After years of speculation, researchers confirm the golden orb is part of a giant sea anemone discovered in the Gulf of Alaska.

In 2023, a team of scientists aboard the NOAA Ship Okeanos Explorer made a puzzling discovery two miles beneath the waves of the Gulf of Alaska. As they operated a remotely controlled underwater vehicle, they encountered a shimmering, golden orb-like object clinging to a rock. This peculiar find, which sparked wild theories ranging from alien eggs to unknown species, has finally been identified after extensive research.
The core question surrounding this golden orb was simple yet intriguing: What exactly is it? Initially, scientists had no clear idea, leading to a flurry of speculation. Was it an egg case? A dead sponge? Or perhaps something entirely new to science? The orb was found at a depth of approximately 3,250 meters (over two miles) and measured about 10 centimeters across, with a small hole on its surface.
The golden orb was first discovered during NOAA's Seascape Alaska 5 expedition on August 30, 2023. At that time, researchers were exploring the ocean floor when they spotted the strange, mound-shaped mass. It was stuck to a rock, and its unusual appearance quickly captured the attention of scientists and the public alike. Following its collection, the orb was sent to the Smithsonian National Museum of Natural History for detailed examination.
Dr. Allen Collins, director of NOAA Fisheries' National Systematics Laboratory, expressed the initial confusion among scientists. "I suspected that our routine processes would clarify the mystery," he explained. "But this turned into a special case that required focused efforts and expertise of several different individuals. This was a complex mystery that required morphological, genetic, deep-sea, and bioinformatics expertise to solve." The identification process turned out to be far from straightforward.
After rigorous testing, researchers determined that the golden orb is not an alien artifact or an egg but rather a biological remnant from a giant deep-sea anemone known as Relicanthas daphneae. This species, which can grow up to three feet across with tentacles reaching lengths of six feet, is rarely seen due to its deep-sea habitat. The orb itself is part of the organism's base, which anchors it to the ocean floor.
Initial examinations revealed that the orb lacked recognizable animal features. Instead, it was composed of fibrous material packed with stinging cells called spirocysts, which are characteristic of cnidarians—a group that includes corals and anemones. According to Collins, the orb's unique structure and composition required a multidisciplinary approach for identification. "This was a complex mystery that required morphological, genetic, deep-sea, and bioinformatics expertise to solve," he reiterated.
The investigation into the golden orb involved multiple stages. Initially, scientists performed DNA barcoding, but results were inconclusive due to contamination from other microscopic organisms. It wasn't until whole-genome sequencing was employed that researchers could confirm the orb's identity. This advanced technique revealed that the orb was genetically almost identical to the Relicanthas daphneae reference genome.
"The orb had once been part of the base of a giant sea anemone," NOAA explained in a video detailing the research process. The anemone's full body, with its vibrant pink cylindrical shape and lengthy tentacles, is typically hidden beneath the ocean floor, but this remnant was left behind, possibly when the anemone moved or died. Captain William Mowitt, acting director of NOAA Ocean Exploration, emphasized the significance of such discoveries: "So often in deep ocean exploration, we find these captivating mysteries, like the 'golden orb.' With advanced techniques like DNA sequencing, we are able to solve more and more of them."
With the mystery of the golden orb resolved, the focus shifts to the broader implications of this discovery. The deep ocean remains largely unexplored, and many species are still unknown to science. The identification of the orb sheds light on one organism and highlights the vast biodiversity that exists in the ocean's depths. Each new finding contributes to our knowledge of marine life and environmental processes.
NOAA continues to explore uncharted territories, with future missions planned for the Pacific, including dives off the coast of Hawaii. These explorations are not just about satisfying curiosity; they have consequences for economic growth, national security, and environmental sustainability.
The takeaway: The golden orb, once a source of speculation and intrigue, is now identified as a remnant of a giant deep-sea anemone, Relicanthas daphneae. This discovery exemplifies the importance of continued exploration of our oceans, which hold countless secrets waiting to be uncovered.
