The brown, dark-spotted body has notably large eyes, three pairs of barbels around the inferior mouth, an adipose fin and stout, serrated spines in the pectoral and dorsal fins that can cause painful puncture wounds. Like many synodontis catfish it can swim upside down to forage at the water surface or the undersides of leaves. The species comes from the Congo basin in Central Africa and lives on soft bottoms of rivers, creeks and lakes. As an omnivore it eats insect larvae, molluscs, crustaceans, growth and detritus. It can make squeaking sounds with its pectoral spines and is popular in the aquarium hobby.
