Author 'Boucher Marc dit de Meilh' (Id 221187 ) : Two Cobes of Mrs Gray (Kobus megaceros) (or cobe de Lechwe Nile) at the edge of the water, but disturbed by a few 'holdouts' aquatic... It is, in fact, a medium-sized antelope. The female is smaller than the male. Only the male has horns. This mammal swims very well and also knows how to engage in land 'muddy' due to the shape of its hooves. Ph : Marc de Meilhan.
