Alien-Like Jellyfish Discovered Near the Mariana Trench

The National Oceanic and Atmospheric Administration (NOAA) sent its Okeanos Explorer to depths of about 3,700 meters near the Mariana Trench to investigate the so-called “Enigma Seamount”—an area largely unknown to scientists. There, photos were taken of this likely undiscovered jellyfish. From the genus Crossata, the smallish “hydromedusa” is marked by its dome-like body ringed in tentacles.
