  • Overexploitation and river dams are the primary causes of a huge decline in freshwater animals weighing over 30kg.
  • Species like river dolphins, beavers, crocodiles, giant turtles and sturgeons are facing extinction around the world.
  • From 1970 to 2012, large fish species have declined the most - by 94%, followed by 72% of reptiles.
  • Targeted conservation actions in the USA, Asia, and Europe have successfully been repopulating local areas with different species.
  • However, they are still less studied, and receive less conservation attention than animals on land or in oceans and seas.
