Short description Morphology | Morphometrics

Diagnosis: eye <60% of interorbital space; massive profile specially on anterior part (Ref. 2880, 81279). Three scale rows between lateral line and scaly process at pelvic-fin bases; rakers of first gill arch poorly developed; snout-dorsal fin length/snout-ventral fins length different from one; adipose fin grey or black (Ref. 81279). Inferior lobe of caudal and anterior end of anal fin red-orange (Ref. 2880).

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Africa: Occurs only in Sudano-Sahalian basins (Ref. 2880, 81279): Nile, Chad, Niger/Bénoué, Volta, Senegal and Gambia (Ref. 2880, 5331).

Biology     Glossary (e.g. epibenthic)

Occurs in open water habitats. Piscivorous but may also eat Caridina and insects (Ref. 28714). Affinities: easily distinguished from two other species in West Africa from number of scale-rows below lateral line (3 instead of 2).
