Deep sea explorers just filmed a giant phantom jellyfish off Argentina—and it’s wild. This ghostly, massive jelly has arms over 30 feet long and a bell bigger than a yoga ball. It’s so rare, it’s only been seen about a dozen times on camera. The footage shows it pulsing through the dark, with tiny fish hanging out in its silky arms. Seriously, this thing looks straight out of a sci-fi movie! #Science #DeepSea #Jellyfish
