UNESCO says:
This huge 1.5 million-ha park has successive tiers of vegetation rising from 150 to 4,200 m above sea-level. The tropical forest in the lower tiers is home to an unrivalled variety of animal and plant species. Some 850 species of birds have been identified and rare species such as the giant otter and the giant armadillo also find refuge there. Jaguars are often sighted in the park.

Alternatively named Manu Biosphere. Probably the most diverse habitat of South America, both plants & animals. For those in search of larger animals, see tapirs & jaguars, giant otters & armadillos, parrots & macaws.
