In the world’s largest wetland water dictates the rhythm of life. With the summer rains the Paraguay River and its tributaries overflow to the large expanses of lowlands around changing landscape abruptly. Green fields of grasses transmutate into temporary rivers. Colourful aquatic plants sprout from the ground originating aquatic gardens inhabited by myriads of fish. Attracted by the easy food Caimans feast on the passing shoals. At this time, even terrestrial species such as Jaguars, collared peccary go to the water. Swim, dive, float. The Pantanal horse graze on submerged grass. All animals and even men get an amphibian life when the great Pantanal plains becames a inner freshwater sea.
