Pic o’ The Week: Bioluminescent anemone lights up the oceans’ watery depths

NOAA Ocean Explorer: Bioluminescence and Vision on the Deep Seafloor 2015

In the watery nooks and crannies of the oceans, in the deepest, darkest trenches and even in the shallower water, bioluminescence lights up numerous saltwater creatures. Researchers around the world are studying the mechanisms and secrets of bioluminescence in the oceans.And in this holiday season, when the days in the northern hemisphere get short and darkness prevails, we turn to the lights of bioluminescence to add light to our days.

This hormathiid anemone was photographed in light and in darkness by NOAA’s Ocean Explorer.

“On the right is the light emitted from the same animal. The emitted light is blue and comes from a mucous secretion. The animal is not actually red, but we briefly shine a red LED on it to show where it is.”
