In the abyssal depths of the ocean exists an alien world. Over millions of years of evolution, the creatures which inhabit this dark, hostile environment have developed an ingenious strategy to survive: bioluminescence, the production of light from living organisms. This short film explores how creatures on land and in the sea use bioluminescence to their advantage and will also reveal how scientists in Wales and around the world are harnessing the power of bioluminescence to tackle important issues, from pollution to understanding and curing diseases.
The film was first showcased at the National Eisteddfod of Wales, 2018 in Cardiff Bay as part of the 'Living Light' exhibition by researchers at Cardiff University. Subtitles are translated from welsh.
