Ilha Grande is one of the most pristine remnants of Brazil's Atlantic
rainforest, one of the richest ecosystems in the world, and a hotspot for
biodiversity and conservation. It holds some of the largest remaining
populations of many endangered species, including the red-ruffed fruitcrow
(Pyroderus scutatus), the brown howler monkey (Alouatta fusca), the maned sloth
(Bradypus torquatus) the red-browed Amazon parrot (Amazona rhodocorytha), and
the broad-snouted caiman (Caiman latirostris). The seas around the island, which
are also protected, feature a unique convergence of tropical, subtropical, and
temperate-zone
