Researchers have discovered 24 previously unknown species of deep-sea amphipods in the Clarion-Clipperton Zone of the central Pacific Ocean, including an entirely new superfamily. The findings, detailed in a ZooKeys special issue published on March 24, highlight previously unknown branches of life in one of Earth's least explored ecosystems. The work advances efforts to catalog biodiversity amid growing interest in deep-sea mining.
