OLogy: They Glow!

Discover how these deep sea creatures create their own light!

Only the top layer of the ocean gets a lot of sunlight. Many marine animals aren’t in the dark, however, because they make their own light. Some animals, like the Bermuda fireworm, use a process called bioluminescence . Chemicals in the bodies mix together to produce “cold light,” which doesn’t give off any heat. Some bioluminescent animals, like the anglerfish, get their glow from tiny microbes that live inside special light organs in their bodies.
