The mysterious golden orb discovered two miles deep in the Gulf of Alaska has been identified as part of a rare giant deep-sea anemone, according to NOAA and Smithsonian scientists.
Scientists from NOAA and the Smithsonian Institution have successfully identified a peculiar golden orb found deep beneath the Gulf of Alaska. Initially discovered during a 2023 deep-sea expedition, the orb was rumored to be everything from an alien egg to an unidentified species.
After extensive investigation, researchers confirmed that the orb is a remnant of a rarely seen giant deep-sea anemone known as Relicanthus daphneae. Specifically, it is part of the structure that anchors the organism to the ocean floor.
The discovery occurred at a depth of approximately 3,250 meters (over 2 miles) using a remotely operated vehicle. This vehicle encountered the unusual golden structure attached to a rock, which left scientists puzzled. The orb’s mound shape and small opening led to a flurry of questions among researchers.
“Was it an egg case? A dead sponge? Had something crawled into it or out of it?” scientists wondered at the time. The unusual find quickly captured public attention, sparking speculation both online and within the scientific community.
Determining the identity of the orb proved to be a complex task. Dr. Allen Collins, a zoologist and director of NOAA Fisheries, noted that the investigation required the collaboration of multiple experts to solve the mystery.
“This was a complex mystery that required morphological, genetic, deep-sea, and bioinformatics expertise to solve,” Collins explained.
Initially, scientists faced challenges because the orb lacked recognizable animal features. However, closer examination revealed that it was composed of fibrous layers filled with stinging cells, indicating a connection to cnidarians, a group that includes corals and anemones.
Capt. William Mowitt, acting director of NOAA Ocean Exploration, emphasized the importance of continued exploration of the deep ocean. He described the golden orb as just one of many captivating mysteries hidden beneath the waves.
“This is why we keep exploring — to unlock the secrets of the deep and better understand how the ocean and its resources can drive economic growth, strengthen our national security, and sustain our planet,” Mowitt stated.
The identification of the golden orb not only adds to our understanding of deep-sea ecosystems but also highlights the ongoing need for exploration and research in these largely uncharted waters. As scientists continue to uncover the mysteries of the ocean, they pave the way for new discoveries that can have far-reaching implications for science and society.
According to NOAA, the findings underscore the significance of deep-sea research and the potential for discovering new species and understanding marine biodiversity.
