The International Union for Conservation of Nature and Natural Resources, or IUCN, has announced the extinction of the Chinese paddlefish, the wild Yangzte Sturgeon.
In its updated Red List of Threatened Species, the organization reviewed that world's remaining 26 sturgeon species are now at risk of extinction.
The reassessment notes sturgeons have been overfished for their meat and caviar for centuries.
Dams affect all sturgeon species migrating to their breeding grounds, while rivers warming due to climate change further disrupts reproduction.
The Chinese paddlefish is one of the world's largest freshwater fish species, with a length of up to seven meters.
It was listed as a first-class state protected animal in China in 1989.
In 1996, it was first declared "critically endangered" by the IUCN.
Some experts say there is no image evidence of the species since 2009.
It was last seen alive in 2003.
