Clarias angolensis is an African catfish from the Clariidae family. It lives in fresh waters and can breathe atmospheric air, which helps it survive at low oxygen levels.
Clarias angolensis differs from other catfishes by its special organ for air breathing and venomous spines in the fins. It helps maintain balance in freshwater ecosystems of Africa as a predator and detritus consumer.
Immature form that undergoes metamorphosis before adulthood.
