Chitala hypselonotus is a freshwater fish with a long knife-shaped body and a high dorsal hump. It inhabits rivers and swamps of Southeast Asia, can breathe atmospheric air, and hunts at night.
Chitala hypselonotus differs from related species by its high dorsal hump. It is important for nature as a predator that controls the population of small animals in tropical rivers and swamps.
Immature form that undergoes metamorphosis before adulthood.
