The Chinese paddlefish (Psephurus gladius; simplified Chinese: 白鲟; traditional Chinese: 白鱘; pinyin: báixún: literal translation: "white sturgeon"), also known as the Chinese swordfish, is an extinct species of fish that was formerly native to the Yangtze and Yellow River basins in China. With records of specimens over 3.6 metres (12 ft) and possibly 7 m (23 ft) in length, it was one of the largest species of primarily freshwater fish. It was the only species in the genus Psephurus and one of two recent species of paddlefish (Polyodontidae), the other being the still-living American paddlefish (Polyodon spathula).
