Shaded from the hot sun, a Karo woman grinds sorghum using large flat stones. It is customary for females of the tribe when in their teens to make a small hole in the flesh below their lower lips into which they put an ornament; this woman has used a small nail. Numerous heavy metal bracelets are worn by married women.The Karo are a small tribe living in three main villages along the lower reaches of the Omo River in southwest Ethiopia. The largest village, Duss, is home to almost half the population of around 3,500 people. Once solely agriculturalists, the people now keep livestock as well.They are Omotic people and speak a dialect of their larger and more powerful neighbours, the Hamar, from whom they originated in the distant past.
