimate and dramatic moments in the lives of selected species chosen for their charisma or their extraordinary behaviour. A ten-minute making-of feature Life on Location aired at the end of each episode, taking the total running time to 60 minutes.
Life is produced by the BBC Natural History Unit in association with the Discovery Channel, Skai TV and the Open University. The original script, used in the British and Canadian versions of the series, was written and narrated by David Attenborough. Source: Wikipedia
