A golden mound-shaped object, measuring around 10 centimeters, sparked speculation after being found more than 3,200 meters deep in Golfo of Alasca. The item has caught the attention of scientists and the public since 2023. Agora to Administração Nacional Oceânica and Atmosférica of Estados Unidos (NOAA) announced the solution to the mystery.
The golden orb was the remnant of the base of a giant deep sea anemone, of the species Relicanthus daphneae. The remotely operated vehicle Deep Discoverer collected the material during the Seascape Alaska expedition. The sample was sent to NOAA’s Laboratório Nacional of Sistemática of Pescas, in Museu Nacional of História Natural of Smithsonian, in Washington.
Bright Objeto intrigued team at the bottom of the ocean
The discovery occurred on August 30, 2023. Deep Discoverer was exploring the region when the vehicle’s lights illuminated the object stuck to a rock. The golden material had a hole on one side and looked like a mound.
The shape and shine generated immediate doubts. Poderia be an egg? A dead sponge? Algo never seen before? The team collected the item with a suction sampler for further analysis. The process followed standard deep-sea collection protocols.
- The orb measured just over 10 cm.
- Estava fixed to rocky substrate.
- Profundidade recorded exceeded 3,250 meters.
- Coleta preserved the integrity of the material for study.
- Envio occurred shortly after the expedition returned.
Análise on Smithsonian lasted more than two years
Cientistas examined the sample with morphological, genetic and bioinformatics methods. The process required collaboration between experts in deep seas and cnidarian systematics. Testes DNA initials were inconclusive.
Sequenciamento complete mitochondrial genome compared the orb with known specimens. The results showed almost identical correspondence with Relicanthus daphneae. Essa anemone lives at extreme depths and is rarely observed.
Allen Collins, zoologist and director of the NOAA laboratory at Smithsonian, followed the work. Ele highlighted the need for concerted efforts to resolve the case. The golden structure corresponded to the cuticle secreted by the anemone to attach itself to the rock.
Espécie Relicanthus daphneae lives in extreme environments
The Relicanthus daphneae anemone belongs to the group of cnidarians. Exemplares of the same species were recorded in other regions, as were Ilhas Marianas in 2016. The animal can detach itself from the base and leave the material behind.
The golden orb consisted of dead cells from the attachment structure. Essa partly helps the organism anchor itself to hard substrates on the sea floor. The golden color results from characteristics of the tissue preserved under high pressure and low light conditions.
Cientistas observed that anemones of this type inhabit abyssal areas. Poucos humans access these environments. The discovery reinforces how much there is still to know about life at great depths.
Coleta and preservation follow international standards
The expedition used the NOAA ship Okeanos Explorer. The Deep Discoverer operated with high-definition cameras and precise manipulators. The collection avoided unnecessary damage to the local ecosystem.
The sample is now part of the Smithsonian invertebrate zoology collection. Esse collection allows future comparisons and studies. Pesquisadores plan to continue analyzes of the species’ distribution.
The case demonstrates the importance of keeping samples for prolonged investigation. Muitos deep-sea organisms only reveal their identity after detailed laboratory examinations.
Oceanic Exploração reveals secrets of the planet
NOAA maintains mapping and collection programs in underexplored areas. Expedições like Seascape Alaska generate data on biodiversity, geology and marine chemistry. Esses efforts contribute to the understanding of the global ocean.
The golden orb attracted public interest soon after the first images were released. Muitos followed the mystery on networks and in media outlets. The scientific solution closed the cycle that began in 2023.
Cientistas emphasize that the bottom of the sea still holds many surprises. Tecnologias remotely operated vehicles allow safe access to these hostile environments. Novas expeditions are expected to follow in the coming years.
Detalhes technicians confirm connection with anemone
The material underwent morphological examinations that identified the characteristic cuticle. Sequenciamento comparative genetics eliminated other hypotheses, such as unknown sponges or eggs. Combining data confirmed the origin.
The Relicanthus daphneae can reach large sizes. Sua attachment base forms flexible structures that remain on the substrate after the animal moves. The orb found represented exactly this portion.
Future Estudos could map genetic variations between populations in different oceans. Knowledge about deep-sea species helps in the conservation of vulnerable habitats.
