Bioluminescence_ Why the Ocean Glows in the Dark

Below a thousand meters, the ocean falls into permanent darkness — and yet, more than three quarters of deep sea creatures have found a way to make their own light. Tonight's episode of Deep Sleep Science drifts slowly through the glowing world of bioluminescence: the anglerfish's deceptive lure, the lanternfish's nightly migration, a dragonfish that sees in a color almost nothing else can, and a jellyfish that lights up like an alarm when danger comes close. Narrated slowly and calmly, with no sound effects, this episode is designed to ease your mind toward sleep while your curiosity drifts gently through one of the ocean's quietest wonders.
