Baiji river dolphin: Extinct in 2007

The last documented sighting of this freshwater dolphin was in China in 2002. Though it’s currently listed as critically endangered, a 2006 expedition to locate the species failed to find even 1 individual. Expedition researchers concluded that the baiji is now “functionally extinct.”

The population started declining rapidly when China started utilizing the rivers for fishing, transportation, and hydroelectricity.
