Scientists Find First “Glowing” Sea Turtle

A new video shows what scientists believe is the first evidence of a reptile exhibiting biofluorescence. That’s the ability to reflect blue light and re-emit it as a different color — in this case, bright green and red. It was during a dive one night in July in the Solomon Islands that marine biologist David Gruber of City University of New York captured footage of the glow of a critically endangered Hawksbill sea turtle. He said it looked like a big spaceship. He followed the rare turtle with his camera system for a while but left it alone as it dove down deep because he “didn’t want to harass it.” Gruber said it’s too early to determine why the turtles fluoresce. — Read it at National Geographic
