New deep-sea octopus species discovered near the Galápagos Islands at extreme depth
Scientists have identified a new species of deep-sea octopus discovered nearly 6,000 feet (about 1,773 meters) beneath the ocean surface near the Galápagos Islands. The tiny organism, about the size of a golf ball, was first observed during a 2015 deep-sea expedition conducted using a remotely operated underwater vehicle exploring the seafloor near an underwater mountain close to Darwin Island. Researchers were surprised when the bright blue octopus appeared on camera moving across the ocean floor, leading to its collection and further study.
After the expedition, multiple deep-sea specimens were examined at the Charles Darwin Research Station, but the unusual octopus stood out immediately due to its distinctive coloration and morphology. Because only one confirmed specimen was available, scientists avoided traditional dissection methods to preserve the rare sample. Instead, they relied on micro-computed tomography (micro-CT) scanning to create detailed 3D models of its internal anatomy, including organs and mouth structures. This non-destructive imaging technique allowed researchers to study key features without damaging the specimen.
The analysis confirmed that the octopus represented a previously undescribed species, later named Microeledone galapagensis. The discovery was formally published in the scientific journal Zootaxa. Experts involved in the study emphasized the importance of advanced imaging tools in modern taxonomy, especially when dealing with rare deep-sea organisms. Researchers also highlighted how little is known about deep ocean ecosystems, noting that vast regions remain unexplored. The discovery underscores both the biodiversity of the Galápagos marine environment and the importance of continued deep-sea exploration to better understand and protect fragile ocean habitats.

The Greenpeace deep-sea livestream is back online!
They're at the Schulz Bank Seamount in the Arctic, which rises from a depth of more than 2,500m at the foot to 600m at the summit.
It's known as a biodiversity hotspot.
Utterly mesmerising.

Deep-Sea Golden Orb Identified as Remains of Rare Anemone

Deep-Sea Golden Orb Identified as Remains of Rare Anemone
A mysterious golden orb discovered on the seafloor of the Gulf of Alaska during a NOAA Ocean Exploration expedition has finally been identified after years of scientific analysis. Initially retrieved because its smooth, shiny surface did not resemble any known marine organism, the object sparked widespread speculation, including theories that it might be an egg, a biofilm, or even an extraterrestrial artifact. Early examinations ruled out non-biological origins after researchers detected spirocytes—specialized cells found only in cnidarians, the animal group that includes jellyfish, corals, and anemones. This finding narrowed the possibilities significantly. Subsequent genetic sequencing provided a breakthrough, revealing a 99.9 percent match with Relicanthus daphneae, a rare and poorly understood deep-sea anemone that lives at depths between 1,600 and 4,000 meters. Despite the strong genetic link, scientists initially struggled to explain how the orb related to the known structure of the species, since it did not match any typical anatomical form. Further investigation, including revisiting earlier specimens and observing live individuals, revealed that Relicanthus daphneae produces a multi-layered golden cuticle at its base. As the anemone moves along the seafloor, it sheds this material, which can remain intact on rocks or sink and form capsule-like shapes. The so-called golden orb was ultimately identified as this detached cuticle, a byproduct of the animal’s locomotion and biology. The discovery not only resolves the mystery of the object but also improves scientific understanding of a species that remains difficult to classify within cnidarians. Researchers note that deep-sea biodiversity is still largely unexplored, with more than 80 percent of the ocean remaining unmapped or unobserved in detail, suggesting many more unknown biological processes may still be awaiting discovery.

The Center for Biological Diversity has submitted a petition
[https://web.archive.org/web/20260512191823/https://biologicaldiversity.org/w/news/press-releases/petition-seeks-us-action-on-chinas-inadequate-shark-finning-prevention-2026-05-12/]
to NOAA [National Oceanic and Atmospheric Administration in the U.S.] Fisheries,
urging the agency to identify and impose sanctions on China for extensive shark
finning conducted by commercial fishing vessels. According to the environmental
group, Chinese-flagged ships have caught and finned thousands of sharks in
offshore waters, yet China has failed to take sufficient measures to stop the
practice. […] The group notes that in 2024, China and Japan blocked an attempt
by the International Commission for the Conservation of Atlantic Tunas to adopt
a fins-naturally-attached policy, despite support from about 80 percent of
member parties. An investigation by the Environmental Justice Foundation
released earlier this year reported widespread shark finning among China’s
distant-water fleet. The nonprofit interviewed 81 fishers from 60
Chinese-flagged vessels and found that 60 percent of those vessels allegedly
engaged in finning sharks and disposing of their bodies. The report also noted
that China’s regulation on controlling shark finning does not apply to squid
vessels operating in the Southeast Pacific. […] In its petition, the Center for
Biological Diversity asserts that China’s distant-water longline fishing fleet
regularly targets sharks and also harvests them as bycatch within regional
fishery management organization convention areas globally. The group claims that
in 2023, Chinese-flagged vessels discarded more than 10,000 blue sharks and
nearly 1,700 shortfin mako sharks in the Western and Central Pacific. […]
