- The Chinese paddlefish (Psephurus gladius) was last recorded by researchers in 2003. Subsequent local surveys failed to spot any individual.
- A new study based on a comprehensive large-scale survey in 2017 and 2018 and statistical analysis of previous records suggest that the species most likely went functionally extinct by 1993 and completely extinct by 2010.
- There’s always the possibility that individuals of a species declared extinct still survive somewhere, but in the case of the Chinese paddlefish that’s highly unlikely, researchers say.
- The factors that contributed to the paddlefish’s extinction, including the construction of a dam that split its population, also threaten other species unique to the Yangtze River basin.
