Introduction
Slow lorises are a group of five species of strepsirrhine primates, which make up the genus Nycticebus. Found in South and Southeast Asia, they range from Bangladesh and Northeast India in the west to the Philippines in the east, and from the Yunnan province in China in the north to the island of Java in the south. Although many previous classifications recognized fewer species, five are now considered valid: the Sunda slow loris (N. coucang), Bengal slow loris (N. bengalensis), pygmy slow loris (N. pygmaeus), Javan slow loris (N. javanicus), and Bornean slow loris (N. menagensis). (Wiens 2002). All of these five speices are now enlisted as the top 25 endangered primates on the ICUN redlist.

Slow lorises are also particularly vulnerable to habitat destruction and the felling of feed and sleeping trees causes habitat degradation and increased contact with people. Slash-and-burn cultivation is also a significant habitat threat in India, as is tea cultivation and other agricultural land use. Often human settlements follow these types of land use, inhibiting secondary growth. Alternate reasons for habitat destruction are logging, fuel-wood extraction, land use for paper production, and the construction of infrastructure. In China, habitat destruction is also the biggest threat to resident slow lorises and suitable areas are often destroyed for cash crops such as rubber, sugarcane, and coffee growing. Sometimes slow lorisies are imported to alien spaces, when they are not familiar with the areas it becomes difficult to survive in unknown environments. Over large areas of their range, slow lorises are collected as pets and for illegal folk medicine. They are one of the most commonly traded protected primates in Southeast Asia. They are also hunted for meat at times, which contributes as a threat to their kind. Even if the lorises are not desired locally, they are often collected in neighboring areas and imported. In China, slow lorises are eaten; the bones are used for medicinal uses, and the fur for local hunting bags. There is also evidence of illegal trade of their species as they are found in Indonesian and Cambodian markets for sale. In Vietnam, collection for medicinal purposes results in captured animals being dried or placed in rice wine. Adding to the threat of their removal from their habitats, slow lorises very often die from the stress of being held captive.
