A quarter of freshwater wildlife is threatened with extinction
An assessment of the extinction risk of freshwater fauna, covering more than 23,000 species, reveals that around 24% of the species studied are at risk of extinction. The analysis, published in Nature, identifies the main threats from pollution, dams, agriculture and invasive species. Decapods - such as freshwater crabs and shrimps - have the highest percentage of threatened species (30 %), followed by freshwater fish (26 %) and odonates - such as dragonflies (16 %).
