Loris
Loris is the common name for the strepsirrhine mammals of the subfamily Lorinae (sometimes spelled Lorisinae) in the family Lorisidae. ''Loris'' is one genus in this subfamily and includes the slender lorises, ''Nycticebus'' is the genus containing the slow lorises, and ''Xanthonycticebus'' is the genus name of the pygmy slow loris. Description Lorises are nocturnal and arboreal. They are found in tropical and woodland forests of India, Sri Lanka, and parts of southeast Asia. Their locomotion is a slow and cautious climbing form of quadrupedalism. Some lorises are almost entirely insectivorous, while others also include fruits, gums, leaves, and slugs in their diet. Lorises, like most strepsirrhines, have a special adaptation called a " toothcomb" in their lower front teeth, which they use for grooming their fur and even injecting their venom. Female lorises practice ''infant parking'', leaving their infants behind in trees or bushes. Before they do this, they bathe the ...

Slow Loris
Slow lorises are a group of several species of Nocturnality, nocturnal Strepsirrhini, strepsirrhine primates that make up the genus ''Nycticebus''. Found in Southeast Asia and nearby 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 ''Xant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pygmy Slow Loris
The pygmy slow loris (''Xanthonycticebus pygmaeus'') is a species of slow loris found east of the Mekong, Mekong River in Vietnam, Laos, eastern Cambodia, and China. It occurs in a variety of forest habitats, including Tropical and subtropical dry broadleaf forests, tropical dry forests, semi-evergreen forest, evergreen, and evergreen forests. It was originally classified within ''Nycticebus'' until it was transferred to the genus ''Xanthonycticebus'' in 2022. Two species are recognised, the northern pygmy loris ''X. intermedius'' from northern Vietnam, Laos and China and the southern pygmy loris ''X. pygmaeus'' from southern Vietnam, Laos and Cambodia. The animal is Nocturnality, nocturnal and arboreal, crawling along branches using slow movements in search of prey. Unlike other primates, it does not leap. It lives together in small groups usually with one or two offspring. An adult can grow to around long and has a very short tail. It weighs about . Its diet consists of fruits, ...

Loris (genus)
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 Saint-Hila ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strepsirrhine
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 bicor ...

Lorisidae
Lorisidae (or sometimes Loridae) is a family of strepsirrhine primates. The lorisids are all slim arboreal animals and comprise the lorises, pottos, and angwantibos. Lorisids live in tropical, central Africa as well as in south and southeast Asia. Classification There are five genera and sixteen species of lorisid. * Order Primates ** Suborder Strepsirrhini: non-tarsier prosimians *** Infraorder Lemuriformes **** Superfamily Lemuroidea **** Superfamily Lorisoidea ***** Family Lorisidae ****** Subfamily Perodicticinae ******* Genus '' Arctocebus'', angwantibos ******* Genus ''Perodicticus'', pottos ****** Subfamily Lorisinae ******* Genus ''Loris'', slender lorises ******* Genus '' Nycticebus'', slow lorises ******* Genus '' Xanthonycticebus'', pygmy slow loris ***** Family Galagidae: galagos ** Suborder Haplorrhini: tarsiers, monkeys and apes Description Lorisids have a close, woolly fur, which is usually grey or brown, darker on the top side.

Toothcomb
A toothcomb (also called a tooth comb or dental comb) is a Dentition, dental structure found in some mammals, comprising a group of front teeth arranged in a manner that facilitates grooming, similar to a hair comb. The toothcomb occurs in Lemuriformes, lemuriform primates (which include lemurs and Lorisoidea, lorisoids), treeshrews, colugos, hyraxes, and some African antelopes. The structures evolved independently in different types of mammals through convergent evolution and vary both in dental composition and structure. In most mammals the comb is formed by a group of teeth with fine spaces between them. The toothcombs in most mammals include incisors only, while in lemuriform primates they include incisors and Canine tooth, canine teeth that tilt forward at the front of the lower jaw, followed by a canine-shaped first premolar. The toothcombs of colugos and hyraxes take a different form with the individual incisors being serrated, providing multiple wikt:tine, tines per toot ...

Lemuriformes
Lemuriformes is the sole extant infraorder of primate that falls under the suborder Strepsirrhini. It includes the lemurs of Madagascar, as well as the galagos and lorisids of Africa and Asia, although a popular alternative taxonomy places the lorisoids in their own infraorder, Lorisiformes. Lemuriform primates are characterized by a toothcomb, a specialized set of teeth in the front, lower part of the mouth mostly used for combing fur during grooming. Evolutionary history Lemuriform origins are unclear and debated. American paleontologist Philip Gingerich proposed that lemuriform primates evolved from one of several genera of European adapids based on similarities between the front lower teeth of adapids and the toothcomb of extant lemuriforms; however, this view is not strongly supported due to a lack of clear transitional fossils. Instead, lemuriforms may be descended from a very early branch of Asian cercamoniines or sivaladapids that immigrated to northern Africa. ...

Lorisoidea
Lorisoidea is a superfamily of nocturnal primates found throughout Africa and Asia. Members include the galagos and the lorisids. As strepsirrhines, lorisoids are related to the lemurs of Madagascar and are sometimes included in the infraorder Lemuriformes, although they are also sometimes placed in their own infraorder, Lorisiformes Gregory, 1915.

Leaves
A leaf (: leaves) is a principal appendage of the stem of a vascular plant, usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf, but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. The leaf is an integral part of the stem system, and most leaves are flattened and have distinct upper ( adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax, and other features. Leaves are mostly green in color due to the presence of a compound called chlorop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galago
Galagos , also known as bush babies or ''nagapies'' (meaning "night monkeys" in Afrikaans), are small nocturnal primates native to continental, sub-Sahara Africa, and make up the family Galagidae (also sometimes called Galagonidae). They are considered a sister group of the Lorisidae. According to some accounts, the name "bush baby" comes from either the animal's cries or its appearance. The Ghanaian name ''aposor'' is given to them because of their firm grip on branches. In both variety and abundance, the bush babies are the most successful strepsirrhine primates in Africa, according to the African Wildlife Foundation. Taxonomic classification and phylogeny Galagos are currently grouped into six genera. '' Euoticus'' is a basal sister taxon to all the other galagids. The 'dwarf' galagids recently grouped under the genus '' Galagoides'' have been found, based on genetic data, and supported by analysis of vocalisations and morphology, to actually consist of two clad ...

Orangutan
Orangutans are great apes native to the rainforests of Indonesia and Malaysia. They are now found only in parts of Borneo and Sumatra, but during the Pleistocene they ranged throughout Southeast Asia and South China. Classified in the genus ''Pongo'', orangutans were originally considered to be one species. In 1996, they were divided into two species: the Bornean orangutan (''P. pygmaeus'', with three subspecies) and the Sumatran orangutan (''P. abelii''); a third species, the Tapanuli orangutan (''P. tapanuliensis''), was identified definitively in 2017. The orangutans are the only surviving members of the subfamily Ponginae, which diverged genetically from the other hominids (gorillas, chimpanzees, and humans) between 19.3 and 15.7 million years ago. The most arboreal of the great apes, orangutans spend most of their time in trees. They have proportionally long arms and short legs, and have reddish-brown hair covering their bodies.
