The Karo or Kara are a small tribe with an estimated population between 1,000 and 3,000, living along the east banks of the Omo River. They paint their bodies and faces with white chalk, mixed with yellow rock, red iron ore or charoal to give it colour. Face masks are worn at times and they have clay hair buns with feathers in them. Red clay mixed with butter is put into their hair and clothing is made from animal skin. The women scar their chest believing it makes them beautiful. A man's scars represent an enemy or dangerous animal killed.
