30-200 eggs are spawned evey 5-8 days. Male builds nest and tends eggs and larvae. Eggs hatch after 4 days and feed after 12 days.

Maximum longevity: 29 years (wild) Observations: There are unverified reports that these animals live up to 29 years in the wild (http://www.demogr.mpg.de/longevityrecords), though this could be due to confusion with earlier reports of a captive specimen living up to 28 years (Philip Altman and Dorothy Dittmer 1962).

Occupies floodplain pools in Sudd. Feeds on mud, vegetable debris and small invertebrates (Ref. 28714). Affinities: only to P. adspersus, morphologically similar; distinguished through scales on caudal peduncle, dorsal and anal fin rays and body coloration. Generates electric organ discharge (EOD) of short duration (0.08 ms) that seems to correlate with aggregative behavior of the species (Ref. 10460; 10601). During the breeding season, males build nests and while patrolling their territory sporadically emit EODs at a mean rate of 18 Hz. Participating females, on the other hand, discharge at a fairly regular rate (8-11 Hz) and this has been shown to play a role in sex recognition during courtship and spawning. Male and female EOD waveforms also differ in the amplitude ratio of the first and third phase (Ref. 10764). Also produce natural sounds ('grunts', 'moans', 'growl', etc.) at different phases of courtship, nesting and territorial defense (Ref. 10832). A fractional spawner; females able to spawn up to 26 times in the course of one reproductive cycle, laying about 125 eggs per spawning episode. Larval electric organ situated in the deep lateral musculature; that of adults in the caudal peduncle (Ref. 10605).

Africa: Gambia, middle Niger, Volta and Chad basins, coastal rivers of Côte d'Ivoire (Sassandra, Bandama, Mé); also including the Nile. Also known from the Bénoué and Senegal Rivers (Ref. 2915). Subspecies Pollimyrus isidori fasciaticeps and Pollimyrus isidori osborni are restricted to the Congo river basin (Ref. 3203).
