Habitat . [78], Slow lorises are found in South and Southeast Asia. Population. Figure:Rescued Bengal Slow Loris. Its geographic range is larger than that of any other slow loris species. [36] However, in 1939 Reginald Innes Pocock consolidated all slow lorises into a single species, N. coucang,[37] and in his influential 1953 book Primates: Comparative Anatomy and Taxonomy, primatologist William Charles Osman Hill also followed this course. Depending on the species, they live in both tropical regions with high rainfall, and subtropical regions with less rainfall. [60] The skull has prominent crests (ridges of bone). [92][93] In the absence of direct studies of the genus, primatologist Simon Bearder speculated that slow loris social behavior is similar to that of the potto, another nocturnal primate. Its dorsal fur is light brown, with much lighter ventral fur. [143][121][142] According to data compiled from monthly surveys and interviews with local traders, nearly a thousand locally sourced slow lorises exchanged hands in the Medan bird market in North Sumatra during the late first decade of the 21st century. The limited information on its status and ecology is the main hindrance to developing a conservation strategy for this species in India. 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. [8][63] This gives their hands and feet a pincer-like appearance. [90], Little is known about the social structure of slow lorises, but they generally spend most of the night foraging alone. [16] 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. Slow loris venom was known in folklore in their host countries throughout southeast Asia for centuries, but dismissed by western scientists until the 1990s. The Bengal slow loris (nycticebus bengalensis), an endangered species of primate locally known as lajjaboti banor, are on the verge of disappearing due to extensive deforestation, researchers and environmentalists said.As deforestation has destroyed much of their natural habitat and sources of food, lorises are now entering into nearby localities of Chittagong. Secondary toxins may be introduced from the consumption of wild food, augmenting the toxicity. [8] They will also grip branches with only their hind feet, lift themselves upright, and quickly launch forward with their hands to catch prey. These little guys are under 10 inches long from head to tail, and weigh only 6 pounds. [68][69] The toothcomb is kept clean by the sublingua or "under-tongue", a specialized structure that acts like a toothbrush to remove hair and other debris. A survey by primatologist Anna Nekaris and colleagues (2010) showed that these belief systems were so strong that the majority of respondents expressed reluctance to consider alternatives to loris-based medicines. It is found in parts of Yunnan and southwest Guangxi, China, and has been recorded in Bangladesh’s Chittagong Hill Tracts. "On the early editions of Lacépède's "Tableaux des mammifères et des oiseaux", with remarks on two hitherto overlooked species: "Classification des oiseaux et des mammifères", "Vet Describes the Plight of Indonesia's Primates", "Taxonomy of the Bornean slow loris, with new species, "Extreme primates: Ecology and evolution of Asian lorises". Some species also live in agricultural areas, like plantations. The Sunda slow loris (Nycticebus coucang) or greater slow loris is a strepsirrhine primate and a species of slow loris native to Indonesia, West Malaysia, southern Thailand and Singapore.It measures 27 to 38 cm (11 to 15 in) from head to tail and weighs between 599 and 685 g (21.1 and 24.2 oz). [77], The second digit of the hand is short compared to the other digits,[63] while on the foot, the fourth toe is the longest. Slow loris brachial gland exudate (BGE) has been shown to possess up to 142 volatile components, and possesses a variant of the cat allergen protein Fel-D1. We conducted an 18 mo study from June 2008 to December 2010 in Hollongapar Gibbon Wildlife Sanctuary, Assam, India, to investigate whether Bengal slow lorises prefer gum, and whether there is any evidence of second-ary metabolites in their diet. Slow lorises are nocturnal strepsirrhine primates in the genus Nycticebus that live in the rainforests of South and Southeast Asia. Each of the slow loris species that had been identified prior to 2012 is listed as either "Vulnerable" or "Endangered" on the IUCN Red List. The bony palate (roof of the mouth) only goes as far back as the second molar. For example, slow lorises can feed on Gluta bark, which may be fatal to humans. Their evolutionary history is uncertain since their fossil record is patchy and molecular clock studies have given inconsistent results. [72] Slow lorises have stout bodies,[63] and their tails are only stubs and hidden beneath the dense fur. 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. coucang), Bengal slow loris (N. bengalensis), pygmy slow loris (N. pygmaeus), Javan slow loris (N. javanicus), Philippine slow loris (N. menagensis), Bangka slow loris (N. bancanus), Bornean slow loris (N. borneanus), and Kayan River slow loris (N. kayan). [74] This gives them greater mobility when twisting and extending towards nearby branches.
