Scientists Solve Mystery of a Deep-Sea Golden Orb

Why It Matters

Identifying the golden orb as a potential new deep‑sea life form could reshape vent ecosystem models and spark biotech interest in its unique biomaterials.

Key Takeaways

• Researchers examined golden orb's layered structure using tactile probes.
• Sample proved soft, delicate, with thin dermal outer layer.
• Observations suggest the orb may be a gelatinous egg case.
• Multi‑layered texture indicates possible biological origin, not mineral.
• Findings could reshape understanding of deep‑sea organism adaptations.

Summary

The video captures a team of marine scientists handling a newly recovered deep‑sea golden orb, a mysterious object retrieved from a hydrothermal vent region. The researchers aim to determine its composition and biological significance.

Using gentle probing, they note the orb’s soft, delicate feel, a thin dermal outer layer, and a smoother top covering a more textured interior. The layered architecture suggests a gelatinous structure rather than a mineral formation, hinting at an organic origin.

One scientist remarks, “It looks like an egg case,” while another observes, “The softer thermal air indicates a living membrane.” The dialogue underscores the cautious approach, fearing the specimen could disintegrate if mishandled.

If confirmed as a novel deep‑sea organism or reproductive capsule, the discovery could expand knowledge of extreme‑environment adaptations and inform future bioprospecting efforts for unique biomaterials.

Original Description

In August 2023, scientists discovered something utterly bizarre in the deep ocean off the coast of Alaska: a golden orb. They found this strange object during an expedition of the NOAA ship Okeanos Explorer using remote-controlled submersibles to explore a seamount in the Gulf of Alaska, more than two miles beneath the surface. The orb was so strange that the scientists had no idea what it was beyond that it seemed to be at least biological in origin.

“This was a complex mystery that required morphological, genetic, deep-sea and bioinformatics expertise to solve,” said Allen Collins, director of NOAA Fisheries’ National Systematics Laboratory, in a statement.

Ultimately, whole-genome sequencing revealed that the orb shared lots of genetic material with deep-sea anemones. Sequencing its and the other specimen’s mitochondrial genomes revealed that they were almost identical to a species of anemone called Relicanthus daphneae. These anemones live on the ocean floor, usually near thermal vents, and have pinkish or pale purple tentacles that stretch as long as seven feet. The scientists now know the orb was, in fact, the remains of the base of one of these anemones.
