"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". The Sunda slow loris or greater slow loris is a strepsirrhine primate and a species of slow loris native to Indonesia, West Malaysia, southern Thailand and Singapore. Let us take a look at some interesting information about this animal, and its prospects as a pet. 75 [113] It is not known how the sympatric pygmy and Bengal slow lorises partition their feeding niches. [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. There are five total known species of slow loris (if pygmaeous are considered to be a separate species). [74] The sturdy thumb helps to act like a clamp when digits three, four, and five grasp the opposite side of a tree branch. Vertebrata – vertebrado, vertébrés, vertebrates. Is it Wise to Keep Crows as Pets? [98] The Acehnese name, buah angin ("wind monkey"), refers to their ability to "fleetingly but silently escape". The wounds caused by slow loris bites take some time to heal and may sometimes develop infection too. The species thrives in primary and secondary lowland forests that, unfragmented, allow them plenty of lush jungle in which to forage. This genus includes slow lorises and pygmy lorises. ycticebusBoddaert 1785 comprised two species, the pygmy loris (N. pyg- maeus) and the polytypic slow loris (N. coucang), which consisted of four subspecies [Groves, 1971]. [6][7] Lorisoids are thought to have evolved in Africa, where most living species occur;[9][10] later, one group may have migrated to Asia and evolved into the slender and slow lorises of today. Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. [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. It seems probable that there are more species (in the sense of sharply diagnosable entities) than hitherto recognized among small Asian primates, and contrasting to some degree with larger-sized taxa. Check Out Pet Care Plus. Once disturbed, they immediately stop moving and remain motionless. Bornean Loris Taxonomy / 47 Until recently, the genus N. ycticebus Boddaert 1785 comprised two species, the pygmy loris (N. pyg-maeus) and the polytypic slow loris (N. coucang), which consisted of four subspecies [Groves, 1971]. Only in 1998 was one of the subspecies ofN. [8][63] This gives their hands and feet a pincer-like appearance. [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. [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 first mandibular premolar is elongated, and the last molar has three cusps on the crown, the shortest of which is near the back. [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. Lorises are in the latter subfamily. These animals are believed to be the only poisonous primate in the world. This presumably relates to their lesser vagility and consequent reduced potential for gene-flow. [52][53] With that, the N. menagensis species complex that had been collectively known as the Bornean slow loris became four species: the Philippine slow loris (N. menagensis),[54] the Bornean slow loris (N. borneanus),[55] the Bangka slow loris (N. bancanus),[56] and the Kayan River slow loris (N. [44] 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. 75 They have been hunted by humans, for a long time and now, only a few are left in the wild. [83][100][130] The three newest species are yet to be evaluated by the IUCN, although each were once thought to be subpopulations of the Bornean slow loris—which was evaluated as "Vulnerable" in 2008. [92] They spend about 20% of their nightly activities feeding.[119]. [8] Their intermembral index (ratio of arm to leg length) averages 89, indicating that their forelimbs are slightly shorter than their hind limbs. [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. Three loris species occur in Asia: slow loris (Nycticebus coucang), pygmy loris (Nycticebus pygmaeus) and slender loris (Loris … In 1812, Étienne Geoffroy Saint-Hilaire named the genus Nycticebus, naming it for its nocturnal behavior. They are Sunda slow loris (Nycticebus coucang), pygmy slow loris (Nycticebus pygmaeus), Bengal slow loris (Nycticebus bengalensis), Bornean slow loris (Nycticebus menagensis) and Javan slow loris (Nycticebus javanicus). Parent: Lorinae [Taxonomy: Rank: genus (မျိုးစု အဖြစ် ပြသသည်) : Link: Slow loris|Nycticebus(Slow loris သို့ ချိတ်ဆက်ထားသည်) : Extinct: no Always displayed: yes (major rank) Taxonomic references: – Parent's taxonomic references: No. [30][31][32] Geoffroy also named Nycticebus javanicus in this work. (Identification key for slow lorises: in preparation) Click here for a larger figure. [91][92] Individuals sleep during the day, usually alone but occasionally with other slow lorises. The description was based on a male specimen sent to him by J. Vassal, a French physician who had collected the specimen from Nha Trang, Vietnam (then called Annam, a French Protectorate) in 1905. Vosmaer gave it the French name "le paresseux pentadactyle du Bengale" ("the five-fingered sloth of Bengal"), but Boddaert later argued that it was more closely aligned with the lorises of Ceylon (now Sri Lanka) and Bengal. When they feel threatened, slow lorises raise their hands above their head. This stripe extends to the tip of the snout on one end and the other end lies on the forehead. [96] When disturbed, slow lorises can also produce a low buzzing hiss or growl. It occurs in a variety of forest habitats, including tropical dry forests, semi-evergreen, and evergreen forests. [131], Since 2007, all slow loris species have been protected from commercial international trade under Appendix I of CITES. [123] In the late 19th and early 20th centuries, it was reported that the people from the interior of Borneo believed that slow lorises were the gatekeepers for the heavens and that each person had a personal slow loris waiting for them in the afterlife. 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. [8] They will also grip branches with only their hind feet, lift themselves upright, and quickly launch forward with their hands to catch prey. The species is named ? Lorisoids are thought to have evolved in Africa, where most living species occur; later, one group may h… 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. A suite of additional effects of the venom have been documented including ranging from mild to permanent disfigurement and mobility loss and near-death. [70][71], Slow lorises have relatively large maxillary canine teeth, their inner (mesial) maxillary incisors are larger than the outer (distal) maxillary incisors, and they have a diastema (gap) between the canine and the first premolar. For slow loris, there is no special season for breeding and the gestation period is around 190 days. The secretion from the brachial gland of captive slow lorises is similar to the allergen in cat dander, hence the secretions may merely elicit an allergic reaction, not toxicosis. It measures 27 to 38 cm from head to tail and weighs between 599 and 685 g. Like other slow lorises, it has a wet nose, a round head, small ears hidden in thick fur, a flat face, large eyes and a vestigial tail. The BGE has several ecological functions including anti-parasitic defence and communication. It seems probable that there are more species (in the sense of sharply diagnosable entities) than hitherto recognized among small Asian primates, and contrasting to some degree with larger-sized taxa. [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. They are less closely related to the remaining lorisoids (the various types of galago), and more distantly to the lemurs of Madagascar. [17], American zoologist Dean Conant Worcester, describing the Bornean slow loris in 1891. The Philippine slow loris (Nycticebus mengensis) lives along the northern and eastern coasts of Borneo and on the Philippine islands of Tawi-Tawi, Bongao, and Sanga-Sanga. [104] It may also be used for defense against other slow lorises and parasites. Slow loris saliva has been shown to be cytotoxic to human skin cells in laboratory experiments without the admix of BGE. [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. Beliefs about slow lorises and their use in traditional practices are deep-rooted and go back at least 300 years, if not earlier based on oral traditions. However, they can impart toxic bites, which can cause immense pain and may also lead to infection. Would you like to write for us? It lives together in small … The pygmy slow loris is a species of slow loris found east of the Mekong River in Vietnam, Laos, eastern Cambodia, and China. No. Strepsirrhini", "Chapter 12: Talking Defensively, a Dual Use for the Brachial Gland Exudate of Slow and Pygmy Lorises". [5] The toxin is obtained by licking a sweat gland on their arm, and the secretion is activated by mixing with saliva. Of the 29 captive specimens in North American zoos in 2008, several are hybrids that cannot breed, while most are past their reproductive years. [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. Other species of slow loris include : Unexpected diversity within the Javan slow loris trade: implications for slow loris taxonomy. Museum specimens of this animal had previously been identified as the Bornean slow loris (Nycticebus menagensis), first described by the English naturalist Richard Lydekker in 1893 as Lemur menagensis. 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. Secondary toxins may be introduced from the consumption of wild food, augmenting the toxicity. During daytime, these animals curl like balls and sleep on the branches of trees. [125], In the Mondulkiri Province of Cambodia, hunters believe that lorises can heal their own broken bones immediately after falling from a branch so that they can climb back up the tree. [140][144] Without their teeth, the animals can no longer fend for themselves in the wild, and must remain in captivity for life. [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. However, in 1939 Reginald Innes Pocock consolidated all slow lorises into a single species, N. coucang, and in his influential 1953 book … [110] The Sunda slow loris eats insects that other predators avoid due to their repugnant taste or smell. Disclaimer: ITIS taxonomy is based on the latest scientific consensus available, and is provided as a general reference source for interested parties. [22] A distinguishing feature of the slow loris skull is that the occipital bone is flattened and faces backward. The pygmy slow loris was first described scientifically by J. Lewis Bonhote in 1907. Due to the morphological similarity of Nycticebus spp. [83], There are currently eight recognized species. Taxonomy of the Bornean Slow Loris, with New Species Nycticebus kayan (Primates, Lorisidae) Journal/Book Name, Vol. History, taxonomy, and phylogeny. This manifested as incorrect Red List assessments of "Least Concern" as recently as 2000. We'll assume you're ok with this, but you can opt-out if you wish. Phylum. Nekaris KAI, Jaffe S. 2007. : American Journal of Primatology, vol. Slow lorises have their teeth cut or pulled out for the pet trade. But, before that, it is advisable to know more about some basic facts about this animal. [92][110][111] A 1984 study of the Sunda slow loris indicated that its diet consists of 71% fruit and gums, and 29% insects and other animal prey. Slow lorises move slowly and deliberately, making little or no noise, and when threatened, they stop moving and remain motionless. The lifespan of these animals is said to be around twenty years in captivity. We provide informative articles about caring for pets that you can come back to again and again when you have questions or want to learn more! This website uses cookies to improve your experience. Vocal exchanges and alarm calls are limited; scent marking with urine is the dominant form of communication. The bony palate (roof of the mouth) only goes as far back as the second molar. [129], Until the 1960s, the hunting of slow lorises was sustainable,[128] but due to growing demand, decreased supply, and the subsequent increased value of the marketed wildlife, slow lorises have been overexploited and are in decline. The three newest species are yet to be evaluated, but they arise from (and further reduce the ranks of) what was thought to be a single "vulnerable" species. Even where some gene-flow can be demonstrated, as betweenNycticebus coucang andN. [129] Infection, stress, pneumonia, and poor nutrition lead to high death rates among pet lorises. The pygmaeous slow loris is considered by some to be a member of the coucang species, but there is still debate (see Venom). [47] This hypothesis was corroborated by a 2007 study that compared the variations in mitochondrial DNA sequences between N. bengalensis and N. coucang, and suggested that there has been gene flow between the two species. [134], Populations of Bengal and Sunda slow lorises are not faring well in zoos. The slow loris is a small furry forest baby with big anime eyes, teddy … Recent incidents involving illegal primate trade in Taiwan. [15] Molecular clock analysis suggests that slow lorises may have started evolving into distinct species about 10 mya. : American Journal of Primatology, vol. Small-sized primates with a body weight of 200 grams to 2 kilograms. [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). Due in part to the large eyes that are an adaptation to their nocturnal lifestyle, they have also been popularized as 'cute' pets in viral videos on YouTube. [127], Primatologist Anna Nekaris, in 2009 discussing the misleading information posted on YouTube. [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. Apart from that, being an animal enlisted in the endangered species list, trading of slow loris or keeping them as pets is illegal in many countries. Slow lorises also experience many health problems due to both local and international trade. Subphylum. We also use third-party cookies that help us analyze and understand how you use this website. [78], Slow lorises are found in South and Southeast Asia. ... Taxonomy, distribution and status of the lesser slow loris Nycticebus pygmaeus and their implications for captive management. [38] In 1971 Colin Groves recognized the pygmy slow loris (N. pygmaeus) as a separate species,[39] and divided N. coucang into four subspecies,[40] while in 2001 Groves opined there were three species (N. coucang, N. pygmaeus, and N. bengalensis), and that N. coucang had three subspecies (Nycticebus coucang coucang, N. c. menagensis, and N. c. [135][136] They are especially popular or trendy in Japan, particularly among women. Taxonomy and phylogeny. [127] Slow lorises have lost a significant amount of habitat,[128] with habitat fragmentation isolating small populations and obstructing biological dispersal. [65][138][140] This results in severe bleeding, which sometimes causes shock or death. Sign up to receive the latest and greatest articles from our site automatically each week (give or take)...right to your inbox. [91] Home ranges of adults may significantly overlap, and those of males are generally larger than those of females. Likewise, gestation lasts 185 to 197 days, and the young weigh between 30 and 60 grams (1.1 and 2.1 oz) at birth. They have small snouts and even the ears are tiny. [121] Slow lorises (of the genus Nycticebus) are accepted as the only known venomous primate. The young ones reach sexual maturity at an age of eighteen to twenty months. [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. Their arms and legs are nearly equal in length, and their torso is long and flexible, allowing them to twist and extend to nearby branches. Illegal trafficking of this animal is one of the most common reasons for its dwindling population and so don’t encourage anybody to adopt these animals as pets. This is the reason why slow lorises that are used for pet trade have their teeth pulled out. N. bancanus is a strepsirrhine primate, and species of slow loris (genus Nycticebus) within the family Lorisidae. It is thought all nine recognised species of this small-bodied nocturnal primate are venomous. [136] As many as 95% of the slow lorises rescued from the markets die of dental infection or improper care. Lorises are primates of the suborder Prosimii and belong to the family Lorisidae.Lorisidae are divided into two subfamilies: Galaginae and Lorisinae.Lorises are in the latter subfamily. Geographic Range. 75 [60] The skull has prominent crests (ridges of bone). Neither local nor foreign buyers usually know anything about these primates, their endangered status, or that the trade is illegal. [43], Slow lorises have a round head[57] because their skull is shorter than in other living strepsirrhine. [116] Several anatomical adaptations present in slow lorises may enhance their ability to feed on exudates: a long narrow tongue to make it easier to reach gum stashed in cracks and crevices, a large cecum to help the animal digest complex carbohydrates, and a short duodenum to help quickly pass potentially toxic exudates. Documented predators include snakes, the changeable hawk-eagle (Nisaetus cirrhatus),[101] and Sumatran orangutans (Pongo abelii). N. kayan is a strepsirrhine primate and a species of slow loris (known collectively as the genus Nycticebus), within the loris family (Lorisidae). [122]. pygmaeus. [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. [130], Slow lorises are sold locally at street markets, but are also sold internationally over the Internet and in pet stores. Let the animal live peacefully in their natural habitat. Copyright © Pet Ponder & Buzzle.com, Inc. Phipps M. 1992. In the light of this taxonomy, all Sundaland slow lorises, previously considered Least Threatened, have been listed as Vulnerable or Endangered. This animal with a round face have eyes that are large and bulging. [47] Previous molecular analyses using karyotypes,[48] restriction enzymes,[49] and DNA sequences[50] were focused on understanding the relationships between a few species, not the phylogeny of the entire genus. [144], As part of the trade, infants are pulled prematurely from their parents, leaving them unable to remove their own urine, feces, and oily skin secretions from their fur. 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. Apart from their use in traditional medicine and pet trade, habitat loss is another factor that has contributed to their dwindling population. Since they consume a relatively high-calorie diet that is available year-round, it has been proposed that this slow metabolism is due primarily to the need to eliminate toxic compounds from their food. The parents carry the young ones and take care of them till they get weaned (takes up to six months). [27][28], In 1812, Étienne Geoffroy Saint-Hilaire named the genus Nycticebus,[29] naming it for its nocturnal behavior. [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. Seconde Famille. Taxonomy of the Bornean Slow Loris, with New Species Nycticebus kayan (Primates, Lorisidae) Journal/Book Name, Vol. 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. They based their decision on an analysis of cranial morphology and characteristics of pelage. kayan). In short, slow loris is an animal that is facing extinction and so, it is better to avoid keeping them as pets. [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. The pygmaeous slow loris is considered by some to be a member of the coucang species, but there is still debate (see Venom). 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. All of the members of Nycticebus are venomous. [74] Like nearly all lemuriforms, they have a grooming claw on the second toe of each foot. Their only documented predators—apart from humans—include snakes, changeable hawk-eagles and orangutans, although cats, viverrids and sun bears are suspected. Contributions to Zoology 76 (3): 187-196. [25][26] The next slow loris species to be described was Lori bengalensis (currently Nycticebus bengalensis), named by Bernard Germain de Lacépède in 1800. [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. Most are small, but an unnamed form dating to 15–16 mya is comparable in size to the largest living slow lorises. They are usually not found in groups and males are quite aggressive and territorial. A seven-year study of captive-bred pygmy slow lorises showed a skewed sex distribution, with 1.68 males born for every 1 female. 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. The lorisidae family includes African pottos and angwantibos and the Asian lorises. Infraphylum. [8][74], Slow lorises have an unusually low basal metabolic rate, about 40% of the typical value for placental mammals of their size, comparable to that of sloths. It is also said that they deliver the toxins not with their sharp canines, but with the small teeth located in front of the lower jaw. [97] To move between trees, they carefully grip the terminal branches of the neighboring tree and pull themselves across the small gap. [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. kayan). [13] The Thai record is based on a single tooth that most closely resembles living slow lorises and that is tentatively classified as a species of Nycticebus. [85] However, despite the lost habitat, their decline is most closely associated with unsustainable trade, either as exotic pets or for traditional medicine. Though, slow lorises are cute and small, they can impart toxic bites. These cookies will be stored in your browser only with your consent. They are small-sized primates that are found in southeast Asian countries like Indonesia, Thailand, Borneo, Philippines and Vietnam. [97], Due to their slow movement, all lorises, including the slow lorises, have a specially adapted mechanism for defense against predation. The venom is administered through morphologically distinct dentition in the form of an adapted toothcomb. [99], If cornered, they may adopt a defensive posture by curling up and lunging at the predator. [102] Other potential predators include cats, sun bears (Helarctos malayanus), binturongs (Arctictis binturong), and Asian palm civets. [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. It is mandatory to procure user consent prior to running these cookies on your website. Prior to 2013, museum specimens of this animal had been identified as the Bornean slow loris (Nycticebus menagensis), which had first been described by the English naturalist Richard Lydekker in 1893 as Lemur menagensis. In that way, a slow loris can be ideal as a pet. Females reach sexual maturity at 18 to 24 months, while males are capable of reproducing at 17 months. [75][95] Vocalizations include an affiliative (friendly) call krik, and a louder call resembling a crow's caw. 6789 Quail Hill Pkwy, Suite 211 Irvine CA 92603. Hence slow lorises are said to be related to pottos, angwantibos and galagos of Africa. [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. While pygmy slow lorises are the smallest species, the largest ones are Bengal slow lorises. The next slow loris species to be described was Lori bengalensis (currently Nycticebus bengalensis), named by Bernard Germain de Lacépède in 1800. The tail is also stumpy and is mostly kept close to the body. 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. Gnathostomata. [8][57][76] Both slender and slow lorises have relatively short feet. [124][132] Surveys are needed to determine existing population densities and habitat viability for all species of slow loris.
