The group opposes efforts to mine the seabed and other extractive activities in areas beyond national jurisdiction, arguing the deep ocean should remain a protected global commons. The campaign urges governments to support a strong international treaty and moratorium on deep-sea mining.

New research from the Monterey Bay Aquarium Research Institute reveals that swimming sea cucumbers are linked to the ocean carbon cycle in a surprising way. The deep-sea creatures, previously thought of mainly as seafloor dwellers, appear to contribute to how carbon moves through ocean waters, adding a new piece to scientists' understanding of carbon storage and climate processes.

The mola mola, one of the heaviest bony fish in the ocean, has no swim bladder. Instead it relies on a thick, gelatinous hypodermis layer under its skin to manage pressure changes as it dives deep to hunt jellyfish. The fish's unusual biology is being highlighted in an episode of 'The Nature of Things,' hosted by Sarika Cullis-Suzuki and Anthony Morgan, drawing fresh interest in the species.

Researchers have described a roughly 5.3-million-year-old whale necropolis on the deep seafloor of the Diamantina Zone, published in Nature. The site preserves fossil whale remains that supported deep-sea ecosystems over geological time. Scientists say such finds shed light on how whale falls sustain specialized marine life and on ancient ocean conditions in the region.

A live broadcast showing divers in deep ocean waters catching fish as part of a self-described hard challenge is attracting millions of viewers and hundreds of thousands of likes. The stream, presented under the Foody Animal name, ranks among the most-engaged ocean-related content globally, with audiences following the diving and fishing attempts in real time.

Researchers report a roughly 5.3-million-year-old deep-sea whale graveyard in the Diamantina Zone, an abyssal region of the southern Indian Ocean. The site preserves whale remains that have sustained deep-sea ecosystems for millions of years, shedding light on how whale falls shape life on the ocean floor.

US lobsterman Jacob Knowles has drawn a large online audience with footage of fishing for so-called monster creatures at extreme ocean depths, pulling up strange deep-sea species rarely seen by the public. The clips have gathered roughly half a million reactions, with viewers praising the rare glimpse of life from the ocean's darkest zones and debating how the animals survive the crushing pressure.

Researchers have identified a previously unknown shark species in the Indian Ocean, distinguished by its large snout and bioluminescent, glowing body.
