The Cervo-do-Pantanal (Blastocerus dichotomus), also called  Cervo, Suaçuetê, Suaçupucu e Veado-galheiro is a ruminant mammal of the family of deer and lives only in Pantanal and Chaco, usually with the water level reaching half a meter deep. They are swift swimmers. The marshes with their high vegetation density protect them from predators and provide them with food. They possess very large ears lined with white hairs, reddish brown coloured body and long dark legs. The hair turns darker during winter. There are also white marks on the hips and around the eyes. The legs are black below the tarsal as is the muzzle. The tail is of a paler reddish tone than the rest of the body on its upper part and black on the under part. The head-and-body length is 153 to 200 cm. Their main predators are the Onça Pintada and the Suçuarana.
