cades, sightings of the slow loris have increased remarkably, and these have coincided with an increase in nocturnal surveys. Sunda slow loris or greater slow loris (Nycticebus coucang) inhabits the rainforests of Indonesia, including Sumatra, Malaysia, Thailand and Singapore. Slow lorises are one of only six mammal species known to be venomous. Photo courtesy Rainforest Rescue Endangered Species Spotlight: Slow Loris . The pygmy slow loris (Nycticebus pygmaeus) is a species of slow loris found east of the Mekong River in Vietnam, Laos, eastern Cambodia, and China.It occurs in a variety of forest habitats, including tropical dry forests, semi-evergreen, and evergreen forests.The animal is nocturnal and arboreal, crawling along branches using slow movements in search of prey. [74] Like nearly all lemuriforms, they have a grooming claw on the second toe of each foot. The pattern of stripes of its facial markings and the highly contrasting black and white features of its face helps to distinguish the Kayan River slow loris from other slow lorises. The Javan slow loris (Nycticebus javanicus) is one of nine extant species of slow loris and is found on the Indonesian island of the same name. [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. A suite of additional effects of the venom have been documented including ranging from mild to permanent disfigurement and mobility loss and near-death. There are 10 different species of Lorises, which researchers divide into 2 genuses. [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. [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. This is a small and highly specific suborder of primates native to one part of the world. Rain Forest Canopy Bridges Aid Slow Lorises, Gibbons and Other Threatened Species. Slow Loris . Bengal slow loris is facing habitat loss due to felling of roosting and feeding trees across its range. How Many Species Of Lynx Live In The World Today? Slow lorises are nocturnal and arboreal, or tree-dwelling, primates. It is thought all nine recognised species of this small-bodied nocturnal primate are venomous. Slow lorises have their teeth cut or pulled out for the pet trade. 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. studied wounding patterns and aggressive behaviours in a venomous mammal — the Javan slow loris — in the wild. indicates the tentative nature of the assignment). Connectivity between protected areas is important for slow lorises because they are not adapted to dispersing across the ground over large distances. [108] Pygmy slow lorises are likely to give birth to twins—from 50% to 100% of births, depending on the study; in contrast, this phenomenon is rare (3% occurrence) in Bengal slow lorises. [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. … Common health problems seen in pet slow lorises include undernourishment, tooth decay, diabetes, obesity, and kidney failure. [135][136] They are especially popular or trendy in Japan, particularly among women. The chemical composition of the toxin secreted by this slow loris species is different from those of the other species. [25][26] The next slow loris species to be described was Lori bengalensis (currently Nycticebus bengalensis), named by Bernard Germain de Lacépède in 1800. [97] To move between trees, they carefully grip the terminal branches of the neighboring tree and pull themselves across the small gap. Their next closest relatives are the African lorisids, the pottos, false pottos, and angwantibos. [27][28], In 1812, Étienne Geoffroy Saint-Hilaire named the genus Nycticebus,[29] naming it for its nocturnal behavior. [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. [78], Slow lorises are found in South and Southeast Asia. [45] Species differentiation was based largely on differences in morphology, such as size, fur color, and head markings. [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. [130] With the use of modern technology, such as battery-powered search lights, slow lorises have become easier to hunt because of their eye shine. [139] They are seen as a "living toy" for children by local people or are bought out of pity by Western tourists or expatriates. All slow loris species are protected by international laws and listed on CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) Appendix 1, which means that all trade is illegal. [62], The ears are small,[8] sparsely covered in hair, and hidden in the fur. Most members of this genus are all commonly referred to as a slow loris. [131], Since 2007, all slow loris species have been protected from commercial international trade under Appendix I of CITES. What are they like? The animal inhabits both deciduous and evergreen forest habitats within its range. [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. [140] Pet owners also fail to provide proper care because they are usually asleep when the nocturnal pet is awake.[129][144]. [5] The toxin is obtained by licking a sweat gland on their arm, and the secretion is activated by mixing with saliva. Slow loris is a group of several species of nocturnal strepsirhine primates that produce the genus Nichtisbus. Slender lorises feed mostly on insects (predominantly ants) and are solitary. [126][135] The reasons for their popularity, according to the Japan Wildlife Conservation Society, are that "they're easy to keep, they don't cry, they're small, and just very cute. When threatened, slow lorises may also lick their brachial glands and bite their aggressors, delivering the toxin into the wounds. [98] In Indonesia, slow lorises are called malu malu or "shy one" because they freeze and cover their face when spotted. It also has the largest size. 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. Males are highly territorial. 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. How Many Types Of Leopards Live In The World Today? 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… The species’ diet includes insects, nectar, fruits, etc. CURRENT RANGE: Tropical evergreen rainforests across Southeast Asia CURRENT THREATS: Deforestation and the illegal animal trade CONSERVATION STATUS: Endangered WHERE YOU CAN SEE THEM: In Southern Asia (from India east to China and the Philippines) and zoos all over the … [52] The Javan slow loris (N. javanicus) is only found on the island of Java in Indonesia. Lemuriens. [59] Compared with the slender lorises, the snout of the slow loris is even less pointed. The Nycticebus genus contains slow Lorises, of which there are 8 species. It is thus classified as a “Critically Endangered” species by the IUCN. kayan). [63], Slow lorises have a powerful grasp with both their hands and feet due to several specializations. [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. The gall bladder of the Bengal slow loris has historically been used to make ink for tattoos by the village elders in Pursat and Koh Kong Provinces of Cambodia. The international trafficking of slow lorises began when 18th-century Dutch explorers brought home lorises from their voyages to southeast Asia. Slow lorises reproduce slowly, and the infants are initially parked on branches or carried by either parent. In captivity, they can live 20 or more years. The animal is identified by its crimson-red colored fur on the back and light-colored features on the face. Rachel Munds, Anna Nekaris and Susan Ford based these taxonomic revisions on distinguishable facial markings. Their eyes are large[22][65] and possess a reflective layer, called the tapetum lucidum, that improves low-light vision. [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. [138], International trade usually causes a high mortality rate during transit, between 30% and 90%. 1. The International Union for Conservation of Nature (IUCN) has classified Sunda slow loris as a vulnerable species. Nekaris et al. The pygmy slow loris (Nycticebus pygmaeus) is a species of slow loris found east of the Mekong River in Vietnam, Laos, eastern Cambodia, and China. In the wild, envenomation occurs from intraspecific competition; whereby two slow lorises fight for mates, food or territory. It then has the ability to chemically-defend itself from predator, making itself unpalatable, and able to fend off predators with burning. The dark, contrasting facial features and unique markings on the face help to distinguish this species of slow loris. [102] Other potential predators include cats, sun bears (Helarctos malayanus), binturongs (Arctictis binturong), and Asian palm civets. It has thick, fur, brown-gray wool on the back and white wool beneath it. The Javan slow loris is also an omnivore and feeds on eggs, lizards, fruit, tree gum, etc. [126] Slow lorises are also stress-sensitive and do not do well in captivity. [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. "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 animals start to feed around sunset and have an omnivorous diet. Their evolutionary history is uncertain since their fossil record is patchy and molecular clock studies have given inconsistent results. 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. [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. [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. With high wounding rates in more than 20% of the population and extreme territoriality, loris venom is an unusual case of venom functioning as a weapon in intraspecific competition used for resource and mate defence. [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. They move with slow, deliberate hand-over-hand movements … through the trees but can move quickly if necessary. Strepsirrhini", "Chapter 12: Talking Defensively, a Dual Use for the Brachial Gland Exudate of Slow and Pygmy Lorises". [117][118] Slow lorises can use both hands to eat while hanging upside down from a branch. [110] The Sunda slow loris eats insects that other predators avoid due to their repugnant taste or smell. The Javan slow loris (Nycticebus javanicus) is one of nine extant species of slow loris and is found on the Indonesian island of the same name. [127], Primatologist Anna Nekaris, in 2009 discussing the misleading information posted on YouTube. Their eye rings are separated by a white stripe and their lips and noses are covered by moist skin. [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. [110] The most common dietary item was nectar from flowers of the Bertram palm (Eugeissona tristis). [8][63] This gives their hands and feet a pincer-like appearance. Slow lorises are a group of several species of nocturnal strepsirrhine primates that make up the genus Nycticebus. The first mandibular premolar is elongated, and the last molar has three cusps on the crown, the shortest of which is near the back. Buyers rarely have any concern about what variety of slow loris they are receiving. 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. Photograph by Ch'ien C. Lee New slow loris species has "striking" eye patches, toxic bite. 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. 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. [63] As with the slender lorises, their arms are slightly longer than their body,[74] but the extremities of slow lorises are more stout. Once disturbed, they immediately stop moving and remain motionless. 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. Slow lorises are nocturnal and live in trees in various types of forest. [19] The word "loris" was first used in 1765 by Buffon as a close equivalent to a Dutch name, loeris. [136] As many as 95% of the slow lorises rescued from the markets die of dental infection or improper care. How Many Types Of Camels Live In The World Today. The BGE has several ecological functions including anti-parasitic defence and communication. [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. Lorises are not immune to their own species' venom. To protect itself, the Slow loris has also been observed to rub the venom on its fur. [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. Diet and Behavior Food Choices. The animal measures about 293 mm from head to tail. Learn about the most threatened Lorises below. [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. [98] The Acehnese name, buah angin ("wind monkey"), refers to their ability to "fleetingly but silently escape". [8][57][76] Both slender and slow lorises have relatively short feet. While the lorises in these videos may appear fine, they are actually suffering — as is the entire species. The slow lorises are either small or medium-sized with length ranging from 18 to 38 cm. [46], To help clarify species and subspecies boundaries, and to establish whether morphology-based classifications were consistent with evolutionary relationships, the phylogenetic relationships within the genus Nycticebus were investigated by Chen and colleagues using DNA sequences derived from the mitochondrial markers D-loop and cytochrome b. This etymology was later supported by the physician William Baird in the 1820s, who noted that the Dutch word loeris signified "a clown". It is usually a solitary creature but occasionally resides in small groups. 7. The Nycticebus bengalensis or the Bengal slow loris is a slow loris species that is native to Indochina and the Indian subcontinent. [97], Due to their slow movement, all lorises, including the slow lorises, have a specially adapted mechanism for defense against predation. [65][138][140] This results in severe bleeding, which sometimes causes shock or death. [63] Similar to the slender lorises, the fur around and directly above the eyes is dark. Slow loris saliva has been shown to be cytotoxic to human skin cells in laboratory experiments without the admix of BGE. Researchers believe that there are only a handful of this species left. Limited information on its status and ecology is the main hindrance to developing a conservation strategy for this species in India, state experts. The species is named ? Head-to-body length for the Bengal slow loris is 10 to 15 in (26 to 38 cm), and the primate weighs up to 4.4 lb (2 kg). Most are small, but an unnamed form dating to 15–16 mya is comparable in size to the largest living slow lorises. The foramen magnum (hole through which the spinal cord enters) faces directly backward. The species is distinguished by the presence of a white diamond pattern on its forehead. Other venomous mammals besides the slow loris include the duck-billed platypus, vampire bats, some shrews and moles, and solenodons (a shrew-like animal). A new species of slow loris has been discovered in Borneo. 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). If they are bitten by another slow loris in a fight, they will likely die. [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. The new slow loris species is found in the highlands of the island of Borneo and has been named Nycticebus kayan, after a major river, the Kayan, flowing through the region.The trio of scientists also found that two species previously considered sub-species in the Nycticebus genus are officially unique species. bancanus and N. borneanus—were elevated to species status, and a new species—N. [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. Slow loris venom is often harmful to humans and potentially dangerous. The animal is classified as “Vulnerable” by the IUCN since its population is vulnerable to habitat destruction, hunting, and the illegal pet trade. Slow lorises under human care are typically fed lots of fruit, which provides them with the wrong kind of energy for their gut microbes. Other species of slow loris include: In general, encounter rates are low; a combined analysis of several field studies involving transect surveys conducted in South and Southeast Asia determined encounter rates ranging from as high as 0.74 lorises per kilometer for N. coucang to as low as 0.05 lorises per kilometer for N. The slow loris has a food habit similar to the species mentioned above. 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. [64], The eyes of slow lorises are forward-facing, which gives stereo vision. They are omnivores, eating small animals, fruit, tree gum, and other vegetation. By Oishimaya Sen Nag on August 1 2017 in Environment. It is classified as “Vulnerable” by the IUCN as illegal hunting and habitat loss threatens the survival of the species. Lack of law enforcement further threatens slow loris species across their range (Nijman et … There are eight recognized species of slow lorises that include the Sunda slow loris, Javan slow loris, Bengal slow loris, pygmy slow loris, Bangka slow loris, Bornean slow loris, Philippine slow loris, and the Kayan River slow loris. The biggest threat to all slow loris species is their value as commodities in the exotic pet trade and for traditional medicines. The venom is administered through morphologically distinct dentition in the form of an adapted toothcomb. Slow lorises are a group of several species of nocturnal strepsirrhine primates that make up the genus Nycticebus. The Larissidae family consists of loris, galagos and potos, and consists of 9 genera and more than 25 species that are found in the south of Africa in the Sahara, southern India, Sri Lanka, Southeast Asia and eastern Indies. The slow lorises have large eyes that are forward facing. Slow Loris Facts Firstly, the term Slow Loris serves as the common name for eight known species of strepsirrhine primates. [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. They lack the opsin gene that would allow them to detect short wavelength light, which includes the colors blue and green. The slow loris has a tail hidden in the dense fur of its body. It is an omnivore that feeds on insects, nectar, fruit, tree gum, etc. [90], Little is known about the social structure of slow lorises, but they generally spend most of the night foraging alone. Its geographic range is larger than that of any other slow loris species. This species of slow loris prefers to inhabit evergreen forests within its range. These animals are nocturnal and arboreal in nature and generally, have an omnivorous diet. [122]. - Slow Lorises have a round head, large eyes (adapted at seeing at night), narrow snout, and a variety of distinctive coloration patterns that are species-dependent. Pygmy slow lorises are one of the few primate species that slip into torpor (an abbreviated type of hibernation) during cool months (late October to early April). The pale red to golden fur of the loris easily distinguishes it from the rest of the slow loris species. The bony palate (roof of the mouth) only goes as far back as the second molar. The pygmaeous slow loris is considered by some to be a member of the coucang species, but there is still debate (see Venom). [126][136][137], Within their countries of origin, slow lorises are very popular pets,[138] particularly in Indonesia. [121] Slow lorises (of the genus Nycticebus) are accepted as the only known venomous primate. The slow loris, a species of primate native to South-east Asia, rivals Justin Bieber as a viral internet sensation. [83] The Bengal slow loris (N. bengalensis) has the largest distribution of all the slow lorises[86] and can be found in Bangladesh, Cambodia, southern China, Northeast India, Laos, Burma, Thailand, and Vietnam. [75] Copulation often occurs while suspended with the hands and feet clinging to horizontal branches for support. The slow lorises are a group of nocturnal strepsirrhine primates that inhabit the Southeast Asia and its neighboring areas. Thailand is home to two species of slow loris; the greater slow loris (Nycticebus coucang) and the Bengal slow loris (Nycticebus bengalensis). 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. The Bangka slow loris (Nycticebus bancanus) inhabits the southwestern Bornean island of Bangka. [129] Infection, stress, pneumonia, and poor nutrition lead to high death rates among pet lorises. [8] Their intermembral index (ratio of arm to leg length) averages 89, indicating that their forelimbs are slightly shorter than their hind limbs. 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. See sample letter. Jhum cultivation, expansion of tea estates and the conversion of forests for agricultural uses are endangering the animal. [75][94] Adult males are highly territorial and are aggressive towards other males. 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. CURRENT RANGE: Tropical evergreen rainforests across Southeast Asia CURRENT THREATS: Deforestation and the illegal animal trade CONSERVATION STATUS: Endangered WHERE YOU CAN SEE THEM: In Southern Asia (from India east to China and the Philippines) and zoos all over the … 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. SPECIES: Slow loris (genus Nycticebus). 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. It is one of the smallest species of slow loris and weighs only 265 to 300 kg. This species and other members of the genus, which occur in other parts of Southeast Asia, are about 27–37 cm (about 11–15 inches) … [141] Furthermore, few know about their strong odor[142] or their painful bite, which may lead to anaphylaxis in some cases. This exotic pet includes some species that are facing dramatic decline in population, and among them, the Javan 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. An article in the Journal of Venom Research documented a survey of eighty people working with various species of slow lorises in zoos, rescue centers, and the wild over one year. A video of an animal being tickled has gained more than six million views. Slow lorises reproduce slowly, and the infants are initially parked on branches or carried by either parent. 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. It is the most threatened species of slow loris and is also listed in the 2010 list of "The World's 25 Most Endangered Primates.” Despite protective measures being implemented, the Javan slow loris continues to be poached for traditional medicine and captured for the exotic pet trade. This fact makes this mammal the only known venomous primate on earth. [60] The skull has prominent crests (ridges of bone). However, most taxonomic classifications group them separately as distinct species. Females reach sexual maturity at 18 to 24 months, while males are capable of reproducing at 17 months. [15] Molecular clock analysis suggests that slow lorises may have started evolving into distinct species about 10 mya. Slow Loris Adult slow lorises range in size from 21 to 38 cm, depending on the species, and weigh up to 2 kilograms. Vocal exchanges and alarm calls are limited; scent marking with urine is the dominant form of communication. [63] The trunk is longer than in other living strepsirrhines[73] because they have 15–16 thoracic vertebrae, compared to 12–14 in other living strepsirrhines. Javan Slow Loris – This species of slow Loris lives in Indonesia, specifically on the island of Java. All slow lorises are threatened by the wildlife trade and habitat loss. This is a small and highly specific suborder of primates native to one part of the world. 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 food habit of this species is similar to that of the others mentioned above. kayan—was also distinguished from the same. [43], Slow lorises have a round head[57] because their skull is shorter than in other living strepsirrhine. SPECIES: Slow loris (genus Nycticebus). IUCN labels the Philippine slow loris as a “Vulnerable” species. This fact makes this mammal the only known venomous primate on earth. ... Lorises belong to a family of primates known as Lorisidae, in which there are 9 genera and over 25 species. 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.
