Uakari is the common name for the New World monkeys of the genus Cacajao. The Bald Uakari ( Cacajao calvus) also known as the Red Uakari or Bald-headed Uakari, is a distinctive red-faced monkey found in swampy Forests Chordates ( Phylum Chordata) are a group of Animals that includes the Vertebrates together with several closely related Invertebrates Mammals ( class Mammalia) are a class of Vertebrate Animals characterized by the presence of Sweat glands, including sweat glands A primate is a member of the biological order Primates ( Latin: "prime first rank" the group that contains Lemurs the Aye-aye The Pitheciidae are one of the four families of New World monkeys now recognised Pitheciinae is a subfamily of the New World monkey family Pitheciidae. René Primevère Lesson (March 20 1794 - April 28 1849 was a French surgeon and naturalist. In biology a type is that which fixes a name to a Taxon. Depending on the nomenclature code which is applied to the organism in question a type may be a specimen The Black-headed Uakari ( Cacajao melanocephalus) is a New World Primate from the Pitheciidae family (September 14 1769 &ndash May 6 1859 was a German naturalist and explorer, and the younger brother of the Prussian minister philosopher and linguist In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank.

The New World monkeys are the four families of Primates that are found in Central and South America: Cebidae, Aotidae, Pitheciidae A genus (plural genera from Γένος Latin genus "descent family type gender" is a low-level Taxonomic The common name is believed to come from the indigenous term for "Dutchmen"; their red faces apparently reminded the locals of sun-burned Europeans. Cacajao is also believed to be an indigenous name, of unknown meaning now, as the tribe and language is extinct.

The uakaris are unusual among New World monkeys in that the tail length (15-18 cm) is substantially less than their head and body length (40-45 cm). Their bodies are covered with long, loose hair but their heads are bald. They have almost no subcutaneous fat, so their bald faces appear almost skull like. Like their closest relatives the saki monkeys, they have projecting lower incisors. Sakis, or saki monkeys, are any of several New World monkeys of the genus Pithecia. Incisors (from Latin incidere, "to cut" are the first kind of Tooth in Heterodont Mammals They are located in the Premaxilla

The three species of uakari currently recognised are all found in the upper Amazon Basin. The Black-headed Uakari is found north of the river, between the Branco River and the Japurá River.

The Bald Uakari ( Cacajao calvus) also known as the Red Uakari or Bald-headed Uakari, is a distinctive red-faced monkey found in swampy Forests

Uakaris are typically lethargic and silent in zoo conditions, but in the wild they are agile and active, capable of leaps of over 6 metres. They have been observed both in small groups and in larger troops of up to 100. When travelling through the forest they move in the lower branches of the trees, though when foraging they also go up to the canopy. They eat fruit, nuts, buds and leaves.

Henry Walter Bates, the nineteenth century zoologist, recorded that the Native Americans captured uakaris alive by using blowpipe darts or arrows tipped with diluted curare; once captured the animals were revived by putting a pinch of salt in their mouths.
