Mammalia In The 10th Edition Of Systema Naturae
The Mammalia in the 10th edition of ''Systema Naturae'' forms one of six classes of animals in Carl Linnaeus's tenth reformed edition written in Latin. The following explanations are based on William Turton's translations who rearranged and corrected earlier editions published by Johann Friedrich Gmelin, Johan Christian Fabricius and Carl Ludwig Willdenow: Animals that suckle their young by means of lactiferous teats. In external and internal structure they resemble man: most of them are quadrupeds; and with man, their natural enemy, inhabit the surface of the Earth. The largest, though fewest in number, inhabit the ocean.'' Linnaeus divided the mammals based upon the number, situation, and structure of their teeth; mammals have the following characteristics: *Heart: two auricles, 2 ventricles. Warm, dark red blood; *Lungs: respires alternately; *Jaw: incombent, covered. Teeth usually within jaw; *Teats: lactiferous; *Organs of sense: tongue, nostrils, eyes, ears, and papillae of ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his Nobility#Ennoblement, ennoblement in 1761 as Carl von Linné#Blunt, Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In ...

Common Chimpanzee
The chimpanzee (''Pan troglodytes''), also known as simply the chimp, is a species of great ape native to the forest and savannah of tropical Africa. It has four confirmed subspecies and a fifth proposed subspecies. When its close relative the bonobo was more commonly known as the pygmy chimpanzee, this species was often called the common chimpanzee or the robust chimpanzee. The chimpanzee and the bonobo are the only species in the genus ''Pan''. Evidence from fossils and DNA sequencing shows that ''Pan'' is a sister taxon to the human lineage and is humans' closest living relative. The chimpanzee is covered in coarse black hair, but has a bare face, fingers, toes, palms of the hands, and soles of the feet. It is larger and more robust than the bonobo, weighing for males and for females and standing . The chimpanzee lives in groups that range in size from 15 to 150 members, although individuals travel and forage in much smaller groups during the day. The species lives i ...

Grivet
The grivet (''Chlorocebus aethiops'') is an Old World monkey with long white tufts of hair along the sides of its face. Some authorities consider this and all of the members of the genus ''Chlorocebus'' to be a single species, ''Cercopithecus aethiops''. As here defined, the grivet is restricted to Ethiopia, Sudan, Djibouti, and Eritrea. In the southern part of its range, it comes into contact with the closely related vervet monkey (''C. pygerythrus'') and Bale Mountains vervet (''C. djamdjamensis''). Hybridization between them is possible, and may present a threat to the vulnerable Bale Mountains vervet. Unlike that species, the grivet is common and rated as least concern by the IUCN. Physical description The grivet's facial skin, hands, and feet are black. The face has a white line above the eyes. It has long, white whiskers on the cheeks. The fur on the back has an olive color, while the front is white. The skin on the stomach has a blue tint. The fur has a bristly feel. The ...

Cottontop Tamarin
The cotton-top tamarin (''Saguinus oedipus'') is a small New World monkey weighing less than . This New World monkey can live up to 24 years, but most of them die by 13 years. One of the smallest primates, the cotton-top tamarin is easily recognized by the long, white sagittal crest extending from its forehead to its shoulders. The species is found in tropical forest edges and secondary forests in northwestern Colombia, where it is arboreal and diurnal. Its diet includes insects and plant exudates, and it is an important seed disperser in the tropical ecosystem. The cotton-top tamarin displays a wide variety of social behaviors. In particular, groups form a clear dominance hierarchy where only dominant pairs breed. The female normally gives birth to twins and uses pheromones to prevent other females in the group from breeding. These tamarins have been extensively studied for their high level of cooperative care, as well as altruistic and spiteful behaviors. Communica ...

Common Marmoset
The common marmoset (''Callithrix jacchus'') also called white-tufted marmoset or white-tufted-ear marmoset is a New World monkey. It originally lived on the northeastern coast of Brazil, in the states of Piaui, Paraiba, Ceará, Rio Grande do Norte, Pernambuco, Alagoas, and Bahia. Through release (both intentional and unintentional) of captive individuals, it has expanded its range since the 1920s to Southeast Brazil (its first sighting in the wild for Rio de Janeiro was in 1929), where it became an invasive species, raising concerns about genetic pollution of similar species, such as the buffy-tufted marmoset (''Callithrix aurita''), and predation upon bird nestlings and eggs. The whole-genome sequence of a female common marmoset was published on 20 July 2014. It became the first New World Monkey to have its genome sequenced. Physical description and morphology Common marmosets are very small monkeys with relatively long tails. Males and females are of similar size, wit ...

Hamadryas Baboon
The hamadryas baboon (''Papio hamadryas'' ) is a species of baboon within the Old World monkey family. It is the northernmost of all the baboons, being native to the Horn of Africa and the southwestern region of the Arabian Peninsula. These regions provide habitats with the advantage for this species of fewer natural predators than central or southern Africa where other baboons reside. The hamadryas baboon was a sacred animal to the ancient Egyptians and appears in various roles in ancient Egyptian religion, hence its alternative name of 'sacred baboon'.Swedell 2015 Description Apart from the striking sexual dimorphism (males are nearly twice as large as females, which is common to most baboons) this species also shows differences in coloration among adults. Adult males have a pronounced cape (mane and mantle), silver-white in color, which they develop around the age of ten, while the females are capeless and brown all over. Their faces range in color from reddish to tan to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crab-eating Macaque
The crab-eating macaque (''Macaca fascicularis''), also known as the long-tailed macaque and referred to as the cynomolgus monkey in laboratories, is a cercopithecine primate native to Southeast Asia. A species of macaque, the crab-eating macaque has a long history alongside humans. The species has been alternately seen as an agricultural pest, a sacred animal, and, more recently, the subject of medical experiments. The crab-eating macaque lives in matrilineal social groups of up to eight individuals dominated by females. Male members leave the group when they reach puberty. It is an opportunistic omnivore and has been documented using tools to obtain food in Thailand and Myanmar. The crab-eating macaque is a known invasive species and a threat to biodiversity in several locations, including Hong Kong and western New Guinea. The significant overlap in macaque and human living space has resulted in greater habitat loss, synanthropic living, and inter- and intraspecies conflict ...

Moustached Guenon
The moustached guenon or moustached monkey (''Cercopithecus cephus'') is a species of primate in the family Cercopithecidae. It is found in Angola, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea, and Gabon. This monkey is an arboreal, omnivorous, and medium-sized mammal. According to the IUCN, the population of the moustached monkeys is considered to be large; therefore, they are widely used in biological labs. Taxonomy The moustached guenon belongs to the genus '' Cercopithecus'', a genus of Old World monkeys, and in the ''C. cephus'' group. It is named by its unique moustached face in the monkeys, which has three recognized subspecies: (1) Red-tailed moustached monkey (''C. cephus cephus''); (2) Gray-tailed Moustached Monkey (''C. cephus cephodes''); (3) White-nosed Moustached Monkey (''C. cephus ngottoensis''). However, the ''C. cephus'' group also includes many other long-tailed monkey that has other unique ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diana Monkey
The Diana monkey (''Cercopithecus diana'') is an Old World monkey found in the high canopy forests in Sierra Leone, Liberia, and western Côte d’Ivoire. Named for its white brow which is said to resemble the bow of the Roman goddess Diana, this black-grey guenon has a white throat, crescent-shaped browband, ruff and beard. Taxonomy Two taxa formerly considered subspecies of the Diana monkey have recently been elevated to full species status: the roloway monkey (''C. roloway'') is found in Côte d'Ivoire and Ghana, and the Dryas monkey (''C. dryas'') found in the DR Congo. Distribution This species can be found in West Africa, from Sierra Leone to Côte d'Ivoire. Habitat The Diana monkey is found in the primary forests, and does not thrive in secondary forests. The species is regarded as endangered by the IUCN as well as by the United States Fish and Wildlife Service, the chief dangers to them being habitat destruction (they are now virtually confined to coastal areas) and ...

Red-faced Spider Monkey
The red-faced spider monkey (''Ateles paniscus'') also known as the Guiana spider monkey or red-faced black spider monkey, is a species of spider monkey found in the rain forests in northern South America. The species faces issues with hunting and habitat loss, so is listed as Vulnerable on the IUCN Redlist. Description The red-faced spider monkey has long, black hair and a red or pink face that is bare except for a few short, white hairs. Infants are born with dark faces, which lighten as they age. Sexual dimorphism in the species is small; the head-body length of the male is on average, while the female is around in length. The male weighs around , while the female weighs around . The tail is prehensile (capable of grasping) and its fingers and limbs are long, agile and strong. Behavior The red-faced spider monkey exhibits a fission-fusion society, associating with large groups of up to 30 individuals during the night, but choosing to spend the days travelling. At ...

Lion-tailed Macaque
The lion-tailed macaque (''Macaca silenus''), also known as the wanderoo, is an Old World monkey endemic to the Western Ghats of South India. Characteristics Lion-tailed macaques are covered in black fur, and have a striking gray or silver mane that surrounds their face which can be found in both sexes. The face itself is hairless and black, being pinkish in infants less than a year old. They are named not for their mane, but for their tail, which is long, thin, and naked, with a lion-like, black tail tuft at the tip. The size of their tail is about 25 cm (9.8 in) in length. Their eyes are a shade of hazelnut with highlighting black eyelids. Lion-tailed macaques, like other macaques, have deep cheek pouches useful for storing food, and are quadrupedal with opposable digits. The mane that surrounds its face gives this monkey its German name ''Bartaffe'' – "beard ape". With a head-body length of and a weight of , it ranks among the smaller macaques species. Offspring are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nomen Dubium
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
