Like all other horns of antelopes, the core of a bongo's horn is hollow and the outer layer of the horn is made of keratin, the same material that makes up human fingernails, toenails, and hair. The bongo runs gracefully and at full speed through even the thickest tangles of lianas, laying its heavy spiralled horns on its back so the brush cannot impede its flight. Bongos are hunted for their horns by humans.Walther, F. R. (1990) "Spiral-horned antelopes". In Grzimek's Encyclopedia of Mammals. S. P. Parker (ed.). New York: McGraw-Hill. Volume 5, pp. 344–359.
