The Mundari, like other Nilotic tribes, are so cattle-oriented: cattle serves as a form of currency and a mark of status. Marriages are arranged by the prospective groom offering cattle to the bride’s family and husbands may take as many wives as they can support. The Mundari engage in perennial cattle raiding wars with the Bor Dinka during the dry season.
Mundari men sometimes bathe their hair in cow urine; the uric acid gives the hair a red, yellow, or orange color, which they regard as beautiful.
The Mundari also cultivate sorghum and catch fish using nets and spears.
In common with other Nilotic tribes in South Sudan, the Mundari practice ritual scarification as a rite of passage into adulthood for young men. The typical Mundari scar pattern consists of two sets of three parallel lines, each on either side of the forehead, extending in a downward slope and unconnected in the middle.
