[75] Copulation often occurs while suspended with the hands and feet clinging to horizontal branches for support. The Bangka slow loris has a toxic bite. [141] Furthermore, few know about their strong odor[142] or their painful bite, which may lead to anaphylaxis in some cases. Slow Loris . Likewise, gestation lasts 185 to 197 days, and the young weigh between 30 and 60 grams (1.1 and 2.1 oz) at birth.

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. The first mandibular premolar is elongated, and the last molar has three cusps on the crown, the shortest of which is near the back. Slow lorises are a group of several species of nocturnal strepsirrhine primates that make up the genus Nycticebus. The marks remaining after gouging can be used by field workers to assess loris presence in an area. Its arms and hands ar… [62], The ears are small,[8] sparsely covered in hair, and hidden in the fur. [8] Their intermembral index (ratio of arm to leg length) averages 89, indicating that their forelimbs are slightly shorter than their hind limbs. The length of the animals ranges from 19 to 23 cm. [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. [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. The animal measures about 293 mm from head to tail. It is generally solitary by nature and has a very low metabolic rate. [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. 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. 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. Other venomous mammals besides the slow loris include the duck-billed platypus, vampire bats, some shrews and moles, and solenodons (a shrew-like animal). 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. [64], The eyes of slow lorises are forward-facing, which gives stereo vision. 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. [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. The species is also classified as “Vulnerable” since it has suffered for decades from the ill effects of the illegal wildlife trade and habitat loss on their population. Slow lorises are one of only six mammal species known to be venomous. [57] As with other members of Lorisidae, its interorbital distance is shorter than in lemurs. Bengal Slow Loris . [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). 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. Further studies by scientists are required. The slow loris has a food habit similar to the species mentioned above. [65][138][140] This results in severe bleeding, which sometimes causes shock or death. Seconde Famille. They lack the opsin gene that would allow them to detect short wavelength light, which includes the colors blue and green. It is so easy to get access to wild-caught lorises, it is highly doubtful that a seller who claims to have captive-bred ones is telling the truth. [52] The Javan slow loris (N. javanicus) is only found on the island of Java in Indonesia. This species of slow loris is arboreal and nocturnal in nature. 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. [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. For example, slow lorises can feed on Gluta bark, which may be fatal to humans. [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. [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. [140][144] Without their teeth, the animals can no longer fend for themselves in the wild, and must remain in captivity for life. Bengal slow lorises, like other slow loris species, are gummivores, i.e., they feed primarily on plant gums and sap. [110] The Sunda slow loris eats insects that other predators avoid due to their repugnant taste or smell. - The Slow Loris could be found in … The Nycticebus genus contains slow Lorises, of which there are 8 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. [96] When disturbed, slow lorises can also produce a low buzzing hiss or growl. Conservationists hope the finding will add impetus to efforts to protect the double-tongued animals. However, most taxonomic classifications group them separately as distinct species. Slow lorises are nocturnal and arboreal, or tree-dwelling, primates. [74] This gives them greater mobility when twisting and extending towards nearby branches. Slow lorises reproduce slowly, and the infants are initially parked on branches or carried by either parent. The slow lorises are two of the three species of loris and are classified as the genus Nycticebus. [65], Dental infection is common and is fatal in 90% of cases. [91][92] Individuals sleep during the day, usually alone but occasionally with other slow lorises. These slow lorises prefer to live in groups with a few offsprings. Most members of this genus are all commonly referred to as a slow loris. The animal is classified as “Vulnerable” by the IUCN since its population is vulnerable to habitat destruction, hunting, and the illegal pet trade. SPECIES: Slow loris (genus Nycticebus). In the wild, envenomation occurs from intraspecific competition; whereby two slow lorises fight for mates, food or territory. [72] Slow lorises have stout bodies,[63] and their tails are only stubs and hidden beneath the dense fur. 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. [126] Slow lorises are also stress-sensitive and do not do well in captivity. Researchers have discovered a new species of slow loris, Nycticebus kayan. There are 10 different species of Lorises, which researchers divide into 2 genuses. 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. Most notably, the most unique trait of animals in this remarkable group is that each of the species has a toxic bite. The species is classified as “Vulnerable” on the Red List of IUCN.

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. 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. [100] Little is known about the predation of slow lorises. 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. [139] They are seen as a "living toy" for children by local people or are bought out of pity by Western tourists or expatriates. Rachel Munds, Anna Nekaris and Susan Ford based these taxonomic revisions on distinguishable facial markings. [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. When threatened, slow lorises may also lick their brachial glands and bite their aggressors, delivering the toxin into the wounds. There are several protected species of mammals on the island, including the binturong, long-tailed macaque, slow loris, black giant squirrel, red giant flying squirrel, mouse deer, brush-tailed porcupine, and common palm civet, from a total of 45 species of mammals and 138 species of birds, including the majestic frigatebird.
