Description

The Chinese paddlefish was one of the largest freshwater fishes in the world, a paddlefish (Polyodontidae) from the Yangtze River system in China. The species could grow to about 3 metres and had a streamlined, scale-poor body with an extraordinarily long, sword-shaped snout full of electric senses, with which it detected prey. As a migratory top predator it hunted fish and crustaceans. Through dams and overfishing it has not been seen since the early part of this century and is considered extinct. To humans it was harmless.
