These are Nachuna and her baby Olabile and Nachare and her baby Olakibo from the Surma tribe. As well as lip plates, the Surma girls mark their bodies permanently by scarification. The skin is lifted with a thorn then sliced with a razor blade, leaving a flap of skin which will eventually scar. The men, meanwhile, scar their bodies to show they've killed someone from an enemy tribe. There are particular meanings assigned to these scars. One group, for instance, cuts a horseshoe shape on their right arm to indicate they've killed a man, and on their left for a woman. Omo Valley, Southern Ethiopia, 2013.
