Mursi tribeswoman sticking out her tongue, lower lip stretched to accommodate large clay lip plate. Omo Delta, Ethiopia, Africa. The Omo delta is an area where the way of life remains largely untouched by the 21st century, and local tribes each have their own unique customs and rituals. Body adornment can be extreme, such as in the case of the Mursi women who insert a clay lip plate, up to 7 inches (16cm) in diameter, in their lower lip. Decorative scarification, and bodies painted with white or ochre clay, are combined with ornate beadwork and striking headdresses.
