What makes glowworms glow?

Clip: Season 4 Episode 15 | 5m

If you were to gaze upon a cave full of New Zealand glow worms, you may think you’re looking at a star-lit night sky. Using a small organ at the end of their bodies, these tiny gnat larvae illuminate surfaces of the caves and ravine walls they call home. In this segment, we meet biochemists on a mission to discover the molecular basis for the glow worm’s bioluminescence.
