Bald uakari (Cacajao calvus)

Like… what do I even need to say here? Apparently the bright red face indicates health to potential mates, making the monkeys think it’s hot I guess. They eat fruit and seeds, and are found in seasonally flooded forests of Peru.

Here’s my rendition of a descendant of the bald uakari (Cacajao calvus) known as the sisimito (Melanopithecus sanguinans), one of the future animals in my Splatoon headcanon! (In my headcanon, nearly all land mammals larger than a cat went extinct, but some smaller land mammals survived) Like its close relatives in the Calvopithecinae subfamily, it is robust in build and convergent with apes, which have been reduced to a few species in the mollusc era.

Northern Bald Uakari

Deep within the lush, untamed realms of the Amazon rainforest resides a creature of remarkable peculiarity and charm – the Northern Bald Uakari (Cacajao calvus rubicundus). This extraordinary primate, distinguished by its vivid red face, striking bald head, and haunting golden eyes, epitomizes the enigmatic biodiversity that thrives in the heart of South America. Despite its captivating…

[thing-a-ling]

I would like everyone to know I have unlocked a new fear in life. These things… Scientific name is the “Cacajao” commonly the Uakari, but can also be referred to as “the Englishman” due to the bald red face (sorry English people). Like no doubt they’re very polite, but sorry that’s a living nightmare creature. I am afraid.

「俺、結構酒強いよ。今日はとことん飲むよ」って誰も頼んでないのに宣言した人が、二杯目くらいに顔が「ウアカリ」みたいになってると、いつ吐くのか心配になっちゃって全然楽しめないからとにかく無理しないでほしい

飲み屋で確かにこんな顔の人いるｗ　このおサルさん初めて知ったけど、残念ながら日本の動物園にはいない模様。

Uakari

Genus: Cacajao

Particularly sinister looking, their name is not of the same ilk – meaning  ‘Dutchmen’ in the local language, this is said to be because their bright red faces reminded the locals of the sunburnt faces of European tourists.

Similar to Saki monkeys in the the food that they eat, they differ in how they move, as Uakaris can leap up to an astonishing 20 feet.

[is-the-primate-vid-cute]

Thoughts on uakari? I love how weird they look - like something from a dark fantasy movie :3

My thoughts are:

I LOVE THEM

They are so unique visually; They also have unique dentition that allows them to eat unripe fruits other Latin American monkeys can't eat!

Via Science Direct

90% of their diet consists of fruits and flowers. Their groups can consist of a pair up to hundreds of individuals; Larger groups are seen when food is more abundant. Groups are typically evenly divided male/female. Little is known about uakari as they have been studied very little in the wild. Captive troops are hierarchal but wild troops seem to be less strictly tiered. They wag their tail quite frequently and it is believed a lifted tail communicates excitement while a lowered tail communicates apprehension.

Cacajao calvus are the bald uakari, but

C. melanocephalus has plenty of hair

Little is known about their wild populations and their conservation status is not decided currently. Right now, they are listed as least concern but some believe the numbers are not accurate. They are targets of poachers for their skulls and body parts to sell to tourists, they are also captured for the pet trade. Threats to their habitat are of concern as well, like many tropical species.

The bald uakari (Cacajao calvus) or bald-headed uakari is a small New World monkey, native to the Western Amazon (Peru, Brazil and possibly Colombia). It normally grows to 14 - 22.5 in (35-57 cm), and weighs between 4 - 7 lb (1.8 - 3.2 kg). This primate is recognised by its short tail, bright crimson face, a bald head and long coat which range from blonde to orange to brown or red in color.

The striking scarlet red face is due to the blood flow under its facial tissue, specifically a thinner epidermis coupled with a higher concentration of capillaries in the face. While the female's face redness is associated with estrogen levels, that of the male's is indirectly related to his testosterone levels. Also, a redder face indicates a healthier monkey, which, similar to us humans, grows pale when the animal is ill.

Round 1, part 1, match 12: oddball monkeys

Gray-bellied night monkey (Aotus lemurinus)

Night monkeys are a rather odd group; while most monkeys are active in the daytime, night monkeys are nocturnal. Their huge eyes let them see even in the dark, and they have given up the colour vision otherwise common in monkeys. Gray-bellies are found in forests across the eastern edge of the Northern Andes. They eat mostly fruit, but also small animals.

Planned road to bisect pristine, biodiverse Brazilian Amazon national park

On the western edge of the Brazilian Amazon, a makeshift dirt road slices through dense rainforest. Along some stretches, the green canopy flanking the roughly-carved road gives way to open sky, felled trees and piles of neatly cut timber. It halts abruptly at the doorstep of Serra do Divisor National Park in Acre state, beyond which untouched forest sprawls over thousands of hectares to the Peruvian border.

The stretch of improvised road, which local sources estimate at roughly 20-30 kilometers in length, was carved out in recent months and appears to mark a first step in the construction of a proposed national highway project. When — or if — completed, it will stretch from Cruzeiro do Sul, in the Brazilian state of Acre, to the city of Pucallpa, in the Peruvian Andes.

The branch road — not yet officially approved by authorities — would extend the already lengthy BR-364, a highway that winds some 4,325 kilometers (2,687 miles) across Brazil, starting in São Paulo and currently ending in Acre. The new branch road would run another 152 kilometers (94 miles), cutting through Serra do Divisor, a national park federally protected since 1989 and known for its spectacular biodiversity.

The protected area spans some 846,633 hectares (2.09 million acres), and boasts thousands of plant and animal varieties, including threatened species like the White-uakari (Cacajao calvus calvus), a small New World monkey, and the Yellow-spotted river turtle (Podocnemis unifilis). Some, like the Acre antshrike bird (Thamnophilus divisorius) are relatively new to science (discovered in 1996); it is thought to be endemic only to Brazil’s Serra do Divisor and the adjacent Sierra del Divisor National Park in Peru.

Supporters of the new road tout it as a crucial commercial link, promising it will boost Brazil’s trade with its Andean neighbor and allow Brazil to more easily export products to Asia via Peru and the Pacific Ocean. But critics warn its construction will deal a devastating blow to the national park and the Indigenous people who call this untrammeled area home.

A key concern: The new highway will open up access to this remote portion of the Amazon rainforest as never before, potentially paving the way for a flood of loggers, cattle ranchers and landgrabbers into a mostly untouched region.
