A Karo man with braided hair plays a traditional stringed instrument beside the Omo River near Duss. Young men settle disputes by fighting with hippo hide whips, which leave nasty weals on a person's skin, as evidenced on the biceps and forearm of the young man in this picture.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.
