Glowing jelly beans in the sea

Need a break on Friday afternoon? We recommend the pyrosomes, giant transparent organisms that shine “like white hot cylinders” in the ocean, in the words of 19th century biologist Thomas Huxley. Like corals, pyrosomes consist of thousands of tiny bodies, called zooids, that clone themselves into 12-meter-long tubes. When disturbed, a pyrosome emits a sustained bright glow to confuse and deter predators such as sea turtles, sparking other pyrosomes to light up in a chain reaction. Watch them do their thing in this hypnotic video by The New York Times.
