Etymology: Mormyrus: Greek, mormyros = a fish (Sparus sp) (Ref. 45335).

Issue
Records of Tana and Athi systems are dubious and probably refer to different species; status of North Ewaso Nyiro populations uncertain and needs further study (Ref. 52331).

背面の脊椎 (合計) : 0; 背鰭 (合計) : 55 - 75; 肛門の骨: 0; 臀鰭: 17 - 22. Diagnosis: snout long, about equal to the post-ocular length of the head (Ref. 28714), produced into a stout trunk whose thickness and angle to the face are variable (Ref. 34290). Dorsal fin very long, more than twice the anal fin length, with less than 75 rays, its origin above or slightly in front of the insertion of the pelvic fins (Ref. 4903, 28714).

生物学     用語集 (例 epibenthic)

Solitary, nocturnal species (Ref. 28714). In Lake Victoria in both coastal and offshore waters (Ref. 4903). May spawn in the main lake, perhaps in deep water over rocks (Ref. 52083). In Lake Kyoga in open water rather than weedy areas (Ref. 55624). Bottom feeder; small fishes eat lithophilic insects; adults almost exclusively insectivorous; chironomids dominate in the diet (Ref. 12526). Oviparous (Ref. 205).
