Rare Arctic squid sighted in Greenland; Antarctic Blood Falls microbes uncovered

Researchers from the University of Western Australia observed a rare Arctic dwarf squid (Rossia moelleri) in its natural habitat for the first time. The adult female and several egg masses were recorded at about 50 m depth in the Northeast Greenland National Park, where water temperature was around –1.6 °C. The observation was made using a lightweight remotely operated vehicle and was supported by Secret Atlas Micro Cruise Expeditions and Yachts for Science. The find provides new insight into cephalopod life under extreme conditions and offers a baseline for studying climate‑related changes in Arctic marine ecosystems.

In Antarctica, a team led by Angela Zoumplis investigated the iconic Blood Falls at the terminus of the Taylor Glacier. Genetic analysis of 167 samples revealed an active marine microbial community that has survived for millennia, isolated beneath the ice. About 9 % of the eukaryotic organisms share a marine origin, confirming that ancient seawater once flooded the valley before being trapped by glacial advance. The study, published in Nature Geoscience, highlights the resilience of microbial life in extreme environments and adds to understanding of past Antarctic oceanic conditions.
