The brown snakehead is a large predatory fish from the snakehead family. It inhabits freshwater bodies of Southeast Asia, can breathe atmospheric air, and grows up to one meter in length.
The brown snakehead differs from other snakeheads in its large size and dark body coloration in adults. It is important for nature as the main predator that regulates the population of other fish in tropical waters.
Immature form that undergoes metamorphosis before adulthood.
