Channa marulius is a large predatory freshwater fish from the snakehead family. It lives in rivers and lakes of South Asia, can breathe air and crawl between water bodies.
Channa marulius differs from other snakeheads by its large size and bright eye-spot on the tail. It is important for nature as a predator that regulates the population of other animals in water bodies.
