Nycticebus
Slow lorises are a group of several species of nocturnal strepsirrhine primates that make up the genus ''Nycticebus''. Found in Southeast Asia and bordering areas, they range from Bangladesh and Northeast India in the west to the Sulu Archipelago in the Philippines in the east, and from Yunnan province in China in the north to the island of Java in the south. 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. coucang''), Bengal slow loris (''N. bengalensis''), Javan slow loris (''N. javanicus''), Philippine slow loris (''N. menagensis''), Bangka slow loris (''N. bancanus''), Bornean slow loris (''N. borneanus''), Kayan River slow loris (''N. kayan'') and Sumatran slow loris (''N. hilleri''). A ninth species, the pygmy slow loris (''X. pygmaeus''), was recently moved to the new genus '' Xanthonycticebus''. After ...

Sunda Slow Loris
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 from head to tail and weighs between . Like other slow lorises, it has a wet nose (rhinarium), a round head, small ears hidden in thick fur, a flat face, large eyes and a vestigial tail. The Sunda slow loris is nocturnal and arboreal, typically occurring in evergreen forests. It prefers rainforests with continuous dense canopies and has an extremely low metabolic rate compared to other mammals of its size. Its diet consists of sap, floral nectar, fruit and arthropods. It will feed on exudates such as gum and sap by licking wounds in trees. The species is generally solitary; one study showed only 8% of its active time was spent near other individuals. Social behavior makes up a very small part of the activity budget, though it has monogamous mating system with the offspring li ...

Nycticebus Menagensis
The Philippine slow loris (''Nycticebus menagensis'') is a strepsirrhine primate and a species of slow loris that is native to the north and east coastal areas of the island of Borneo, as well as the Sulu Archipelago in the Philippines. The species was first named as the Bornean slow loris in 1892, but lumped into the widespread Sunda slow loris (''N. coucang'') in 1952. However, it was promoted to full species status – again as the Bornean slow loris – based on molecular analysis in 2006. In 2013, two former subspecies of the Bornean slow loris were elevated to species status, and a new species—'' N. kayan''—was recognized among the Bornean population. Weighing , it is one of the smallest of the slow lorises, and can be distinguished from other slow lorises by its pale golden to red fur, the lack of markings on its head, and consistent absence of a second upper incisor. Like other slow lorises, it has a vestigial tail, round head, short ears, a curved grooming c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bengal Slow Loris
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. Its geographic range is larger than that of any other slow loris species. Considered a subspecies of the Sunda slow loris (''N. coucang'') until 2001, phylogenetic analysis suggests that the Bengal slow loris is most closely related to the Sunda slow loris. However, some individuals in both species have mitochondrial DNA sequences that resemble those of the other species, due to introgressive hybridization. It is the largest species of slow loris, measuring from head to tail and weighing between . Like other slow lorises, it has a wet nose (rhinarium), a round head, flat face, large eyes, small ears, a vestigial tail, and dense, woolly fur. The toxin it secretes from its brachial gland (a scent gland in its arm) differs chemically from that of other slow loris species and may be used to commu ...

Nycticebus Borneanus
''Nycticebus borneanus'', the Bornean slow loris, is a strepsirrhine primate and a species of slow loris that is native to central south Borneo in Indonesia. Formerly considered a subspecies or synonym of '' N. menagensis'', it was promoted to full species status in 2013 when a study of museum specimens and photographs identified distinct facial markings, which helped to differentiate it as a separate species. It is distinguished by its dark, contrasting facial features, as well as the shape and width of the stripes of its facial markings. As with other slow lorises, this arboreal and nocturnal species primarily eats insects, tree gum, nectar, and fruit and has a toxic bite, a unique feature among primates. Although not yet evaluated by the International Union for Conservation of Nature (IUCN), it is likely to be listed as "Vulnerable" or placed in a higher-risk category when its conservation status is assessed. It is primarily threatened by habitat loss and the illegal w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Javan Slow Loris
The Javan slow loris (''Nycticebus javanicus'') is a strepsirrhine primate and a species of slow loris native to the western and central portions of the island of Java, in Indonesia. Although originally described as a separate species, it was considered a subspecies of the Sunda slow loris (''N. coucang'') for many years, until reassessments of its morphology and genetics in the 2000s resulted in its promotion to full species status. It is most closely related to the Sunda slow loris and the Bengal slow loris (''N. bengalensis''). The species has two forms, based on hair length and, to a lesser extent, coloration. Its forehead has a prominent white diamond pattern, which consists of a distinct stripe that runs over its head and forks towards the eyes and ears. The Javan slow loris weighs between and has a head-body length of about . Like all lorises, it is arboreal and moves slowly across vines and lianas instead of jumping from tree to tree. Its habitat includes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nycticebus Bancanus
The Bangka slow loris (''Nycticebus bancanus'') is a strepsirrhine primate and a species of slow loris that is native to southwestern Borneo and the island of Bangka. Originally considered a subspecies or synonym of the Bornean slow loris ('' N. menagensis''), it was promoted to full species status in 2013 when a study of museum specimens and photographs identified distinct facial markings, which helped to differentiate it as a separate species. It is distinguished by the crimson red fur on its back, light-colored facial features, as well as the shape and width of the stripes of its facial markings. As with other slow lorises, this arboreal and nocturnal species primarily eats insects, tree gum, nectar, and fruit and has a toxic bite, a unique feature among primates. Although not yet evaluated by the International Union for Conservation of Nature (IUCN), it is likely to be listed as "Vulnerable" or placed in a higher-risk category when its conservation status is assesse ...

Nycticebus Kayan
The Kayan River slow loris (''Nycticebus kayan'') is a strepsirrhine primate and a species of slow loris that is native to the northern and central highland region of the island of Borneo. The species was originally thought to be a part of the Bornean slow loris ('' N. menagensis'') population until 2013, when a study of museum specimens and photographs identified distinct facial markings, which helped to differentiate it. It is distinguished by the high contrast of its black and white facial features, as well as the shape and width of the stripes of its facial markings. The species is named after the Kayan River, which runs through its native habitat. As with other slow lorises, this arboreal and nocturnal species primarily eats insects, tree gum, nectar, and fruit and has a toxic bite, a unique feature among primates. Although not yet evaluated by the International Union for Conservation of Nature (IUCN), it is likely to be listed as "Vulnerable" or placed in a highe ...

Nycticebus Linglom
? ''Nycticebus linglom'' is a fossil strepsirrhine primate from the Miocene of Thailand. Known only from a single tooth, an upper third molar, it is thought to be related to the living slow lorises (genus ''Nycticebus''), but the material is not sufficient to assign the species to ''Nycticebus'' with certainty, and the species name therefore uses open nomenclature. With a width of 1.82 mm, this tooth is very small for a primate. It is triangular in shape, supported by a single root, and shows three main cusps, in addition to various crests. The absence of a fourth cusp, the hypocone, distinguishes it from various other prosimian primates. Taxonomy ? ''Nycticebus linglom'' was described in 1997 by French paleontologists Pierre Mein and Léonard Ginsburg in a report on the fossil mammals of Li Mae Long, a Miocene site in Thailand, about 17–18 million years old.Mein and Ginsburg, 1997, p. 805 The animal is known from a single tooth, and on the basis of comparison ...

Sumatran Slow Loris
The Sumatran slow loris (''Nycticebus hilleri'') is a strepsirrhine primate and a species of slow loris that is native to Sumatra. While this species used to be considered a junior synonym of the Sunda slow loris, it is now recognized by the IUCN as a full species. This species is named after Hiram M. Hiller Jr., who collected the holotype of this species while exploring the East Indies The East Indies (or simply the Indies), is a term used in historical narratives of the Age of Discovery. The Indies refers to various lands in the East or the Eastern hemisphere, particularly the islands and mainlands found in and aroun ... in 1901.

Slender Loris
The slender lorises (''Loris'') are a genus of loris native to India and Sri Lanka. The genus comprises two species, the red slender loris found in Sri Lanka and the gray slender loris from Sri Lanka and India. Slender lorises spend most of their life in trees, traveling along the tops of branches with slow and precise movements. They are found in tropical rainforests, scrub forests, semi- deciduous forests, and swamps. The primates have lifespans of approximately 15 years and are nocturnal. Slender lorises generally feed on insects, reptiles, plant shoots, and fruit. Taxonomy The type species was named '' Lemur tardigradus'' by Linnaeus in 1758. The name ''Loris'' is first reported Georges-Louis Leclerc, Comte de Buffon in 1765, representing the Dutch '' loeris'' meaning "clown". According to Buffon, the name ''loeris'' had been in use for some time by Dutch naturalists for the "sloths of Ceylon". The genus ''Loris'' was separated from lemurs by Étienne Geoffroy Sai ...

Primate
Primates are a diverse order (biology), order of mammals. They are divided into the Strepsirrhini, strepsirrhines, which include the lemurs, galagos, and lorisids, and the Haplorhini, haplorhines, which include the Tarsiiformes, tarsiers and the Simiiformes, simians (monkeys and apes, the latter including humans). Primates arose 85–55 million years ago first from small Terrestrial animal, terrestrial mammals, which adapted to living in the trees of tropical forests: many primate characteristics represent adaptations to life in this challenging environment, including large brains, visual acuity, color vision, a shoulder girdle allowing a large degree of movement in the shoulder joint, and dextrous hands. Primates range in size from Madame Berthe's mouse lemur, which weighs , to the eastern gorilla, weighing over . There are 376–524 species of living primates, depending on which classification is used. New primate species continue to be discovered: over 25 species were d ...

Strepsirrhini
Strepsirrhini or Strepsirhini (; ) is a suborder of primates that includes the lemuriform primates, which consist of the lemurs of Madagascar, galagos ("bushbabies") and pottos from Africa, and the lorises from India and southeast Asia. Collectively they are referred to as strepsirrhines. Also belonging to the suborder are the extinct adapiform primates which thrived during the Eocene in Europe, North America, and Asia, but disappeared from most of the Northern Hemisphere as the climate cooled. Adapiforms are sometimes referred to as being "lemur-like", although the diversity of both lemurs and adapiforms does not support this comparison. Strepsirrhines are defined by their "wet" (moist) rhinarium (the tip of the snout) – hence the colloquial but inaccurate term "wet-nosed" – similar to the rhinaria of canines and felines. They also have a smaller brain than comparably sized simians, large olfactory lobes for smell, a vomeronasal organ to detect pheromones, and a bicornuate ...
