The Amur catfish is a large scaleless freshwater fish with four long whiskers on its head. It inhabits rivers and lakes of East Asia and feeds mainly on other fish.
The Amur catfish differs from other catfish with its very long whiskers and living only in the fresh water of East Asia. It is important for nature because it regulates the number of small fish and serves as food for large predators.
Immature form that undergoes metamorphosis before adulthood.
