Bioluminescence is the Most Common Form of Communication on the Planet

While you go about your day on land, parts of the ocean are lit up with bioluminescent light. Creatures use oxygen, luciferin and liciferase to make cold light. The ocean is twinkling and sparkling from the midnight zone to the surface with living light. This video is from the Need to Know (N2K) series produced by Tree Media
