King rail
This rail forages in shallow water near cover and eats mainly aquatic insects and crustaceans. It forages by probing the mud while moving around in shallow water.
Water buffalo
Water buffalo thrive on many aquatic plants. During floods, they will graze submerged, raising their heads above the water and carrying quantities of edible plants. Water buffalo eat reeds, "Arundo donax", a kind of "Cyperaceae", "Eichhornia crassipes", and "Juncaceae". Some of these plants are of great value to local peoples. Others, such as "E. crassipes", are a major problem in some tropical valleys and water buffalo may help to keep waterways clear.
