Snot Sustains Undersea Life
Marine biologists have figured out one of the secrets of life in the deep sea beds of Monterey Bay. Until now, it was unclear how anything could live down there. No sunlight, no photosynthesis, no photosynthesis no plants, no plants, no food for animals.
It turns out we can thank tadpole-like creatures called "giant larvaceans" for secreting huge balls of mucus. The lavaceans live inside these mucus balls until they get too clogged up and gross. At this point, the larvaceans discard their old homes and make new ones. The old dirty mucus balls sink like bombs of carbon and provide food for deep sea animals.
