The biological light, or bioluminescence, in the waves is the product of marine microbes called phytoplankton—and now scientists think they know how some of these life-forms create their brilliant blue glow.
Various species of phytoplankton are known to bioluminesce, and their lights can be seen in oceans all around the world, said marine biologist and bioluminescence expert Woodland Hastings of Harvard University. (Also see “Glowing Sea Beasts: Photos Shed Light on Bioluminescence.”)
“I’ve been across the Atlantic and Pacific, and I’ve never seen a spot that wasn’t bioluminescent or a night that [bioluminescence] couldn’t be seen,” Hastings said.
The most common type of marine bioluminescence is generated by phytoplankton known as dinoflagellates. A recent study co-authored by Hastings has for the first time identified a special channel in the dinoflagellate cell membrane that responds to electrical signals—offering a potential mechanism for how the algae create their unique illumination.
