Researchers Discover A Mysterious, Glowing Jellyfish.

Scientists on the NOAA research vessel Okeanos Explorer sent their robotic exploration vessel on a dive on April 24, 2016. It was the fourth dive in a series being conducted as the researchers explore the Mariana Trench in the Pacific Ocean.

During that dive, the robot’s camera caught a glimpse of this gorgeous, glowing jellyfish moving gracefully through the water. The jellyfish was spotted at a depth of about 12,139 feet (3,700 meters).

The jellyfish is a hydromedusa, part of the genus Crossota. And it’s a species that the researchers think hasn’t yet seen before. Check out video of the jellyfish here:
