Marine biologist David Gruber and his team discovered them deep in a canyon off the coast of California. Females (left) and males (right) have distinct twinkling spots and patterns that make it easier for them to see each other in their dark underwater world. Curious why they’re called “swell sharks”? Well, when they’re threatened, they can gulp down water and blow up like an inner tube to twice their original size to avoid getting eaten. To learn more about biofluorescent sea creatures, go to go.ted.com/glowsharks. Happy #sharkweek!  Photo courtesy of David Gruber」8月2日 0時06分 - ted
