Deep below the ocean's surface, scientists last week discovered a glowing jellyfish believed to be an ambush predator. The almost fake-looking jellyfish was spotted on the Enigma Seamount near the Mariana Trench, 2.3 miles underwater. The National Oceanic and Atmospheric Administration (NOAA) research vessel Okeanos Explorer is collecting data from the Marianas Trench Marine National Monument and the Commonwealth of the Northern Mariana Islands, two areas where little is known about the environment, and made the find. Scientists believe the jellyfish, which glows red and yellow, belongs to the genus Crossota.
