The harpy eagle is the world's biggest bird of prey, but smaller creatures have far greater impact.

As the Pantanal switches from grassland to swamp and back, jaguar and caiman rule in turn.

The grassland region is Brazil's least-known habitat, defined by fires and dramatic thunderstorms.

Brazil's coast stretches from the temperate waters of the south to the equator and beyond.
