Silvery Lutung
The silvery lutung (''Trachypithecus cristatus''), also known as the silvered leaf monkey or the silvery langur, is an Old World monkey. It is arboreal, living in coastal, mangrove, and riverine forests in Sumatra, Borneo, Java, as well as in parts of the southwestern Malay Peninsula, the Natuna Islands, and other nearby islands. It is the type species of its species group. Description The silvery lutung is a medium-sized monkey with a long, non-prehensile tail. It has grey-tipped, dark brown or black fur, giving it a uniform silvery appearance. Unlike some related species, there are no paler markings on the face or body, except for a patch of whitish hair on the groin of females. A crest of fur runs along the top of the head, and the hair on the cheeks is long, often obscuring the ears. The hands and feet are hairless, with dark-coloured skin, and have opposable thumbs and toes. Females range from in head-body length, with an average weight of and a tail length of . Males are ...

Bako National Park
Bako National Park () is a national park in Kuching District, Kuching Division, Sarawak, Malaysia. Established in 1957, it is the oldest national park in Sarawak. It covers an area of at the tip of the Muara Tebas peninsula at the mouth of the Bako and Kuching Rivers. It is approximately by road from Kuching. Millions of years of erosion of the sandstone have created a coastline of steep cliffs, rocky headlands and stretches of white, sandy bays. Wave erosion at the base of the cliffs has carved many of the rocky headlands into fantastically shaped sea arches and seastacks with colored patterns formed by iron deposition. The most famous of them was shaped like a cobra's head which could be spotted on a boat ride from the headquarters or one of the beaches. This collapsed in 2024 and is no longer present. Some of these rock formations can be seen on entry to the Teluk Assam Beach, which fronts the park. The park can only be reached by a 20-minute boat ride from the village ...

Stomach
The stomach is a muscular, hollow organ in the upper gastrointestinal tract of Human, humans and many other animals, including several invertebrates. The Ancient Greek name for the stomach is ''gaster'' which is used as ''gastric'' in medical terms related to the stomach. The stomach has a dilated structure and functions as a vital organ in the digestive system. The stomach is involved in the gastric phase, gastric phase of digestion, following the cephalic phase in which the sight and smell of food and the act of chewing are stimuli. In the stomach a chemical breakdown of food takes place by means of secreted digestive enzymes and gastric acid. It also plays a role in regulating gut microbiota, influencing digestion and overall health. The stomach is located between the esophagus and the small intestine. The pyloric sphincter controls the passage of partially digested food (chyme) from the stomach into the duodenum, the first and shortest part of the small intestine, where p ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Phayre's Leaf Monkey
Phayre's leaf monkey (''Trachypithecus phayrei''), also known as Phayre's langur, is a species of Old World monkey native to South Asia and Southeast Asia, namely India, Bangladesh, and Myanmar. Populations from further east are now thought to belong to other species. It is listed as Endangered on the IUCN Red List and is threatened by hunting and loss of habitat. The species epithet commemorates Arthur Purves Phayre. Taxonomy The scientific name ''Presbytis phayrei'' was used by Edward Blyth in 1847 for two young individuals captured alive in the Arakan Mountains in Myanmar. Phayre's langur is one of the most widespread members of the genus, but its actual distribution and intraspecific taxonomy remain controversial. Previously, three subspecies were recognized, namely ''T. p. crepusculus'', ''T. p. phayrei'' and ''T. p. shanicus''. Three separate species ''T. phayrei'', ''T. melamera'' (formerly ''T. p. shanicus''), and '' T. popa sp. nov.'' have been proposed based on m ...

Javan Lutung
The East Javan langur (''Trachypithecus auratus''), also known as the ebony lutung, Javan langur or Javan lutung, is an Old World monkey from the Colobinae subfamily. It is most commonly glossy black with a brownish tinge to its legs, sides, and " sideburns". It is found on the island of Java, as well as on several of the surrounding Indonesian islands. The Latin word ''auratus'' in its scientific name means "golden" and refers to a less common color variant. The common name golden langur refers to a different species. Description Like all langurs, this species' tail is noticeably long, measuring up to 98 cm in length while the body is only around 55 cm long. The two subspecies of this monkey are fairly similar in appearance and are geographically separated; males and females are both usually glossy black, although the females pale, yellowish-white patch around the pubic area. Juveniles of both subspecies are orange in color. The nominate subspecies ''Trachypithecus a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trachypithecus Cristatus Species Group
''Trachypithecus'' (derived from Greek , meaning "rough" and , meaning "monkey") is a genus of Old World monkeys containing species known as lutungs, langurs, or leaf monkeys. Their range is much of Southeast Asia (northeast India, Vietnam, southern China, Borneo, Thailand, Java, and Bali). The name "lutung" comes from the Sundanese language meaning "blackness", ultimately from Proto-Austronesian *''luCuŋ'' (which originally referred to the Formosan rock macaque); it is preferred in one paper because the authors wanted the name langurs to only refer to monkeys in the genus ''Semnopithecus'', although some "lutungs" are now "langurs" again. Evolution Genetic analysis indicates that the ancestors of the modern species of lutung first differentiated from one another a little over 3 million years ago, during the late Pliocene. The various species alive today then diverged during the Pleistocene, presumably driven by habitat changes during the Ice Ages. The oldest fossils clea ...

Selangor Silvered Langur
The Selangor silvered langur (''Trachypithecus selangorensis'') is a species of leaf monkey found on the west coast of Peninsular Malaysia. It had been previously considered a form of silvery lutung. Roos and colleagues elevated this population to a subspecies level, ''Trachypithecus cristatus selangorensis'', in 2008. It has since come to be regarded by primatologists as a separate species, ''Trachypithecus selangorensis''. Description The Selangor silvered langur has a gray body with a black face and black feet and hands. The type specimen had a head and body length of and a tail that was long. The closely related silvery lutung has an average head and body length of for females and for males. The silvery lutung has an average weight of for females and for males. The Selangor silvered langur differs from the silvery lutung in the shape of its whiskers. The Selangor silvered langur has long, straight whiskers while the silvery lutung has mussel-shaped whiskers. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intestine
The gastrointestinal tract (GI tract, digestive tract, alimentary canal) is the tract or passageway of the digestive system that leads from the mouth to the anus. The tract is the largest of the body's systems, after the cardiovascular system. The GI tract contains all the major organs of the digestive system, in humans and other animals, including the esophagus, stomach, and intestines. Food taken in through the mouth is digested to extract nutrients and absorb energy, and the waste expelled at the anus as feces. ''Gastrointestinal'' is an adjective meaning of or pertaining to the stomach and intestines. Most animals have a "through-gut" or complete digestive tract. Exceptions are more primitive ones: sponges have small pores ( ostia) throughout their body for digestion and a larger dorsal pore ( osculum) for excretion, comb jellies have both a ventral mouth and dorsal anal pores, while cnidarians and acoels have a single pore for both digestion and excretion. The human gas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruminant
Ruminants are herbivorous grazing or browsing artiodactyls belonging to the suborder Ruminantia that are able to acquire nutrients from plant-based food by fermenting it in a specialized stomach prior to digestion, principally through microbial actions. The process, which takes place in the front part of the digestive system and therefore is called foregut fermentation, typically requires the fermented ingesta (known as cud) to be regurgitated and chewed again. The process of rechewing the cud to further break down plant matter and stimulate digestion is called rumination. The word "ruminant" comes from the Latin ''ruminare'', which means "to chew over again". The roughly 200 species of ruminants include both domestic and wild species. Ruminating mammals include cattle, all domesticated and wild bovines, goats, sheep, giraffes, deer, gazelles, and antelopes.Fowler, M.E.
