Bearded Saki Monkey
The Bearded Saki Monkey is a large, robust primate found in the rainforests of South America. It has a thick, shaggy coat and a prominent beard, giving it its name. Bearded Sakis are known for their powerful jaws, which they use to crack open hard nuts and seeds. They live in large groups and are highly social, often seen foraging in the treetops. These monkeys play an essential role in seed dispersal throughout the forest.
Woolly Opossum
The Woolly Opossum is a small marsupial native to the rainforests of Central and South America. It has soft, wool-like fur and a prehensile tail used for climbing. Woolly Opossums are nocturnal and arboreal, spending most of their lives in the treetops. They feed on fruits, insects, and small vertebrates, playing a key role in pest control. Their solitary nature and elusive behavior make them difficult to spot in the wild.
Amazonian Manatee
The Amazonian Manatee is a large aquatic mammal found only in the rivers and flooded forests of the Amazon Basin. It has a smooth, thick body and flippers adapted for swimming through dense vegetation. This herbivorous mammal feeds on aquatic plants, consuming large quantities daily to sustain its massive size. Amazonian Manatees are slow-moving and gentle, often seen grazing in shallow waters. Their presence helps control the growth of aquatic vegetation, maintaining the balance of the ecosystem.

Their long fingers and claws help them extract food from tree bark and crevices.
Brown-Throated Sloth
The Brown-Throated Sloth is a slow-moving, tree-dwelling mammal found in Central and South America. It has shaggy fur, often covered in algae, which helps it blend into its environment. These sloths feed primarily on leaves, which they digest slowly due to their low metabolism. They spend most of their lives hanging upside down from tree branches. Despite their sluggish appearance, they are excellent swimmers and will often move through rivers to find new territories.
Sunda Colugo
The Sunda Colugo, also known as the flying lemur, is a gliding mammal native to Southeast Asia’s rainforests. It has large, membrane-covered limbs that allow it to glide long distances between trees. Colugos are nocturnal, feeding on young leaves, flowers, and fruits. They are highly adapted to life in the canopy, where they move slowly but efficiently.
