The pygmy three-toed sloth, also known as the monk sloth or dwarf sloth, are found on a small island off the coast of Panama. This sloth, like other sloths, is arboreal (tree-living) and feeds on leaves. It is symbiotically associated with green algae, that can provide it with a camouflage. The IUCN lists the pygmy three-toed sloth as critically endangered. Threats to the sloth's survival include timber harvesting and human settlement, that might lead to habitat degradation.

The Slender loris, is a nocturnal primate. They are subdivided into two known species, namely red slender loris and grey slender loris. The red slender loris found in Sri Lanka, are classified as Endangered by the IUCN, it is declining because its forest habitat is being destroyed for logging, agriculture and development.

This peaceful creature with distinctive black and white coat is adored by the world and considered a national treasure in China. Despite their exalted status and relative lack of natural predators, pandas are still at risk.

Red Pandas are such beautiful creatures. One of its kind. Sadly they are endangered due to deforestation.

Tarsiers are nocturnal creatures. So beautiful and unique. They hunt by sight and sound and have the biggest eyes in the animal kingdom due to which they are difficult to rotate. But there is a joint between the base of their skull and spine which allows them to rotate their head 360 degrees, almost similar to owls. The majority of Tarsier species are now endangered or threatened, and some are designated critically endangered. Threats include habitat destruction and fragmentation, hunting, agricultural pollutants and human disturbance. Tarsiers are very shy animals that prefer to stay away from human contact.

The Iberian lynx is the world's most threatened species of cat. They are classified as Critically Endangered (CR).

The International Union for the Conservation of Nature (IUCN) lists 26 bat species as Critically Endangered, meaning they face an imminent risk of extinction. Fifty-one others are Endangered, and 954 bat species are considered Vulnerable. Bats also are among the most under-studied of mammals. The IUCN lists 203 bat species as “Data Deficient”– there is simply too little information available to determine their conservation status, and over 150 newly described species have yet to be added to the IUCN Red List and have yet to be formally assessed.

Orang-utan means 'man of the forest' in Malay language. They are the world's largest tree-climbing mammals. But their forest habitat in Indonesia and Malaysia is rapidly disappearing, putting the future of Asia's only great ape in peril. They are Critically Endangered (CR). Orang-utans are known as gardeners of the forest. They play a vital role in seed dispersal and in maintaining the health of the forest ecosystem, which is important for people and a host of other animals.

Lion-Tailed Macaque are so beautiful. I actually saw them once few years ago.
They live in the forested areas of the great Western Ghats, a mountain range in southwest India. Unfortunately these beautiful animals are endangered. The biggest threat they are facing is deforestation. Also in some areas, they are caught as pets and also hunted for food.
