Deforestation and conflict in their region have severely threatened their survival.
Sunda Pangolin
The Sunda Pangolin is a scaly mammal found in the forests of Southeast Asia. It is covered in hard, overlapping scales made of keratin, providing it with armor-like protection. This nocturnal creature feeds primarily on ants and termites, using its long, sticky tongue to capture its prey. When threatened, it curls into a tight ball. Unfortunately, the illegal wildlife trade has made the Sunda Pangolin critically endangered.
Tarsier
The Tarsier is a small primate with enormous eyes, found in the jungles of Southeast Asia. It is known for its incredible leaping ability, jumping from tree to tree with ease. These nocturnal creatures have sharp claws and long fingers, helping them grasp branches tightly. Tarsiers feed mainly on insects, using their keen eyesight to hunt in the dark. Habitat destruction has put them at risk, with many species facing declining populations.
Bengal Slow Loris
The Bengal Slow Loris is a nocturnal primate found in the forests of South and Southeast Asia. It has large, round eyes and a slow, deliberate way of moving through the trees. This loris has a unique defense mechanism, producing a toxic substance from glands on its elbows, which it can use to deter predators. Its diet consists of fruits, insects, and small animals. Deforestation and the illegal pet trade have greatly threatened its existence.
Spectacled Bear
The Spectacled Bear is the only bear species native to South America, found in the cloud forests of the Andes.
