Giant phantom jellyfish filmed in Argentina's deep sea

Argentina’s scientists aboard Schmidt Ocean Institute's vessel had documented a rare phantom jellyfish also known as Stygiomedusa gigantea from a new deep‑sea expedition. The phantom jellyfish became one of the expedition’s standout sightings as its long arms drifted through the deep.

The expedition brought together researchers from the University of Buenos Aires and CONICET, Argentina’s national science agency. “Besides rare jellyfish, all the biodiversity, ecosystem functions, and connectivity unfolding together was incredible. They opened a window into country’s biodiversity only to find there are so many more windows left to be opened.” said the expedition’s chief scientist.
