As the waters of the Amazon and its tributaries reach their lowest, torrential rain begins to beat down with brutal force. In a few months’ time, the forest will be submerged under almost thirty meters of water: enough to swallow up a ten-storey building! The youngest animals are dealing with the deluge for the first time in their lives. We follow them all: the sloth, terribly vulnerable; the opossum, the only marsupial outside Oceania; the harpy eagle, one of the greatest in the world; the shy, solitary armadillo; the squirrel monkey, a treetop acrobat… and many other inhabitants of a gleaming, transfigured world shown in this way for the first time.
