A six-month research expedition aboard the vessel Luminous Deep has returned with extraordinary findings: 120 new species of bioluminescent organisms living between 2,000 and 5,000 meters below the ocean surface. The discoveries include a jellyfish that emits pulsing blue-green light in complex patterns and a worm colony that glows red to attract prey.
"We thought we had a reasonable picture of deep-sea bioluminescence, but we were barely scratching the surface," said chief scientist Dr. Aiko Tanaka of the Monterey Bay Aquarium Research Institute. Several of the new species produce novel light-emitting proteins that could have medical and industrial applications.
