|Etymology||According to Cuvier, Synodontis is an "ancient name for an undetermined fish from the Nile".

|Identification||All species in the genus Synodontis have a hardened head cap that has attached a process (humeral process) which is situated behind the gill opening and pointed towards the posterior. The dorsal fin and pectoral fins have a hardened first ray which is serrated. Caudal fin is always forked. There is one pair of maxillary barbels, sometimes having membranes and occasionally branched. The two pairs of mandibular barbels are often branched and can have nodes attached. The cone-shaped teeth in the upper jaw are short. S-shaped and movable in the lower jaw. These fish produce audible sounds when disturbed rubbing the base of the pectoral spine against the pectoral girdle.
At least 1/3 to 1/2 of all fins have a snow white edging. Long white barbles. Inky sheen to brownish body which bears a spotted pattern in younger fish. The contrast of this spotting diminishes with age.
|Sexing||Both sexes have identical colouration. Females grow slightly larger and tend to be plumper than males. Males have a 4-5 mm genital papilla near the anus.|
