Key identification features
- Elongated, scaleless, eel-like body with smooth, slippery skin
- Long dorsal and anal fins that run for most of the body length, giving a continuous fin profile
- Broad, flattened head with a pointed occipital process at the back of the skull
- Four pairs of barbels around the mouth, used to sense food in murky water
- Dark gray to olive-brown mottled coloring, with a single sharp, serrated spine on each pectoral fin
- Rounded tail fin and a stocky, muscular body
Common look-alikes
- Other Clarias catfish species: very similar body plan; the pointed occipital process and barbel proportions help separate this species from close relatives
- Channel catfish: has a much shorter dorsal fin that does not run the length of the body, and a forked rather than rounded tail
Where you'll see one
African sharptooth catfish are found across rivers, lakes, swamps, and floodplains throughout Africa and parts of the Middle East, tolerating low-oxygen water thanks to an air-breathing accessory organ, and have become established outside their native range in some regions.
