Although many previous classifications recognized as few as a single all-inclusive species, there are now at least eight that are considered valid: the Sunda slow loris (N. Slow lorises have a toxic bite, a trait rare among mammals and unique to lorisid primates. Slow lorises have a round head, a narrow snout, large eyes, and a variety of distinctive coloration patterns that are species-dependent.They are thought to have reached the islands of Sundaland when the Sunda Shelf was exposed at times of low sea level, creating a land bridge between the mainland and islands off the coast of Southeast Asia.The earliest known mention of a slow loris in scientific literature is from 1770, when Dutchman Arnout Vosmaer (1720–1799) described a specimen of what we know today as N.

Found in Southeast Asia and bordering areas, they range from Bangladesh and Northeast India in the west to the Sulu Archipelago in the Philippines in the east, and from Yunnan province in China in the north to the island of Java in the south. The hands and feet of slow lorises have several adaptations that give them a pincer-like grip and enable them to grasp branches for long periods of time.bengalensis that he had received two years earlier. In 2008, Groves and Ibnu Maryanto confirmed the promotion of the fifth species, the Javan slow loris, to species status, a move that had been suggested in previous studies from 2000.The French naturalist Georges-Louis Leclerc, Comte de Buffon, later questioned Vosmaer's decision to affiliate the animal with sloths, arguing that it was more closely aligned with the lorises of Ceylon (now Sri Lanka) and Bengal. They based their decision on an analysis of cranial morphology and characteristics of pelage.Later 19th-century authors also called the slow lorises Nycticebus, but most used the species name tardigradus (given by Linnaeus in 1758 in the 10th edition of Systema Naturæ) for slow lorises, until mammalogists Witmer Stone and James A. Rehn clarified in 1902 that Linnaeus's name actually referred to a slender loris. This hypothesis was corroborated by a 2007 study that compared the variations in mitochondrial DNA sequences between N. coucang, and suggested that there has been gene flow between the two species. borneanus—were elevated to species status, and a new species—N. Rachel Munds, Anna Nekaris and Susan Ford based these taxonomic revisions on distinguishable facial markings.while in 2001 Groves opined there were three species (N. In 2012, two taxonomic synonyms (formerly recognized as subspecies) of N. Similar to the slender lorises, the fur around and directly above the eyes is dark.
