A slow loris in its natural habitat. Habitat . Their exact … [59] Compared with the slender lorises, the snout of the slow loris is even less pointed. All slow lorises are threatened by the wildlife trade and habitat loss. 2008), is threatened in part by habitat loss and fragmentation, but it is becoming increasingly clear that in fact commercial wildlife trade poses the greatest threat. This etymology was later supported by the physician William Baird in the 1820s, who noted that the Dutch word loeris signified "a clown". Unlike the slender lorises, however, the white stripe that separates the eye rings broadens both on the tip of the nose and on the forehead while also fading out on the forehead. [62], The ears are small,[8] sparsely covered in hair, and hidden in the fur. It then has the ability to chemically-defend itself from predator, making itself unpalatable, and able to fend off predators with burning. [132] Furthermore, local trade is illegal because every nation in which they occur naturally has laws protecting them. Interesting Loris Facts: Size of the loris depends on the species. However, the IUCN still lists this species as Vulnerable to extinction. The species is listed as However, the fathers become hostile towards their male offspring after 12 to 14 months and will chase them away. Slow lorises move slowly and deliberately, making little or no noise, and when threatened, they stop moving and remain motionless. They can live to be 25 years old. Their eyes are large[22][65] and possess a reflective layer, called the tapetum lucidum, that improves low-light vision. It prefers rainforests with dense canopies, and its presence in its native habitat indicates a healthy ecosystem. They are omnivores, eating small animals, fruit, tree gum, and other vegetation. [103], Slow lorises produce a secretion from their brachial gland (a scent gland on the upper arm near the axilla) that is licked and mixed with their saliva. [140][144] Without their teeth, the animals can no longer fend for themselves in the wild, and must remain in captivity for life. Slow lorises have a toxic bite, a trait rare among mammals and unique among the primates. They pre­fer areas of high canopy cover and for­est edges, where in­sects are more abun­dant. … The species is listed as "Vulnerable" on the IUCN Red List, and is threatened with extinction due to a growing demand in the exotic pet trade and traditional medicine. The Bengal Slow Loris is listed as Vulnerable by the IUCN Red List of Threatened Species. One new species has recently been discovered on Borneo. The last captive birth for these species in North America was in 2001 in San Diego. Their range includes parts of South and Southeast Asia. [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. Once disturbed, they immediately stop moving and remain motionless. [97] To move between trees, they carefully grip the terminal branches of the neighboring tree and pull themselves across the small gap. [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. 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. The extent of planted forests has greatly increased in the tropics, but their conservation value while assumed to be low, is largely unknown. ======================================= Connectivity between protected areas is important for slow lorises because they are not adapted to dispersing across the ground over large distances. 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. Cambodian Journal of Natural History 2011 , 104–133. [110] The Sunda slow loris eats insects that other predators avoid due to their repugnant taste or smell. I think this one is a big achievement for us. An arboreal animal, the Bengal slow loris is found in almost all types of … [8] The strong grip can be held for hours without losing sensation due to the presence of a rete mirabile (network of capillaries), a trait shared among all lorises. [75][95] Vocalizations include an affiliative (friendly) call krik, and a louder call resembling a crow's caw. The BGE has several ecological functions including anti-parasitic defence and communication. To protect itself, the Slow loris has also been observed to rub the venom on its fur. [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. [6] It can also be found in bamboo groves. Bengal Slow Loris . Depending on the species, they live in both tropical regions with high rainfall, and subtropical regions with less rainfall. [99], If cornered, they may adopt a defensive posture by curling up and lunging at the predator. Their only documented predators—apart from humans—include snakes, changeable hawk-eagles and orangutans, although cats, viverrids and sun bears are suspected. They in­habit trop­i­cal and sub-trop­i­cal rain­forests as well as semi-ever­green rain­forests in south­east­ern Asia year round. Bengal slow lorises are the largest of all of the slow lorises, with a skull length of 65.25 mm, larger than any other species of loris. The group's closest relatives are the slender lorises of southern India and Sri Lanka. It is a seed disperser and pollinator, as well as a prey item for carnivores. The marks remaining after gouging can be used by field workers to assess loris presence in an area. [64], The eyes of slow lorises are forward-facing, which gives stereo vision. largest of the lorises, the Bengal slow loris Nycticebus bengalensis. [129] When they were all considered a single species, imprecise population data together with their regular occurrence in Southeast Asian animal markets combined to erroneously suggest that slow lorises were common. It is possible that this layer blurs the images they see, as the reflected light may interfere with the incoming light. [140] Pet owners also fail to provide proper care because they are usually asleep when the nocturnal pet is awake.[129][144]. Slow lorises reproduce slowly, and the infants are initially parked on branches or carried by either parent. [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. In the next morning they released that Loris in the Satchari National Park. Slow loris can range from heavy slow loris to 255 grams (1.5 oz), and 2.5 grams (o৪ oz) for Bengal slow loris. Females reach sexual maturity at 18 to 24 months, while males are capable of reproducing at 17 months. Photo Ark 24 Day Old Bengal Slow Loris. Slow loris venom was known in folklore in their host countries throughout southeast Asia for centuries, but dismissed by western scientists until the 1990s. Their toxic bite, once thought to be primarily a deterrent to predators, has been discovered to be primarily used in disputes within the species. [84] The Bornean slow loris (N. menagensis), found on Borneo and nearby islands, including the Sulu Archipelago,[82] and in 2012 was split into four distinct species (adding N. bancanus, N. borneanus, and N. Habitat. [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. [104] It may also be used for defense against other slow lorises and parasites. [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. 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. [92], Preliminary results of studies on the pygmy slow loris indicate that its diet consists primarily of gums and nectar (especially nectar from Saraca dives flowers), and that animal prey makes up 30–40% of its diet. Slow lorises also experience many health problems due to both local and international trade. This manifested as incorrect Red List assessments of "Least Concern" as recently as 2000. [34], Several more species were named around 1900, including Nycticebus menagensis (originally Lemur menagensis) by Richard Lydekker in 1893[35] and Nycticebus pygmaeus by John James Lewis Bonhote in 1907. Bengal slow lorises are the largest of the species, weighing up to two kilograms. By Prafulla Kaman. [21][22][23] This species was based on the "tailless maucauco" described by Thomas Pennant in 1781, which is thought to have been based on a Sunda slow loris, and on Vosmaer's description of a Bengal 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. =======================================, Why international students choose Oxford Brookes, Research integrity and responsible metrics, Research ethics (staff and students only), Policies and codes of practice (staff and students only), Knowledge exchange (staff and students only), Research impact (staff and students only), Help us protect the only poisonous primate, Modern slavery statement, Student Protection Plan, Lorises are small to medium-sized primates which range in weight from 103 g to 2100 g, 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, The name 'loris' is Dutch and means 'clown', which probably comes from the facial features that help to define the species, The slow loris are among the rarest primates on earth; they diverged from their closest cousins the African bushbabies around 40 million years ago, Although slow lorises are seen as slow movers, they frequently ’race walk’ and can move up to 8 km-per night. The sublingua extends below the tip of the tongue and is tipped with keratinized, serrated points that rake between the front teeth. [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. [113] It is not known how the sympatric pygmy and Bengal slow lorises partition their feeding niches. Even the best breeding facilities have great difficulty breeding lorises, and those that do often have difficulty keeping them alive. [134], Populations of Bengal and Sunda slow lorises are not faring well in zoos. [30][31][32] Geoffroy also named Nycticebus javanicus in this work. Slow lorises are nocturnal strepsirrhine primates in the genus Nycticebus that live in the rainforests of South and Southeast Asia. [105], Studies suggest that slow lorises are polygynandrous. [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. These little guys are under 10 inches long from head to tail, and weigh only 6 pounds. The genus Nycticebus is one of the least studied Asian primates. [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. [127], Primatologist Anna Nekaris, in 2009 discussing the misleading information posted on YouTube. [8] They are most closely related to the slender lorises of South Asia, followed by the angwantibos, pottos and false pottos of Central and West Africa. [110] The plant gums, obtained typically from species in the family Fabaceae (peas), are high in carbohydrates and lipids, and can serve as a year-around source of food, or an emergency reserve when other preferred food items are scarce. [63], Slow lorises have a powerful grasp with both their hands and feet due to several specializations. 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. In captivity, they can live 20 or more years. 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). [110][112] A more detailed study of another Sunda slow loris population in 2002 and 2003 showed different dietary proportions, consisting of 43.3% gum, 31.7% nectar, 22.5% fruit, and just 2.5% arthropods and other animal prey. The Bengal slow loris was only recently recognised as a distinct species having been previously classed as a sub species of Nycticebus coucang.. This toxic bite is a rare trait among mammals and unique to lorisid primates. [98] In Indonesia, slow lorises are called malu malu or "shy one" because they freeze and cover their face when spotted. [110][114] Slow lorises have been reported gouging for exudates at heights ranging from 1 m (3 ft 3 in) to as much as 12 m (39 ft); the gouging process, whereby the loris repetitively bangs its toothcomb into the hard bark, may be loud enough to be heard up to 10 m (33 ft) away. [117][118] Slow lorises can use both hands to eat while hanging upside down from a branch. [75] Copulation often occurs while suspended with the hands and feet clinging to horizontal branches for support. The slow loris has a bite so poisonous that its venom can kill. We are always there to serve the slow Loris. Slow lorises (genus Nycticebus) are strepsirrhine primates and are related to other living lorisoids, such as slender lorises (Loris), pottos (Perodicticus), false pottos (Pseudopotto), angwantibos (Arctocebus), and galagos (family Galagidae), and to the lemurs of Madagascar. Slow lorises are threatened by a combination of habitat loss and over-exploitation, and nowhere is this more apparent than in the wildlife markets of Cambodia, Indonesia, Myanmar and southern China. Slow lorises are a group of several species of nocturnal strepsirrhine primates that make up the genus Nycticebus. The bony palate (roof of the mouth) only goes as far back as the second molar. Both fluids have been demonstrated as being venomous individually and creating a more potent venom when mixed. The Bengal slow loris is a stickler for routine, always using the same routes to reach the same dining trees, a boon to the researcher during her fieldwork. [74] The sturdy thumb helps to act like a clamp when digits three, four, and five grasp the opposite side of a tree branch. Some species also live in agricultural areas, like plantations. [43], Slow lorises have a round head[57] because their skull is shorter than in other living strepsirrhine. [126] In order to give the impression that the primates are tame and appropriate pets for children,[144] to protect people from their potentially toxic bite,[133] or to deceive buyers into thinking the animal is a baby,[126] animal dealers either pull the front teeth with pliers or wire cutters or cut them off with nail cutters. [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. kayan—was also distinguished from the same. They also believe that slow lorises have medicinal powers because they require more than one hit with a stick to die. The first genus is Loris. It is found in parts of Yunnan and southwest Guangxi, China, and has been recorded in Bangladesh’s Chittagong Hill Tracts. [88] Slow lorises are also smuggled to China, Taiwan, Europe, Russia, the United States, and Saudi Arabia for use as pets. [94], Such a social system is distinguished by a lack of matriarchy and by factors that allow the slow loris to remain inconspicuous and minimize energy expenditure. [97], Due to their slow movement, all lorises, including the slow lorises, have a specially adapted mechanism for defense against predation. The animal inhabits both deciduous and evergreen forest habitats within its range. Bengal slow lorises are the largest of the species, weighing up to two kilograms. [124] Loris wine is a traditional Cambodian medicine supposed to alleviate the pain of childbirth, made from a mixture of loris bodies and rice wine. The species has the largest geographical range of all the slow loris species and is endemic to northeast India, Bangladesh and Indochina (Cambodia, Laos, Burma, Vietnam, South China and Thailand). To make contact with other individuals, they emit a single high-pitched rising tone, and females use a high whistle when in estrus. The name derives from the Ancient Greek: νύξ, romanized: (nyx), genitive form of νυκτός (nyktos, "night"), and κῆβος (kêbos, "monkey"). All four of these are expected to be listed with at least the same, if not a higher-risk, conservation status. There are five species of slow Loris: the Bengal, Bornean, Javan, pygmy and Sunda slow Loris. What are they like? [126] Slow lorises are also stress-sensitive and do not do well in captivity. The slow lorises inhabit tropical and subtropical climate regions where they inhabit rainforests, bamboo, and mangrove forests. [110] However, one 2002 analysis of pygmy slow loris feces indicated that it contained 98% insect remains and just 2% plant remains. Cambodian Journal of Natural History 2011, 104–133. Bengal slow loris is facing habitat loss due to felling of roosting and feeding trees across its range. Their movement looks similar to that of a snake due to their twisting movement caused by having several more vertebra in their spine than other primates, The slow loris has a reduced second finger for gripping and one of the longest tongues of all the primates, which they use to drink nectar, Although the slow loris is a small mammal, their home ranges can be the size of 35 football pitches, The slow loris has a bite so poisonous that its venom can kill. Of the 29 captive specimens in North American zoos in 2008, several are hybrids that cannot breed, while most are past their reproductive years. Rovero, F., Mtui, A., Kitegile, A., Jacob, P., Araldi, A., and Tenan, S. (2015). Share. [8] Their intermembral index (ratio of arm to leg length) averages 89, indicating that their forelimbs are slightly shorter than their hind limbs. [75][94] Adult males are highly territorial and are aggressive towards other males. [131], Since 2007, all slow loris species have been protected from commercial international trade under Appendix I of CITES. Neither local nor foreign buyers usually know anything about these primates, their endangered status, or that the trade is illegal. 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. The slow loris can live in many types of vegetation from bamboo to suburban gardens. Their collective range stretches from Northeast India through Indochina, east to the Sulu Archipelago (the small, southern islands of the Philippines), and south to the island of Java (including Borneo, Sumatra, and many small nearby islands). Loris, any of about 10 species of tailless or short-tailed South and Southeast Asian forest primates. The Bengal slow loris is the largest of the slow loris species, with considerable variation of size, and coat colour. The secretion from the arm contains a chemical related to cat allergen, but may be augmented by secondary toxins from the diet in wild individuals. Jhum cultivation, expansion of tea estates and the conversion of forests for agricultural uses are endangering the animal. [124] The following passage from an early textbook about primates is indicative of the superstitions associated with slow lorises: Many strange powers are attributed to this animal by the natives of the countries it inhabits; there is hardly an event in life to man, woman or child, or even domestic animals, that may not be influenced for better or worse by the Slow Loris, alive or dead, or by any separate part of it, and apparently one cannot usually tell at the time, that one is under supernatural power. 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. [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. The venom is administered through morphologically distinct dentition in the form of an adapted toothcomb. [74] Like nearly all lemuriforms, they have a grooming claw on the second toe of each foot. Bornean slow loris is the smallest species; it weighs only 9 to 11 ounces. ... [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. Currently there is no known cure. Currently there is no known cure. [124][132] Surveys are needed to determine existing population densities and habitat viability for all species of slow loris. [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 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. [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. [74], Unlike galagos, which have longer legs than arms, slow lorises have arms and legs of nearly equal length. The Bengal slow loris is nocturnal and arboreal, occurring in both evergreen and deciduous forests. [25][26] The next slow loris species to be described was Lori bengalensis (currently Nycticebus bengalensis), named by Bernard Germain de Lacépède in 1800. [96] When disturbed, slow lorises can also produce a low buzzing hiss or growl. Jhum cultivation, expansion of tea estates and the conversion of forests for agricultural uses are endangering the animal. [130], Slow lorises are sold locally at street markets, but are also sold internationally over the Internet and in pet stores. ", "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. Figure:Rescued Bengal Slow Loris. With this division of its range and population, the Bornean slow loris and the three new species face a higher risk of extinction than before. [106] Infants are either parked on branches while their parents find food or else are carried by one of the parents. [57] As with other members of Lorisidae, its interorbital distance is shorter than in lemurs. [72] Slow lorises have stout bodies,[63] and their tails are only stubs and hidden beneath the dense fur. The smallest slow Lorises live in Borneo, an island in South East Asia. Bengal slow lorises are the largest of the species, weighing up to two kilograms. Creature Profile. In the next morning they released that Loris in the Satchari National Park. [136] As many as 95% of the slow lorises rescued from the markets die of dental infection or improper care. Its geographic range is larger than that of any other slow loris species. [45] Species differentiation was based largely on differences in morphology, such as size, fur color, and head markings. Jan 16, 2020 - Geographic Distribution and Habitat The Bengal slow loris is a native of southeastern Asia, residing in the countries of Bangladesh, Cambodia, Vietnam, Lao … [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. Scientific Name Nycticebus bengalensis. The species is facing habitat loss and hunting pressures across its range. Bengal Slow Loris – Bengal slow Lorises have a relatively extensive range, and their populations live throughout Southeast Asia. [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. To find out more and learn how to disable these cookies, please see our cookies policy. [92] They spend about 20% of their nightly activities feeding.[119]. [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. These prosimians (the oldest, most “primitive” order of primates) are typically found in tropical, subtropical, evergreen, and semi-evergreen forests. [121] Slow lorises (of the genus Nycticebus) are accepted as the only known venomous primate. Slow lorises have one of the slowest primate life histories; six months pregnancy for these pint-sized primates produces babies the weight of a handful of paperclips (less than 50 g). [110] The most common dietary item was nectar from flowers of the Bertram palm (Eugeissona tristis). 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 prefers rainforests with dense canopies, and its presence in its native habitat indicates a healthy ecosystem. It is the only nocturnal primate found in northeastern India, which includes Assam, Mizoram, Nagaland, Meghalaya, Manipur and Tripura. [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. [78], Slow lorises are found in South and Southeast Asia. The extent of planted forests has greatly increased in the tropics, but their conservation value while assumed to be low, is largely unknown. Their habitat is rapidly disappearing and becoming fragmented, making it nearly impossible for slow lorises to disperse between forest fragments; unsustainable demand from the exotic pet trade and from traditional medicine has been the greatest cause for their decline.
