24 new species from the ocean floor: scientists even found “a new branch of life”

Researchers working in the Clarion–Clipperton Zone in the Pacific Ocean have announced the discovery of 24 new amphipod crustacean species previously unknown to science. Among the finds are organisms so unusual that one of them has been placed into an entirely new superfamily, effectively adding another branch to the tree of life. This region has long attracted attention due to its rich deposits of metals on the seabed, but the new study shows that its biological diversity has been seriously underestimated.

The scientists emphasize that the newly discovered species are adapted to extreme conditions: enormous depths, high pressure and a lack of light. DNA analyses revealed that many of these animals diverged from their closest relatives millions of years ago, preserving unique survival strategies. The researchers warn that industrial mining plans in the Clarion–Clipperton Zone could destroy ecosystems that have not yet been described, and they call for strict environmental standards and a cautious approach.​

One of the project’s goals is to build a comprehensive database of deep‑sea species to monitor ecosystem changes as human impact grows. The authors note that such discoveries help refine estimates of how deep‑sea communities contribute to global carbon and nutrient cycles. In the long term, this may influence climate models and international policy on ocean protection.​
