Watch David Attenborough's Great Barrier Reef live

The team behind the triple-Emmy Award-winning series "David Attenborough's First Life" return with another wildlife spectacular hosted by the nature veteran. The focus of the series is the Great Barrier Reef, which Attenborough became enthralled with after filming there back in 1957. Revisiting the area once again with the latest camera technology allows the filming crew to capture even the smallest life-forms. Through the use of satellite scanning, the expanse of the world's largest living organism is viewed in all its glory.
