It is one of the wonders of nature that just about any of us can witness.While a few organisms can produce bioluminescent light outside of the oceans（think fireflies）, most of the bioluminescence going on is in salt water. In fact, the vast majority of bioluminescent organisms evolved in order to provide light in deep sea marine ecosystems—either to light up prey or as a warning against predators（捕食者）—far below sunlight39。s reach into the water column.Humans have been putting natural bioluminescence to work for a while—19th century coal miners would trap fireflies（instead of openflame candles or l
