According to From Wikipedia:


Slow lorises

These slow moving strepsirrhine primates range from Borneo and the southern Philippines in Southeast Asia, through Bangladesh, Vietnam, Southern China (Yunnan area) and Thailand. Adult slow lorises range in size from 21 to 38 cm, depending on the species, and weigh up to 2 kilograms. The tail is a mere stump. The short, thick fur can have a variety of colours, mostly grey-reddish and often with whitish undertones. They have well developed thumbs, which they use to grasp and hold fast to branches, and a very flexible back. The eyes are large and the ears are small and nearly hidden in the fur. Like all lorises, slow lorises are nocturnal and arboreal animals that prefer the tops of the trees. Also, they have slow, deliberate movements and a powerful grasp that makes them very difficult to remove from branches. They live as solitaries or in small family groups.
