Creatures of Light
Season 43 Episode 9 | 53m 36sVideo has Audio Description, Closed Captions
Deep in the ocean, animals that flash, sparkle, and glow use light to survive in the dark.
On a summer’s night, there’s nothing more magic than watching the soft glow of fireflies switching on and off. Few other life forms on land can light up the night, but in the dark depths of the oceans, it’s a different story: nearly 90% of all species shine from within. Whether it’s to scare off predators, fish for prey, or lure a mate, the language of light is everywhere in the ocean depths.
