Africa: freshwater rivers of West Africa (Ref. 188, 2244), in lagoons, lakes, lower and upper courses of rivers from Senegal to Cross River (Ref. 81269), including upper reaches of Niger and lower parts of Benue River (Ref. 188); and lagoons and lower and middle courses of coastal rivers from Cameroon to Democratic Republic of Congo (Ref. 2244, 81631). Reported from the Léfini River (Ref. 88782), but apparently not in upper parts of Congo system (Ref. 188). Also reported from Atlantic Ocean, including beaches at Hann near Dakar in Senegal and near Pointe Noire in Congo Republic (Ref. 188).

Short description Khóa để định loại | Hình thái học | Sinh trắc học

Các tia vây lưng cứng (tổng cộng) : 0; Các vây lưng mềm (tổng cộng) : 13 - 19; Tia cứng vây hậu môn: 0; Tia mềm vây hậu môn: 16 - 22; Động vật có xương sống: 39 - 44. Diagnosis: Body slender to moderately deep, its depth 17-30% of standard length; scutes beginning behind base of first pectoral finray, with 8-15 pre-pelvic and 6-10 post-pelvic scutes, and a total of 17-23 scutes, first pre-pelvic scute as long as following scutes lacking ascending arms; lower jaw very slightly projecting, teeth at symphysis only slightly enlarged; pre-maxillary teeth small and inward pointing, only the tips usually apparent, no strongly marked indentation at centre of jaw; lower gillrakers 20-35, equal to or longer than corresponding gill filaments; silver stripe along flank (Ref. 188, 2244, 81269, 81631). It resembles Pellonula vorax, which has larger and straighter teeth, often pointing forward, and scutes before pectoral fin bases (Ref. 188, 2244, 81269, 81631). The absence of large canine teeth in upper jaw distinguishes it from Odaxothrissa; Microthrissa species are deep-bodied and have a much more slender maxilla compared to Pellonula leonensis (Ref. 188).

Sinh học     Tự điển (thí dụ epibenthic)

Found chiefly in rivers and streams, also man-made and natural lakes (Ref. 188); also in estuaries and lagoons (Ref. 188, 2683). Apparently able to tolerate moderate or even quite high salinities (Ref. 188). It forms enormous shoals in both inshore and offshore regions of Lake Kainji (Ref. 3034). It feeds on terrestrial and aquatic insects, but also ostracods and entomostracans; stomachs containing clupeid fish scales may represent cannibalism (Ref. 188). Reproduction occurs in rivers and lakes, and may be also in estuaries and coastal lagoons (Ref. 2683). It breeds from July to September in Lake Volta (Ref. 188).
