The Puku is a medium-sized antelope that lives in the wet grasslands of Africa. It is sandy brown in color, with a slightly lighter brown underbelly. Its coat is rougher than the similar-sized southern reedbuck, lechwe or impala, or the smaller oribi. Males have ridge-structured horns. Puku are found almost exclusively in marshy grassland where they eat grasses. They active in the early morning and late afternoon. Females gather in herds of up to 20 individuals. During the rainy season, herds will come together for added safety, typically reaching around 50 females.
