The last Chinese paddlefish spotted in the wild was in 2003, which means that it may already be extinct. Chinese paddlefish are the world’s largest freshwater fish, reaching lengths of 23 feet. They are said to have been a popular meal for Chinese emperors. However, the construction of a dam in the Yangtze River in the 1980s dramatically changed the habitat and well-being of this species. In fact, even if there are some still alive, scientists fear that their may not be enough of them to properly reproduce themselves.
