Denticle herring
The denticle herring is a small, up to long, species of ray-finned fish found only in the rivers of Benin, Nigeria, and western Cameroon. It is related to the herrings, but notable for its large anal fin and its array of denticle-like scales under the head, which give it almost a furry appearance. It is the sole living member of the family Denticipitidae.
