An ethereal blue glimmer just below the waterline has lured scientists like wisps from folklore to three new glowing species of marine bristle worm (polychaetes).
This color of light has a relatively short wavelength, so it is absorbed less quickly by water than other colors and therefore travels farther underwater. That's why this kind of bioluminescence is usually associated with creatures of the deep. The color of these worms' glow is unusual, given their coastal habitats.
Japan Underwater Films Corporation helped record the action. In the sea, researchers found the bubbles from the SCUBA gear could set off the worm's hypnotic light show. They saw similar results in the lab by nudging the worms' tentacles with tweezers.The pattern in which these glimmering lights flickered was near identical in all three species.
