Ocean Creatures and Bioluminescence

Posted by Scripture on Jul. 18, 2009

Tell the world:

A red octopus that drifts through deep waters off the eastern United States shines in a novel way: Its suckers flash on and off. In 1997, Widder brought a live, foot-long specimen from the Gulf of Maine back to a lab. When the researchers turned off the lights, the suckers glowed blue-green, emitting the most light at 470 nanometers, a wavelength that travels well underwater. Its kind of a twinkling effect, Widder says. Such a glimpse into the evolutionary history of a bioluminescent structure holds special interest because of its rarity, notes Widder. Tracing histories of light organs has proved difficult because theres no fossil record for bioluminescence bioluminescence (biolmines`?ns), production of light by living organisms...... ., she laments.
