definition
Any of several species of small southern African antelopes of the Cephalophinae subfamily.
Duikers are animals of small or medium size, usually frequenting thick forest.
The duikers, or duikerboks (Cephalophus), of Africa, which range in size from a large hare to a fallow-deer, typify the subfamily Cephalophinae, characterized by the spike-like horns of the bucks, the elongated aperture of the face-glands, the naked muzzle, the relatively short tail, and the square-crowned upper molars; lateral hoofs being present.
In the duikers themselves the single pair of horns is set in the midst of a tuft of long hairs, and the face-gland opens in a long naked line on the side of the face above the muzzle.
They range in size from the tiny duikers to the huge cape buffalo.
