Considering eighty percent of the earth’s oceans have yet to be explored, it’s not surprising that their mysterious depths continue to turn up new discoveries. A July 2021 expedition into the Hydrographer Canyon off the New England coast was no exception when a team from the National Oceanic and Atmospheric Administration (NOAA) stumbled upon a striking red jellyfish. Spotted at 2,297 feet, the pulsing creature is presumed part of the genus Poralia, which until now, was comprised of a single species.
Scientists say the unfamiliar marine animal appears to have more tentacles than the Poralia rufescens, meaning that it’s likely an entirely new species yet to be classified. “The jellyfish also seemed to have nematocyst warts on the exumbrella (the upper part or outside of the jellyfish’s bell) that probably function both for defense but also to trap prey. The radial canals of this genus often branch randomly, which is not usual for other related jellyfish,” the NOAA said in a statement.
Using the remote-operated Deep Discoverer, the team spotted the creature in the mesopelagic zone—this area, which spans 656 to 3,281 feet, is also referred to as the twilight zone because it’s the last region sunlight can reach before giving way to total darkness—of the Atlantic Ocean around the Gulf Stream. The vehicle is equipped with 20 LED lights that illuminate the ocean depths and allow for high-definition footage like the rare video shown below.
