When does a monkey turn down a free treat? When it is offered by a selfish person, apparently.
Given the choice between accepting goodies from helpful, neutral or unhelpful people, capuchin monkeys (Cebus apella) tend to avoid individuals who refuse aid to others, according to a study published today in Nature Communications.
The sounds of marmoset monkeys chattering may hint at the mysterious origins of human language.
A new study shows that marmosets exchange calls in a precisely timed, back-and-forth fashion typical of human conversation, but not found in other primates. The monkeys don’t appear to have a language, but the timing suggests the foundations of our own.
(WILDLIFE) FLORIDA — It started with three Rhesus monkeys, and now more than a thousand are living freely in the sunshine state. Because many of the animals are infected with the herpes-B virus, wildlife officials are now calling the monkeys a public health hazard—all because a tour guide snatched them from their home and brought them to Ocala, Florida to entertain tourists on his Jungle Cruise ride. Native to Asia, Rhesus monkeys are highly social and easily adapt to many habitats, including Florida. Only now, the little guys are being accused of terrorizing the state—just one more reason why we shouldn’t uproot wildlife for our own amusement.

With its long nose, the Proboscis Monkey is certainly one of the most easily identifiable Old World monkeys, with its reddish hued coat adding a certain unique physical trait to its already stand out characteristics.
Found in Borneo, it is also known as the bekantan, and is also even popularly referred to as the orang belanda or the “Dutchman”, as well as the monyet belanda or “Dutch Monkey”, namesakes which owe their origins to how the people of the Southeast likened the monkey’s large bellies and long noses to those of Dutch colonizers.
Known for being among the largest of monkeys found in Asia, the Proboscis Monkey’s nose is so unusually large that they have been described as “living caricatures”, with most caricatures typically exaggerating physical attributes such as large eyes, large ears and large noses.
With the average Proboscis Monkey measuring somewhere between 21 to 76 inches in head to body lengths, they are known to weigh as small as 15 lbs to as much as 50 lbs.
The nose of the Proboscis Monkey, particularly in males, can grow in lengths of up to 4 inches, typically hanging lower than the monkey’s mouth. Though the noses of female Proboscis Monkeys aren’t as long as those found in males, they are still quite long for a monkey to have.
Also, apart from their long noses, both male and female Proboscis Monkeys have “pot bellies”, which essentially makes them appear more “human like”, to a certain extent.
Primarily, Proboscis Monkeys partake on diets mostly made of fruits and leaves, but they are also known to feast on small insects and flowers from time to time. As with most monkeys, they also have their own set of natural predators, which includes crocodiles, clouded leopards, and pythons.
Classified as an Endangered species, Proboscis Monkeys are certainly among the stranger and more unique monkeys in the world, with their long noses giving them an uncanny look that is somewhat similar to the faces of human beings.
The White-faced Saki Monkey is one of the different types of monkeys of the Pithecia genus, which is categorized as a member of the New World Monkey order.
Found in the Northern and Central areas of South America, Saki Monkeys are found in different parts of the South American continent including Peru, Colombia and the Northern portions of Bolivia, with the White-faced Saki Monkey found in Brazil.
Characterized as a small monkey that is built for arboreal habitats, the White-faced Saki Monkey is defined by a head that is “hooded” with fur, a physical characteristic that has led its naming to be so. Also found in Guyana, Suriname, Venezuela and in French Guiana, the White-faced Saki Monkey’s looks has also led many in referring to them as the Golden-faced Saki.
As a species, the White-faced Saki Monkey is known to spend a lot of time atop trees, mostly in the lower canopies of forests. With a diet that is dominated by fruits, they are also known to consume quantities of different seeds and nuts, as well as having a certain penchant for feeding on small insects.
One unique trait found in White-faced Saki Monkeys is in how their “mating rites and rituals” are setup, with White-faced Sakis typically mating with only one partner for life.
As with most male and female mammals, physical differences between male and female White-faced Saki Monkeys are known to be present, with most male White-face Sakis sporting dark-black hued coats which are complemented with a reddish-white hued tone on their face, throat and forehead. Females are known to sport a lighter hued coat, typically brownish grey, which is matched with brown stripes located in the ends of their eyes and mouth.
Being native to the forests of Central America, the White-faced Saki Monkeys are not an endangered species. Different types of Sakis are known to be kept in captivity, with further studies and understanding devoted to the species being given their due.
With their small physiques and their distinct “hooded” faces, the White-faced Saki Monkey is truly an interesting monkey that stands out from the rest.
As a member of the tamarin species, the Emperor Tamarin is known to stand out due to one of its subspecies’ bearded chin forms, but its black-chinned subspecies is also known to have its own unique set of Emperor Tamarin traits and characteristics.
Found in the eastern portions of Peru, west of the Amazonas and Acre in Brazil and north of Bolivia, the Emperor Tamarin is essentially native to the Southwestern Amazon Basin, with its name alleged to have been taken after Emperor Wilhelm II of Germany, who is described to mirror the general looks of Emperor Tamarins.
With body lengths that measure as much as 9 to 10 inches, the Emperor Tamarin’s tail is known to grow as long as 14 inches, with the average weight of an Emperor Tamarin measuring somewhere around 300 to 400 grams.
Sporting a grey-hued coat that is matched with yellowish spots on its chest, it is the Emperor Tamarin’s beard which really stands out, which is generally white hued and typically growing long enough to lengths which go beyond its shoulders.
Typically found deep in rain forests, the Emperor Tamarin spends a lot of its time up on trees, known to be diurnal with the ability to walk or run on its four limbs. Like most tamarins, they live in groups typically consisting somewhere between two to eight members, and are even known to take in other tamarins species like the Brown-Mantled Tamarin as members of certain groups.
One interesting thing about Emperor Tamarin groups, apart from the fact that they aren’t “exclusive” only to Emperor Tamarin species, is that it is the oldest female that stands as a group’s leader, not the male.
Also, apart from their unique group hierarchy setup, Emperor Tamarins are known to have their own set of “cries”, each set to effectively identify potential threats and dangers.
Smart and highly organized, the Emperor Tamarin truly stands out as one of the world’s unique creatures of the jungle.
