Golden orb off Alaska traced to secretions from a deep-sea anemone-like creature

A long-standing mystery about a shiny golden orb found on Alaska’s seafloor is solved: it’s not an egg or sponge but secretions from Relicanthus daphneae, a deep-sea anemone‑like animal. Microscopy revealed the tissue is a cuticle the creature uses to cement itself to rock, and DNA analysis confirmed the presence of the anemone’s tissue and associated microbes. The findings, posted on bioRxiv, highlight how combining genetic data with physical samples helps identify little‑known deep-sea life.

Deep-Sea Mystery Solved: Golden Orb in Alaska Is Sea Anemone Remains

Scientists determined that the 4-inch 'golden orb' found about two miles deep off Alaska in 2023 is the dead-cell base of a sea anemone, identified after years of analysis by NOAA, Smithsonian, and partners during the Seascape Alaska mapping program; the orb, which initially puzzled researchers who found it stuck to rock on the seafloor west of Prince of Wales Island, is now in the Smithsonian collection and underscores the program’s role in expanding maps of unmapped Alaska waters and informing continental-shelf claims, with DNA sequencing and other techniques helping solve the mystery.

Deep-Sea Gold: Orb Turned Out to Be Anemone Tissue

A glowing four-inch orb found on the Gulf of Alaska seafloor during NOAA’s 2023 Seascape Alaska expedition was identified through later genetic testing as a piece of tissue from Relicanthus daphneae, a rare deep-sea giant sea anemone. The discovery concluded that the orb wasn’t an egg or new species but dead cells at the base of the anemone, underscoring the deep ocean’s ongoing mysteries and the subtle process of tissue shedding that can leave behind such glowing relics.

Golden Orb Mystery Solved: Remnant of a Giant Deep-Sea Anemone Identified

Scientists have solved the two-year mystery of the Gulf of Alaska’s “golden orb,” identifying it as a remnant of the base of the giant deep-sea anemone Relicanthus daphneae. Using morphological analysis and whole-genome sequencing (since initial DNA barcoding was inconclusive), researchers confirmed animal DNA matching Relicanthus daphneae and linked the orb to the rock-attached base of the creature. The specimen has been accessioned into the Smithsonian NMNH collection, illustrating how advanced genomic methods help unveil deep-sea mysteries.
