[58] Like other lorisids, their snout does not taper towards the front of the face as it does in lemurs, making the face appear less long and pointed. Sunda slow lorises mainly inhabit primary and secondary tropical lowland forests. [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. [90], Little is known about the social structure of slow lorises, but they generally spend most of the night foraging alone. [113] The pygmy slow loris often returns to the same gum feeding sites and leaves conspicuous gouges on tree trunks when inducing the flow of exudates. 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. It prefers rainforests with dense canopies, and its presence in its native habitat indicates a healthy ecosystem. [129] Infection, stress, pneumonia, and poor nutrition lead to high death rates among pet lorises. [109] In captive Sunda slow lorises, mating primarily occurs between June and mid-September, with the estrus cycle lasting 29 to 45 days and estrus lasting one to five days. [11], Lorises first appear in the Asian fossil record in the Miocene, with records in Thailand around 18 million years ago (mya)[12] and in Pakistan 16 mya. [105], Studies suggest that slow lorises are polygynandrous. [22], Slow lorises range in weight from the Bornean slow loris at 265 grams (9.3 oz) to as much as 2,100 grams (74 oz) for the Bengal slow loris. [130], Slow lorises are sold locally at street markets, but are also sold internationally over the Internet and in pet stores. [65][129] In March 2011, a newly posted video of a slow loris holding a cocktail umbrella had been viewed more than two million times, while an older video of a slow loris being tickled had been viewed more than six million times. As with many nocturnal prosimian species, little is known about its behavior or ecology; even less information is available on its distribution and population status in northeastern India. They are heavier than all other loris species with a mass between one and two kg and a length of 26 to 38 cm, being more than three times the weight of the smallest loris… [79] They are found in India (Northeastern states),[79][80][81] China (Yunnan province), Laos, Vietnam, Cambodia, Bangladesh, Burma, Thailand, Malaysia, the Philippines, Indonesia,[79] Brunei,[82] and Singapore. 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. Bengal slow loris is facing habitat loss due to felling of roosting and feeding trees across its range. They make poor pets as they are nocturnal, have specialized diets, are difficult to care for, and often die from infection, blood loss, improper caring and handling or inadequate nutrition. Our websites use cookies (session, persistent, third party, advertising and performance) so they function correctly, to help us improve them and for targeted advertising. [126][136][137], Within their countries of origin, slow lorises are very popular pets,[138] particularly in Indonesia. largest of the lorises, the Bengal slow loris Nycticebus bengalensis. The first mandibular premolar is elongated, and the last molar has three cusps on the crown, the shortest of which is near the back. [129][137], Despite frequent advertisements by pet shops in Japan, the World Conservation Monitoring Centre reported that only a few dozen slow lorises were legally imported in 2006, suggesting frequent smuggling. It is possible that this layer blurs the images they see, as the reflected light may interfere with the incoming light. These little guys are under 10 inches long from head to tail, and weigh only 6 pounds. [43], Slow lorises have a round head[57] because their skull is shorter than in other living strepsirrhine. They lack the opsin gene that would allow them to detect short wavelength light, which includes the colors blue and green. [59] Compared with the slender lorises, the snout of the slow loris is even less pointed. The Bengal slow loris is nocturnal and arboreal, occurring in both evergreen and deciduous forests. [8][75][76] The toes have a large flexor muscle that originates on the lower end of the thigh bone, which helps to impart a strong grasping ability to the hind limbs. It also has the largest size. There are five species of slow Loris: the Bengal, Bornean, Javan, pygmy and Sunda slow Loris. To protect itself, the Slow loris has also been observed to rub the venom on its fur. The Bengal slow loris Nycticebus bengalensis is a nocturnal prosimian that inhabits the forests of northeastern India. The preferred habitats of the Bengal slow loris range across tropical and subtropical regions, and include evergreen and semi-evergreen rainforests with forest edges and continuous, dense canopies. 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. The Nycticebus bengalensis or the Bengal slow loris is a slow loris species that is native to Indochina and the Indian subcontinent. Their exact … Bengal slow lorises (Nycticebus bengalensis) are anything but ordinary.Known as lajwanti banor, or ‘shy monkey’ in Bangla, they are anatomically and behaviourally peculiar.The English name ‘slow loris’ is a misnomer, conjuring images of a sloth-like existence. They possess a dual composite venom consisting of saliva and brachial gland exudate, a malodourous fluid forming from an apocrine sweat gland on the animal's forearm. Rachel Munds, Anna Nekaris and Susan Ford based these taxonomic revisions on distinguishable facial markings. [110] The Sunda slow loris eats insects that other predators avoid due to their repugnant taste or smell. Oxford Brookes University Headington Campus Oxford OX3 0BP UK +44 (0) 1865 741111. This species is also known by the following name(s): Northern Slow Loris, N. cinereus, N. incanus, N. tenasserimensis. Deep-rooted beliefs about the supernatural powers of slow lorises, such as their purported abilities to ward off evil spirits or to cure wounds, have popularized their use in traditional medicine. The slow loris is endangered due to both habitat loss and hunting for illegal pet and traditional medicine trades. [136] As many as 95% of the slow lorises rescued from the markets die of dental infection or improper care. We are always there to serve the slow Loris. [124][132] Surveys are needed to determine existing population densities and habitat viability for all species of slow loris. Ben­gal slow lorises are noc­tur­nal and ar­bo­real strep­sir­rhines. Despite local laws prohibiting trade in slow lorises and slow loris products, as well as protection from international commercial trade under Appendix I, slow lorises are openly sold in animal markets in Southeast Asia and smuggled to other countries, such as Japan. Figure:Rescued Bengal Slow Loris. These lorises can be divided into two genera. The first genus is Loris. [120] Loris bites cause a painful swelling, and the single case of human death reported in the scientific literature was believed to have resulted from anaphylactic shock. [57] As with other members of Lorisidae, its interorbital distance is shorter than in lemurs. [131], Since 2007, all slow loris species have been protected from commercial international trade under Appendix I of CITES. We compared the density and microhabitat selection of a nocturnal arboreal primate, the Bengal slow loris (Nycticebus bengalensis), in mostly undisturbed, evergreen tropical forest to those in 15–18 year old Acacia/Leucaena plantations with significant secondary regrowth, … According to Nekaris, this adaptation—along with vocalizations, movement, and coloration patterns similar to those of true cobras—may have evolved through Müllerian mimicry to protect slow lorises when they need to move across the ground due to breaks in the canopy. What we know about the slow loris is very limited as their behavior in the wild is difficult to study due to their rainforest habitat and nocturnal and cryptic (often relatively solitary, silent and inconspicuous) lifestyles. These prosimians (the oldest, most “primitive” order of primates) are typically found in tropical, subtropical, evergreen, and semi-evergreen forests. Because, we returned him to his natural habitat. Scientific Name: Loris tardigradus Commonly found in the tropical scrub and deciduous forests as well as the dense hedgerow plantations bordering farmlands of Southern India and Sri Lanka, the Slender Loris is a small, nocturnal primate. Of all the loris species, the Bengal slow loris occupies the greatest and northernmost range, with the largest populations living in eastern Thailand. [128], Each of the slow loris species that had been identified prior to 2012 are currently listed as either "Vulnerable" or "Endangered" by the International Union for Conservation of Nature (IUCN) on their Red List. Slow lorises are a group of several species of nocturnal strepsirrhine primates that make up the genus Nycticebus. kayan). Animal dealers in Southeast Asia keep tanks of water nearby so that in case of a bite, they can submerge both their arm and the slow loris to make the animal let go. In Vietnam, the species can be found in secondary forest, at the edge of primary forest, and on agricultural land and bamboo forest. [137] According to Nekaris, these videos are misunderstood by most people who watch them, since most do not realize that it is illegal in most countries to own them as pets and that the slow lorises in the videos are only docile because that is their passive defensive reaction to threatening situations. In some parts of Asia it is known as the animal which can cure 100 diseases. In captivity, they can live 20 or more years. [133] Despite their CITES Appendix I status and local legal protection, slow lorises are still threatened by both local and international trade due to problems with enforcement. Slow loris inflicted wounds is a major cause of premature death in zoo and wildlife slow loris populations; often resulting in festering and necrotic wounds. Common health problems seen in pet slow lorises include undernourishment, tooth decay, diabetes, obesity, and kidney failure. [127] Slow lorises have lost a significant amount of habitat,[128] with habitat fragmentation isolating small populations and obstructing biological dispersal. he Bengal slow loris Nycticebus bengalensis is the only strepsirrhine primate in north-east India. We compared the density and microhabitat selection of a nocturnal arboreal primate, the Bengal slow loris (Nycticebus bengalensis), in mostly undisturbed, evergreen tropical forest to those in 15–18 year old Acacia/Leucaena plantations with significant secondary regrowth, … The face is creamy white with triangular patches of dark fur around the eyes, which are occasionally connected via a fork to the dark stripe on the head. 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. Likewise, gestation lasts 185 to 197 days, and the young weigh between 30 and 60 grams (1.1 and 2.1 oz) at birth. Thailand is home to two species of slow loris; the greater slow loris (Nycticebus coucang) and the Bengal slow loris (Nycticebus bengalensis). [99], If cornered, they may adopt a defensive posture by curling up and lunging at the predator. [121] Slow lorises (of the genus Nycticebus) are accepted as the only known venomous primate. [22][68] As in all other crown strepsirrhines, their lower incisors and canine are procumbent (lie down and face outwards), forming a toothcomb, which is used for personal and social grooming and feeding. The study of slow loris venom was brought to the public attention in 2012 by the research of the world-renowned Professor K. A. I. Nekaris and in her award-winning BBC documentary, The Jungle Gremlins of Java. Females reach sexual maturity at 18 to 24 months, while males are capable of reproducing at 17 months. This arboreal and nocturnal species lives in tropical and sub-tropical evergreen and semi-evergreen rainforests, preferring areas with dense canopy cover, as well as forest edges, where insect prey appear to be more abundant. Photo Taken At Endangered Primate Rescue Center, Cuc Phuong National Park, Ninh Binh Province, Vietnam. (1996) recorded Bengal slow lorises [102] Other potential predators include cats, sun bears (Helarctos malayanus), binturongs (Arctictis binturong), and Asian palm civets.

We are always there to serve the slow Loris. Although most of the recognized lineages of Nycticebus (including N. pygmaeus, N. menagensis and N. javanicus) were shown to be genetically distinct—the analysis suggested that DNA sequences from some individuals of N. coucang and N. bengalensis apparently share a closer evolutionary relationship with each other than with members of their own species. The Bengal slow loris is nocturnal and arboreal, occurring in both evergreen and deciduous forests. [75][95], Slow lorises are slow and deliberate climbers, and often hold on to branches with three of their four limbs. Rovero, F., Mtui, A., Kitegile, A., Jacob, P., Araldi, A., and Tenan, S. (2015). [75][89] They prefer forests with high, dense canopies,[63][88] although some species have also been found in disturbed habitats, such as cacao plantations and mixed-crop home gardens. Slow lorises have their teeth cut or pulled out for the pet trade. The Bengal slow loris (Nycticebus bengalensis) or northern slow loris is a strepsirrhine primate and a species of slow loris native to the Indian subcontinent and Indochina. Some species also live in agricultural areas, like plantations. [67], The dental formula of slow lorises is 2.1.3.32.1.3.3 × 2 = 36, meaning that on each side of the mouth there are two upper (maxillary) and lower (mandibular) incisors, one upper and lower canine tooth, three upper and lower premolars, and three upper and lower molars, giving a total of 36 permanent teeth. [41], In 2006, the Bornean slow loris was elevated to the species level (as Nycticebus menagensis) based on molecular analysis of DNA sequences of the D-loop and the cytochrome b gene. I think this one is a big achievement for us. PASIGHAT, May 18: Being disturbed in its habitat and suffered from food scarcity, Bengal Slow Loris – the most leisure primate species remaining in Arunachal forests is reported to be strayed in human habitations time to time. In the next morning they released that Loris in the Satchari National Park. [83], There are currently eight recognized species. [140][144] The slow lorises found in animal markets are usually underweight and malnourished, and have had their fur dyed, which complicates species identification at rescue centers. [63][75] They can tightly grasp branches with little effort because of a special muscular arrangement in their hands and feet, where the thumb diverges at nearly 180° from the rest of the fingers, while the hallux (big toe) ranges between being perpendicular and pointing slightly backwards. I think this one is a big achievement for us. Cambodian Journal of Natural History 2011 , 104–133. There are five species of slow Loris: the Bengal, Bornean, Javan, pygmy and Sunda slow Loris. The genus Nycticebus is one of the least studied Asian primates. The last captive birth for these species in North America was in 2001 in San Diego. kayan—was also distinguished from the same. In Java, it was thought that putting a piece of its skull in a water jug would make a husband more docile and submissive, just like a slow loris in the daytime. 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). Its geographic range is larger than that of any other slow loris species. Before stashing their offspring in a secure location, female slow lorises will lick their brachial glands, and then groom their young with their toothcomb, depositing the toxin on their fur. [139] They are seen as a "living toy" for children by local people or are bought out of pity by Western tourists or expatriates. In the next morning they released that Loris in the Satchari National Park. ... [a slow loris's] life is not a happy one, for it is continually seeing ghosts; that is why it hides its face in its hands. [78], Slow lorises are found in South and Southeast Asia. [8][63] Their combined head and body lengths vary by species, but range from 18 to 38 cm (7.1 to 15.0 in) between all species. The combined brachial secretion and saliva of recently captured wild lorises was shown to contain batrachotoxins, which were not found in slow lorises held in captivity for more than a year. [124] In the province of North Sumatra, the slow loris is thought to bring good luck if it is buried under a house or a road. [87], Slow lorises range across tropical and subtropical regions[88] and are found in primary and secondary rainforests, as well as bamboo groves and mangrove forests. All four of these are expected to be listed with at least the same, if not a higher-risk, conservation status. [66] Slow lorises have monochromatic vision, meaning they see in shades of only one color. Bengal slow loris is facing habitat loss due to felling of roosting and feeding trees across its range. Slow loris saliva has been shown to be cytotoxic to human skin cells in laboratory experiments without the admix of BGE. Lorises are arboreal and nocturnal, curling up to sleep by day. The extent of planted forests has greatly increased in the tropics, but their conservation value while assumed to be low, is largely unknown. Pygmy slow lorises are doing better in North American zoos; from the late 1980s (when they were imported) to 2008, the population grew to 74 animals, with most of them born at the San Diego Zoo. Their range includes parts of South and Southeast Asia. Seconde Famille. Most are small, but an unnamed form dating to 15–16 mya is comparable in size to the largest living slow lorises. [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. [140][144] Without their teeth, the animals can no longer fend for themselves in the wild, and must remain in captivity for life. The Bengal slow loris was only recently recognised as a distinct species having been previously classed as a sub species of Nycticebus coucang.. The pygmy slow loris (N. pygmaeus) occurs east of the Mekong River in Yunnan, Laos, Vietnam, and Cambodia. This toxic bite is a rare trait among mammals and unique to lorisid primates. [63] Similar to the slender lorises, the fur around and directly above the eyes is dark. [18], 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. bengalensis that he had received two years earlier. In tests, three predators—binturongs, clouded leopards (Neofelis nebulosa), and sun bears—retreated or showed other signs of displeasure when presented with cotton swabs anointed with a mixture of the toxic secretion and the saliva, whereas the toxic secretion alone generated mild interest. [98] In Indonesia, slow lorises are called malu malu or "shy one" because they freeze and cover their face when spotted. 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 (N. bengalensis) has the largest distribution of all the slow lorises and can be found in Bangladesh, Cambodia, southern China, Northeast India, Laos, Burma, Thailand, and Vietnam. javanicus). They would almost get lost in your pencil case! "[126], Because of their "cuteness", videos of pet slow lorises are some of the most frequently watched animal-related viral videos on YouTube. They have a range of habitats over a vast area of southern and south-eastern Asia There are nine species of slow lorises currently recognised - the Bengal, Bornean, greater, Hiller's, Javan, Kayan, Philippine, pygmy and Sody's The slow loris is a nocturnal primate that has forward-facing eyes and human-like hands with an opposable thumb They based their decision on an analysis of cranial morphology and characteristics of pelage. The group's closest relatives are the slender lorises of southern India and Sri Lanka. [140] According to National Geographic, slow lorises are protected by both local laws in southern Asia and by the Convention on International Trade in Endangered Species (CITES). One new species has recently been discovered on Borneo. Bengal slow lorises are the largest of the species, weighing up to two kilograms. [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. It is known from 24 protected areas in Vietnam a… [17], American zoologist Dean Conant Worcester, describing the Bornean slow loris in 1891. [97], Due to their slow movement, all lorises, including the slow lorises, have a specially adapted mechanism for defense against predation. The Bengal slow loris is also the largest of the slow loris species, weighing between 1 and 2 kg and with a body length (head to tail) of 26 to 38 cm. The Bengal Slow Loris is listed as Vulnerable by the IUCN Red List of Threatened Species. It is thought all nine recognised species of this small-bodied nocturnal primate are venomous. All of the slow loris are under threat of wildlife business and habitat loss. IUCN Red List Status Vulnerable [33] 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. G. Rehn clarified in 1902 that Linnaeus's name actually referred to a slender loris. [74] The sturdy thumb helps to act like a clamp when digits three, four, and five grasp the opposite side of a tree branch. These little guys are under 10 inches long from head to tail, and weigh only 6 pounds. The smallest slow Lorises live in Borneo, an island in South East Asia. [140] Pet owners also fail to provide proper care because they are usually asleep when the nocturnal pet is awake.[129][144]. Population. Although most of the recognized lineages of Nycticebus (including N. pygmaeus, N. menagensis and N. javanicus) were shown to be genetically distinct—the analysis suggested that DNA sequences from some individuals of N. coucang and N. bengalensis apparently share a closer evolutionary relationship with each other than with members of their own species. ", "Letters from the Menage Scientific Expedition to the Philippine Islands", International Animal Rescue: Saving the slow loris, Dr. Anna Nekaris' research and conservation, Asian loris and African pottos conservation website directory, https://en.wikipedia.org/w/index.php?title=Slow_loris&oldid=995540678, Creative Commons Attribution-ShareAlike License, This page was last edited on 21 December 2020, at 16:31. [95] Due to their long gestations (about six months), small litter sizes, low birth weights, long weaning times (three to six months),[107] and long gaps between births, slow loris populations have one of the slowest growth rates among mammals of similar size. [46] The analyses published in 2006 by Chen and colleagues' proved inconclusive, although one test suggested that N. coucang and N. bengalensis apparently share a closer evolutionary relationship with each other than with members of their own species, possibly due to introgressive hybridization since the tested individuals of these two taxa originated from a region of sympatry in southern Thailand. What are they like? Scientific Name Nycticebus bengalensis. They also believe that slow lorises have medicinal powers because they require more than one hit with a stick to die. [122]. [61] The brains of slow lorises have more folds (convolutions) than the brains of galagos. The sublingua extends below the tip of the tongue and is tipped with keratinized, serrated points that rake between the front teeth. [45] Species differentiation was based largely on differences in morphology, such as size, fur color, and head markings. [108] Traditional medicine made from loris parts is thought to cure many diseases,[124] and the demand for this medicine from wealthy urban areas has replaced the subsistence hunting traditionally performed in poor rural areas. The bony palate (roof of the mouth) only goes as far back as the second molar. [19] The word "loris" was first used in 1765 by Buffon as a close equivalent to a Dutch name, loeris. Of the 29 captive specimens in North American zoos in 2008, several are hybrids that cannot breed, while most are past their reproductive years. "CITES Proposal Highlights Rarity of Asian Nocturnal Primates (Lorisidae: "A molecular phylogeny of living primates", "Indonesia's Slow Lorises Suffer in Trade", "Fossil evidence for an ancient divergence of lorises and galagos", "A collection of mammals from Sumatra, with a review of genera, "Note on the nomenclature of the Northern Slow-loris", "Distribution survey of Bengal Slow Loris, 10.1002/(SICI)1098-2345(1997)43:2<159::AID-AJP5>3.0.CO;2-W, "Fast food for slow lorises: is low metabolism related to secondary compounds in high-energy plant diet? More recently, researchers have documented the belief that the consumption of loris meat was an aphrodisiac that improves "male power". The slow lorises are a group of nocturnal strepsirrhine primates that inhabit the Southeast Asia and its neighboring areas. [110] The most common dietary item was nectar from flowers of the Bertram palm (Eugeissona tristis). Strepsirrhini", "Chapter 12: Talking Defensively, a Dual Use for the Brachial Gland Exudate of Slow and Pygmy Lorises". Slow lorises have a special network of blood vessels in their hands and feet, which makes them vulnerable to cuts when pulled from the wire cages they are kept in. Vocal exchanges and alarm calls are limited; scent marking with urine is the dominant form of communication. They would almost get lost in your pencil case! [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. Slow lorises are nocturnal strepsirrhine primates in the genus Nycticebus that live in the rainforests of South and Southeast Asia. [8] Their intermembral index (ratio of arm to leg length) averages 89, indicating that their forelimbs are slightly shorter than their hind limbs. The species is named ? [85] However, despite the lost habitat, their decline is most closely associated with unsustainable trade, either as exotic pets or for traditional medicine. Once disturbed, they immediately stop moving and remain motionless. The slow lorises inhabit tropical and subtropical climate regions where they inhabit rainforests, bamboo, and mangrove forests. Slow lorises have a toxic bite, a trait rare among mammals and unique among the primates. This species is mainly frugivorous (fruit eating) but also feeds on insects, gum, and small reptiles.
