Diagnosis: Denticeps clupeoides is closely related to the Clupeidae, characterised by the presence of midventral scutes; it is distinguished from all clupeids by the presence of numerous small denticles on the surface of the dermal head bones (odontodes) and a complete lateral line along the entire length of the sides (Ref. 2848, 81268, 81632, 117233). Unlike the majority of African freshwater clupeids, Denticeps clupeoides lacks a supramaxilla (Ref. 2848, 81268).
Found in streams with water of low ionic content; it always occurs in shoals that tend to keep to the middle of the stream, where the current is at its strongest (Ref. 81632, 101724). It is a skilled and untiring swimmer, extremely fast and hence not easily caught (Ref. 81632, 101724). Peak spawning period in Cross River occurs from July to August (Ref. 85170).
