David Attenborough's Living Lights

On Earth, countless creatures create their own light thanks to a natural phenomenon called bioluminescence. This effect is as fascinating as it is hardly understood - even experts are only beginning to understand the origin, the meaning and the consequences of these living lights on our planet. This film reveals a weird world - on land and in the oceans. As viewers will see, bioluminescence often is a special way of communicating in an otherwise dark or even pitch black environment.
