[5] The toxin is obtained by licking a sweat gland on their arm, and the secretion is activated by mixing with saliva. The Bengal slow loris is a gum-eating, nocturnal, tree-dwelling primate species found in northeast India. The dark, contrasting facial features and unique markings on the face help to distinguish this species of slow loris. The slow loris has a food habit similar to the species mentioned above. Seconde Famille. Slow lorises are one of only six mammal species known to be venomous. 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. 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). [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. [24] Consequently, there has been some disagreement over the identity of Tardigradus coucang; currently the name is given to the Sunda slow loris. [99], If cornered, they may adopt a defensive posture by curling up and lunging at the predator. [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. [63], Slow lorises have a powerful grasp with both their hands and feet due to several specializations. [22] A distinguishing feature of the slow loris skull is that the occipital bone is flattened and faces backward. Of the 10 different species of Lorises, the IUCN lists 1 species as critically endangered, 1 species as endangered, 4 species as vulnerable, 1 species as least concern, and has not yet evaluated the 3 other species. It is an omnivore that feeds on insects, nectar, fruit, tree gum, etc. A new species of slow loris has been discovered in Borneo. All four of these are expected to be listed with at least the same, if not a higher-risk, conservation status. See sample letter. Secondary toxins may be introduced from the consumption of wild food, augmenting the toxicity. 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. [117][118] Slow lorises can use both hands to eat while hanging upside down from a branch. [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. [51], In 2012, two taxonomic synonyms (formerly recognized as subspecies) of N. menagensis—N. 2010, Shepherd et al, 2004). Pygmy slow loris-Wikipedia. [129][137], Despite frequent advertisements by pet shops in Japan, the World Conservation Monitoring Centre reported that only a few dozen slow lorises were legally imported in 2006, suggesting frequent smuggling. Before stashing their offspring in a secure location, female slow lorises will lick their brachial glands, and then groom their young with their toothcomb, depositing the toxin on their fur. [140][144] The slow lorises found in animal markets are usually underweight and malnourished, and have had their fur dyed, which complicates species identification at rescue centers. They move with slow, deliberate hand-over-hand movements … through the trees but can move quickly if necessary. 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. In the wild, envenomation occurs from intraspecific competition; whereby two slow lorises fight for mates, food or territory. This fact makes this mammal the only known venomous primate on earth. Other species of slow loris include: 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. [135][136] They are especially popular or trendy in Japan, particularly among women. Lemuriens. Males are highly territorial. By Oishimaya Sen Nag on August 1 2017 in Environment. [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. [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. Their only documented predators—apart from humans—include snakes, changeable hawk-eagles and orangutans, although cats, viverrids and sun bears are suspected. [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. 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) … According to Nekaris, this adaptation—along with vocalizations, movement, and coloration patterns similar to those of true cobras—may have evolved through Müllerian mimicry to protect slow lorises when they need to move across the ground due to breaks in the canopy. [110] The Sunda slow loris eats insects that other predators avoid due to their repugnant taste or smell. Found in Southeast Asia and bordering regions, they range from Bangladesh and northeast India in the west to the Sulu Islands of the Philippines in the east and Yunnan Province in north China to Java Island in the south. They move with slow, deliberate hand-over-hand movements ... 5" x 7" full-color photo of your species; Species spotlight card, full of fascinating information about the animal; FREE priority shipping; Personalized acknowledgment letter to your gift recipient. Slow lorises reproduce slowly, and the infants are initially parked on branches or carried by either parent. [132] Furthermore, local trade is illegal because every nation in which they occur naturally has laws protecting them. "CITES Proposal Highlights Rarity of Asian Nocturnal Primates (Lorisidae: "A molecular phylogeny of living primates", "Indonesia's Slow Lorises Suffer in Trade", "Fossil evidence for an ancient divergence of lorises and galagos", "A collection of mammals from Sumatra, with a review of genera, "Note on the nomenclature of the Northern Slow-loris", "Distribution survey of Bengal Slow Loris, 10.1002/(SICI)1098-2345(1997)43:2<159::AID-AJP5>3.0.CO;2-W, "Fast food for slow lorises: is low metabolism related to secondary compounds in high-energy plant diet? [60] The skull has prominent crests (ridges of bone). If they are bitten by another slow loris in a fight, they will likely die. The name derives from the Ancient Greek: νύξ, romanized: (nyx), genitive form of νυκτός (nyktos, "night"), and κῆβος (kêbos, "monkey"). [106] Infants are either parked on branches while their parents find food or else are carried by one of the parents. [45] Species differentiation was based largely on differences in morphology, such as size, fur color, and head markings. Their eye rings are separated by a white stripe and their lips and noses are covered by moist skin. 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. [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.
