Scientists Identify 31 New Deep-Sea Species in 2 Weeks Using 3 Advanced Cameras
3 articles · Updated · PetaPixel · Jun 13
Summary
An international team aboard the Falkor documented 31 previously unknown midwater species off Brazil during a two-week South Atlantic expedition, photographing animals usually too fragile to collect.
Three imaging systems on the ROV SuBastian — MBARI’s DeepPIV and EyeRIS plus a Japanese shadowgraph camera — produced non-invasive 3D and silhouette images, cutting confirmation time from decades to days.
The finds included nine jellyfish, seven siphonophores, seven comb jellies, four larvaceans, two giant rhizarians, an amphipod and a fast-moving gossamer worm.
Researchers also reported far greater midwater diversity and abundance than expected in Earth’s largest habitable ecosystem, spotting animals such as glass squid and a pelagic octopus feeding on a bright red jellyfish.
Could our newly found, tadpole-like deep-sea relatives hold the key to understanding our own evolutionary past?
What medical breakthroughs might be hiding in the Earth's largest, and only now explorable, habitat?
With technology unveiling deep-sea life, are we winning the race between discovery and its unseen destruction?
Unveiling Earth’s Hidden Biodiversity: The 2026 Brazilian Deep-Sea Expedition and the Discovery of 2,000+ New Marine Species
Overview
In June 2026, the Falkor (too) expedition off Brazil made a breakthrough by discovering a surprising diversity of deep-sea life. An international team of experts, including Dr. Karen Osborn, found far more midwater organisms than expected, revealing a vibrant ecosystem filled with unique creatures that seemed almost unreal. Among the discoveries were delicate glass squid, a pelagic octopus feeding on a red jellyfish, and tadpole-like larvaceans. These larvaceans build intricate, balloon-like mucus houses, showing just how complex and strange deep-sea life can be. This highlights how much of the ocean’s biodiversity remains unexplored.
