Pitheciine
Pitheciinae is a subfamily of the New World monkey family Pitheciidae. It contains three genera and 14 species. Pitheciines are forest dwellers from northern and central South America, east of the Andes. They are small to medium-sized primates, with a stocky build due to their close skin. The skin is covered in shaggy fur, its coloring varies depending upon species from black to grey and brown up to white. Parts of the face can be bald. The tail, which is not used for grasping but for balance, is also hairy, although the uakari's tail is only a stub. Like most New World monkeys, they are diurnal and arboreal. They are good climbers and spend the majority of their life in the trees. They live in groups ranging in number from small groups (such as with the saki monkeys ) to as many as 50 animals. They communicate with a set of sounds which typically includes high cries and a nearly bird-like twitter. Pitheciines are generally omnivores, the main part of their diet coming from fr ...

White-faced Saki
The white-faced saki (''Pithecia pithecia''), called the Guianan saki and the golden-faced saki, is a species of the New World saki monkey. They can be found in Brazil, French Guiana, Guyana, Suriname and Venezuela. This species lives in the understory and lower canopy of the forest, feeding mostly on fruits, nuts, seeds, and insects. Although they are arboreal creatures and are specialists of swinging from tree to tree (brachiation), they are also terrestrial when foraging. White-faced sakis typically live around 14 years in their natural habitat and have been recorded to live up to 36 years in captivity. Sakis are active in the day and sleep highly elevated (15-20m) in trees with many leaves to shelter them from weather and flying predators. A formerly recognized subspecies of this monkey, ''P. p. chrysocephala'', was elevated to full species status as '' P. chrysocephala'' in 2014. Reproduction and Sexual Dimorphism In captivity, female white-faced sakis experience ovarian c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Gray's Bald-faced Saki
''Gray's Anatomy'' is a reference book of human anatomy written by Henry Gray, illustrated by Henry Vandyke Carter, and first published in London in 1858. It has gone through multiple revised editions and the current edition, the 42nd (October 2020), remains a standard reference, often considered "the doctors' bible". Earlier editions were called ''Anatomy: Descriptive and Surgical'', ''Anatomy of the Human Body'' and ''Gray's Anatomy: Descriptive and Applied'', but the book's name is commonly shortened to, and later editions are titled, ''Gray's Anatomy''. The book is widely regarded as an extremely influential work on the subject. Publication history Origins The English anatomist Henry Gray was born in 1827. He studied the development of the endocrine glands and spleen and in 1853 was appointed Lecturer on Anatomy at St George's Hospital Medical School in London. In 1855, he approached his colleague Henry Vandyke Carter with his idea to produce an inexpensive and acce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Burnished Saki
The burnished saki (''Pithecia inusta'') is a species of saki monkey, a type of New World monkey. It is found in central Peru and a small portion of adjacent Brazil. Taxonomy It was described in 1823 by Johann Baptist von Spix, but was later merged with the monk saki (''P. monachus''). However, a 2014 study revived it as a distinct species based on differences in pelage coloration of juvenile individuals. The American Society of Mammalogists, IUCN Red List, and ITIS all follow this classification. Distribution This species is found throughout much of central Peru, primarily in the Ucayali River watershed, and a small portion of adjacent western Brazil. Description Adult individuals have a face covered in a burnt tan-colored fur. It can be distinguished from ''P. monachus'' by the facial coloration of juveniles, with juvenile males having closely pressed white hairs and females having gray-black or brownish faces that turn white, in contrast to the two-toned brown and white ...

Hairy Saki
The hairy saki (''Pithecia hirsuta'') is a species of saki monkey, a type of New World monkey. It is found in northern Peru, southern Colombia, and a small portion of northwestern Brazil. Taxonomy It was described in 1823 by Johann Baptist von Spix, but was later merged with the monk saki (''P. monachus''). However, a 2014 study revived it as a distinct species based on differences in pelage coloration. The American Society of Mammalogists, IUCN Red List, and ITIS all follow this classification. Distribution This species is found roughly at the intersection between Brazil, Peru, and Colombia, and ranges west of the Rio Negro, north of the Solimões River & Napo River, and south of the Japurá River. It is not known how far west it occurs, and where the boundary between this species and Miller's saki (''P. milleri'') is. Description It can be considered the most uniform and plain of the sakis, with very little differences in coloration between males and females. Both are l ...

Golden-faced Saki
The golden-faced saki (''Pithecia chrysocephala'') is a species of saki monkey, a type of New World monkey. It is found in Brazil north of the Amazon, on both sides of the Rio Negro. This species was formerly considered a subspecies of the white-faced saki The white-faced saki (''Pithecia pithecia''), called the Guianan saki and the golden-faced saki, is a species of the New World saki monkey. They can be found in Brazil, French Guiana, Guyana, Suriname and Venezuela. This species lives in the und ... (''P. pithecia''), but was raised to full species status in 2014. The species is named for the coloration of the male, which has black body hair but orange or red-brown facial hair. The female has lighter body color and more bare skin on the face, with lines of orange hair extending down from below the eyes around the snout, as well as orange ventral fur. The golden-faced saki features a smaller, less prognathic, and less spherical cranial vault than the white-faced saki. Refere ...

Cazuza's Saki
Cazuza's saki (''Pithecia cazuzai'') is a species of saki monkey, a type of New World monkey. It is Endemism, endemic to northwestern Brazil. Taxonomy Populations in this species were formerly classified within the Rio Tapajós saki (''P. irrorata''), but a 2014 study found these populations to have a distinct Fur, pelage from any other species in the genus, and they were thus reclassified into their own species, ''P. cazuzai''. The American Society of Mammalogists, IUCN Red List, and Integrated Taxonomic Information System, ITIS all follow this classification. The species is named after renowned Brazilian Primatology, primatologist Dr. José de Sousa e Silva Júnior, nicknamed "Cazuza". Distribution It is known only from a small region of northern Brazil in the state of Amazonas (Brazilian state), Amazonas, where it is found south of the Solimões River on either side of the Juruá River at Fonte Boa, Amazonas, Fonte Boa and Uarini.

Equatorial Saki
The equatorial saki (''Pithecia aequatorialis''), also called the red-bearded saki, is a species of saki monkey, a type of New World monkey. It is found in northeastern Peru and Ecuador. Not much is known about the equatorial saki, its range being specifically unknown. Description The equatorial saki weighs between 2 - 2.5 kg, has a head-body length of 39 – 44 cm, and a tail length of 45 – 47 cm. The species' tail in not prehensile, relying on its arm and leg strength to carry itself from branch to branch. The equatorial saki is also sexually dimorphic. It is often confused for the monk saki, but the reddish throat and chest of the equatorial saki set it apart. Ecology The equatorial saki is diurnal. The species is frugivorous, but seeds and nuts constitute a large part of diet. This species also consumes leaves and insects, especially ants. The fruits that this species consumes have hard pericarps. Most of its time is spent foraging in the middle to upper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omnivore
An omnivore () is an animal that has the ability to eat and survive on both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize the nutrients and energy of the sources absorbed. Often, they have the ability to incorporate food sources such as algae, fungi, and bacteria into their diet. Omnivores come from diverse backgrounds that often independently evolved sophisticated consumption capabilities. For instance, dogs evolved from primarily carnivorous organisms ( Carnivora) while pigs evolved from primarily herbivorous organisms (Artiodactyla). Despite this, physical characteristics such as tooth morphology may be reliable indicators of diet in mammals, with such morphological adaptation having been observed in bears. The variety of different animals that are classified as omnivores can be placed into further sub-categories depending on their feeding behaviors. Frugivor ...
