Key Points:
- Researchers from NOAA discovered a mysterious "golden orb" over two miles underwater in the Gulf of Alaska in 2023, which was later sent to the Smithsonian National Museum of Natural History for analysis.
- The orb was identified as a fibrous material covered with stinging cells called spirocysts, characteristic of cnidarians, a group of aquatic invertebrates including anemones and corals.
- Whole-genome sequencing revealed the orb was genetically almost identical to Relicanthus daphneae and was part of the base of a giant sea anemone, typically hidden beneath the organism.
- Scientists remain uncertain about the fate of the anemone's upper portion, suggesting it may have died or relocated, while the full anemone can reach up to three feet across with tentacles up to six feet long.
- NOAA highlighted that advanced DNA sequencing techniques are crucial in solving deep-sea mysteries, enhancing understanding of ocean ecosystems and their potential benefits for economic growth and national security.
