Look around on land, and you can see life everywhere. But it’s a different story down in the deep ocean. There are still plenty of animals around, but deeper than about 200 m (660 feet) there’s no light left to see them. Instead, light comes from the sea creatures themselves. More than 90 percent of them give off faint bluish flashes and glows, called bioluminescence, that seem unearthly to visitors from dry land.
