Eerie footage shows the rare animal, which has only been filmed around a dozen times, gently pulsing and swirling its way through the water off the coast of Argentina. It was captured on film by scientists at the Schmidt Ocean Institute, whose remotely operated vehicle (ROV) was on its descent to explore the Colorado-Rawson submarine canyon wall. At 253 metres (830 feet) down, they came across the enormous ghostly jellyfish, which was first discovered in 1899.
