Description

The ocellated synodontis is an African catfish of the squeaker family (Mochokidae) from the Congo basin in Central Africa. The species grows to about 21 cm and has a stocky body with barbels, an adipose fin and a conspicuous dark blotch on the flank. It inhabits rivers and roots through the bottom for insect larvae, small invertebrates, molluscs and plant matter. Squeakers owe their name to the creaking sound they make with the pectoral spines. Those sharp pectoral and dorsal spines can give painful puncture wounds, so careful handling is advised. The species is safe to eat.
