Which clupeiform fish species live in rivers and lakes of Central and West Africa?

In the rivers and lakes of Central and West Africa, there are nine genera comprising 15 species of freshwater clupeiform fishes.1

Among these is the denticle herring, Denticeps clupeoides, which is the most primitive living clupeiform. It is found in fast-running, clear water within medium-sized streams in Nigeria and Cameroon. While the order Clupeiformes is primarily marine, these specific species have adapted to freshwater environments in the region.21
