E/V Nautilus , an underwater exploration organization, was using a Hercules remotely-operated vehicle to catch a crab when they stumbled upon this guy: The frilled tentacles of the Halitrephes maasi jelly came into view at 1225m in the Revillagigedo Archipelago off Baja California, Mexico. Radial canals that move nutrients through the jelly’s bell form a starburst pattern that reflects the lights of ROV Hercules with bright splashes of yellow and pink–but without our lights this gelatinous beauty drifts unseen in the dark. If the crab was smart, he’d have enlisted the help of the jellyfish to avoid capture. “Goddammit, that Hercules thing is coming back around…hey Halitrephes! Do a brother a solid, swim around in front of that thing to distract it while I ghost these motherf*ckers.”
