Scientists have known that sea pickles have special cells called photosites, located as spots around their bodies, that allow them to glow. But the species is hard to study.David Gruber was on the southeast shores of Brazil when the ocean started glowing. He was testing out a squishy robotic hand that was attached to his submarine with the help of two colleagues when a colony of sea pickles swam by shining in their characteristic blue light.
“This paper begins to uncover some of the mystery behind bioluminescence in chordates,” says biologist Rene Martin, a Ph.D. candidate at the University of Kansas who wasn’t involved in the study. Most of the things we know about bioluminescence in animals come from studying non-chordate creatures like jellyfishes or plankton. Chordates that can glow are hard to study. They are often hidden in the deep ocean and rarely come up to the surface.
that instruct the creatures to start a chemical reaction that stimulates a molecule called luciferin. This molecule releases light when the animal is disturbed.
Wouldn’t that be cool if we had bioluminescent genes?🤔
