Endemic Animals of Amazonas

The Pied tamarin (Saguinus bicolor) is a Critically Endangered primate species found in a restricted area of the Brazilian Amazon Rainforest. It was named the mascot of Manaus, Brazil in 2005. Less

The predicted antwren (Herpsilochmus praedictus ) is an insectivorous bird in the antbird family Thamnophilidae. The predicted antwren was first described in 2013. The name refers to the fact that the bird was predicted to be a separate species on the basis of its distinctive vocalizations, which was later confirmed by analysis of its mitochondrial DNA.It is found in Amazonian Brazil.

Bachia panoplia is a species of lizard in the family Gymnophthalmidae. It is endemic to Brazil. Less

The black squirrel monkey (Saimiri vanzolinii ), also known as the blackish squirrel monkey or black-headed squirrel monkey, is a small New World primate, endemic to the central Amazon in Brazil. It largely resembles the female of the far more common Bolivian squirrel monkey, though the latter lacks the black central back.This squirrel monkey has one of the most restricted geographical distributions for a primate, living in várzea forest in the ...
confluence of the Japura and Solimões rivers. Its entire range is within the Mamirauá Sustainable Development Reserve. It resides in the reserve with two other Saimiri species. It is a social primate that travels with other black squirrel monkeys in large troops within its habitat. Its small size makes it an easy target for its predators; however, it may resist predators when it travels in large troops.Its species overall has positive effects on the economy. Less

The Roosmalens' dwarf marmoset (Mico humilis ), also known as the black-crowned dwarf marmoset, is a small New World monkey native to the Amazon Rainforest, on the east bank of the lower Madeira River, and the west bank of the Aripuanã River, in Brazil. It has the smallest distribution of any primate in Amazonia. This marmoset has several unique attributes, which has resulted in it sometimes being placed in the monotypic genus Callibella. ...
However, genetic analysis has subsequently resulted in its being classified within the genus Mico.It was first described in 1998, after it was discovered ca. 400 km (250 mi) south of the city of Manaus. In 1996, Marc van Roosmalen, the discoverer, was given a milk can by a river trader with one of these monkeys inside. He suspected it was a new species, a relative of the pygmy marmoset, but at that point was unaware of its exact origin. Following a lengthy expedition, it was discovered near the town of Nova Olinda in southeastern Amazonas. The species has been subsequently recorded further south, along the west banks of Rio Roosevelt.Adult Roosmalens' dwarf marmosets have a total length of 38–39 cm (15-15½ in), incl. a tail of 22–24 cm (8½–9½ in), and weigh 150–185 g (5½–6½ oz). It is the second smallest species of monkey, with only the related pygmy marmoset being smaller. The upperparts of Roosmalens' dwarf marmoset are mainly dark olive-brown, while the underparts are pale, dull yellowish. The bare, pale pinkish face is bordered by a whitish ring of hair. The crown is blackish, as suggested by its alternative common name; black-crowned dwarf marmoset. It has claws as opposed to nails, like other marmosets who feed off tree sap. It also has teeth similar to other marmosets.It is considered unusual among marmosets in that it gives birth to only a single baby instead of twins, the norm for marmosets. Marmosets are often very territorial, though this is not the case among Roosmalens' dwarf marmoset, where it is common for multiple females in a group to have young, instead of one dominant female.

The black-headed marmoset (Mico nigriceps ) is a marmoset species endemic to Brazil. It inhabits humid tropical rainforest, mostly second growth and edge; the distribution is not exactly known but is thought to be Rio dos Marmelos in the north and east, Madeira River in the west and Ji-Paraná River in the south.

The Amazon black howler (Alouatta nigerrima ) is a species of howler monkey, a type of New World monkey, endemic to the south-central Amazon in Brazil. Until 2001, most authorities included it as a subspecies (or simply a taxonomically insignificant variation) of the red-handed howler, though its distinction had already been pointed out much earlier. As suggested by its name, it typically appears entirely black. Less

The Marca's marmoset (Mico marcai ) is a species of marmoset that is endemic to the Amazon, in the Aripuanã-Manicoré interfluvium in Brazil. Its body is light grey, with orange legs, a black tail, a pinkish face, and naked ears. It is about 9 inches (23 cm) long, excluding the tail, and it has a 15-inch (38 cm) long tail. It weighs about 12 ounces (340 g).It was previously thought to be virtually unknown; in 2008 the IUCN noted that it had never been ...
seen in the wild, though it has been observed since then. However, later studies found the Manicore marmoset (Mico manicorensis ), discovered in the Campos Amazônicos National Park in 2000, to be conspecific with M. marcai, and thus both were synonymized. Less
