Scientists Identify Golden Orb as Sea Anemone Skin in Gulf of Alaska

Whole-genome sequencing showed the orb was tissue from Relicanthus daphneae, a deep-sea anemone with tentacles that can reach 6 feet.

  • On Wednesday, National Oceanic and Atmospheric Administration scientists identified a mysterious 'golden orb' discovered in 2023 as the base of a giant sea anemone, Relicanthus daphneae, solving a deep-sea mystery.
  • Researchers discovered the shiny object during the 2023 Seascape Alaska 5 expedition, spotting the roughly 4-inch mass stuck to a rock around 3,250 meters below the Gulf of Alaska's surface.
  • Whole-Genome sequencing confirmed the tissue was 'genetically almost identical' to a Relicanthus daphneae specimen from 2021, after initial DNA testing proved inconclusive due to potential contamination.
  • The orb consists of 'fibrous material' of anemone skin that 'seems to have been left behind,' NOAA officials said, though scientists remain uncertain whether the animal died or relocated.
  • 'So often in deep ocean exploration, we find these captivating mysteries,' said NOAA Ocean Exploration acting director William Mowitt, emphasizing how advanced DNA techniques unlock secrets of the deep.

Two and a half years ago, researchers on the seabed off Alaska discovered a mysterious, gold-shining, round object that no one knew what it was. Now the riddle of the "golden sphere" (see video above) could be solved by science. US marine researchers had discovered and recovered the unusual object with a diameter of more than ten centimeters in 2023 using a remote-controlled survey vehicle at a depth of 3300 meters on a rock in the Gulf of Alask…
