The discovery of a strange golden object, dubbed the “golden orb,” captured the imagination of scientists and the public alike after it was brought to light during a 2023 NOAA expedition. For over two years, researchers have been painstakingly working to unravel the enigma. The orb, discovered at a staggering depth of 3,250 meters (over 2 miles) in the Gulf of Alaska, was ultimately revealed to be a fragment of a deceased giant deep-sea anemone, *Relicanthus daphneae*. Specifically, it was part of the anemone's base, the anchoring structure that secures the animal to the rugged seafloor.
The initial discovery in 2023 was made by the remotely operated vehicle (ROV) Deep Discoverer, deployed from the NOAA Ship Okeanos Explorer. The team initially puzzled over the rounded, golden object with a small opening, sparking speculation about everything from egg cases to entirely new lifeforms. The object's unusual appearance fueled widespread curiosity and raised questions about potential new species. To investigate further, scientists carefully collected the object with a suction sampler and sent it to the Smithsonian National Museum of Natural History (NMNH) for rigorous study.
The solution to the mystery was a complex, years-long endeavor. Researchers employed an integrative taxonomic approach, combining physical examination with genetic testing. Ultimately, the analysis revealed the object was composed of fibrous layers packed with cnidocytes (stinging cells) – confirming its classification within the cnidarian group, which includes corals and anemones. Further investigation identified the cells as spirocysts, a feature unique to Hexacorallia, finally confirming the object’s origin as part of the *Relicanthus daphneae* anemone.
