Short description Morfología | Morfometría

Espinas dorsales (total): 0; Radios blandos dorsales (total): 28-37; Espinas anales 0; Radios blandos anales: 23 - 27; Vértebra: 39 - 41. Diagnosis: Dorsal fin up to 1.5 times in length of anal fin; origin of dorsal fin in advance of anal fin (Ref. 52193). Snout rounded, in front of mouth; eye well above mouth; chin with fleshy bulge (Ref. 4967). For distinguishing between specimens of Cyphomyrus discorhynchus en C. cubangoensis, the most useful anatomical characters are: longer dorsal fin length, longer anal fin length, higher number of dorsal fin rays and anal fin rays, and a higher caudal peduncle depth and caudal peduncle length ratio in C. discorhynchus than in C. cubangoensis (Ref. 119538).

Biología     Glosario (por ej. epibenthic)

Nocturnal shoaling species; favors large river channels with a soft bottom and fringing vegetation (Ref. 7248, 52193). Found mainly in sheltered bays, lagoons and swampy areas; occurs also in typical sandy or rocky rivers (Ref. 13337). Feeds on bottom-living invertebrates (Ref. 52193) and insect larvae at night (Ref. 5595). Known to migrate up tributary rivers of Lake Kariba during rainy season, though it is not yet clear whether this is a breeding migration (Ref. 13337). Breeds during summer rainy season; females carry up to 5,000 eggs (Ref. 7248).
