Deep-sea mining could devastate enigmatic mollusks, scientists warn

A new update to the IUCN Red List warns that deep-sea mining could drive more than half of the snail and mollusk species that depend on hydrothermal vents to extinction. The assessment, released on July 18, 2026, highlights the vulnerability of these enigmatic mollusks to the physical destruction and sediment plumes caused by mining operations. The International Union for Conservation of Nature (IUCN), the global authority on species status, conducted the analysis. Deep-sea mining targets polymetallic nodules and other mineral deposits on the ocean floor, often in areas rich in hydrothermal vent ecosystems. These vents host unique, slow-reproducing species found nowhere else. The warning adds to growing scientific and environmental opposition to deep-sea mining, which has not yet begun on a commercial scale but is being explored by several nations and companies.

Global Impact

This story has significant environmental and industry-specific implications. Environmentally, it underscores the fragility of deep-sea ecosystems and the irreversible loss of biodiversity if mining proceeds.
