The forest floor is flooded, primitive boto dolphins weave through the tree trunks, arowhanas (“water-monkeys”) spring from the water to snatch food from the trees. In the canopy above lives the strangest monkey in the world, the white-furred uakari.

In the dry season insects are abundant near the forest floor, huge numbers of giant river turtles come to nest on the beaches, crowded aquatic life takes on a totally different nature.
