Study Warns of Severe Extinction Risks for Freshwater Species

New research reveals that nearly a quarter of freshwater species are critically endangered, with pollution, habitat loss, and invasive species as primary threats.

A global study led by the IUCN found that 24% of freshwater species analyzed are at high risk of extinction, including fish, crustaceans, and dragonflies.
Crustaceans, such as crabs and crayfish, are the most threatened group, with 30% of species endangered, followed by 26% of freshwater fish and 16% of dragonflies.
Key threats include pollution (affecting 54% of species), dam construction and water extraction (39%), and land-use changes from agriculture (37%).
Since 1500, 89 freshwater species have been confirmed extinct, with 178 more presumed extinct and 11 surviving only in captivity.
Researchers emphasize the urgent need for conservation efforts, integrating biodiversity protection into water management policies, and addressing data gaps to prevent further losses.
