Monkeys, with their wide range of shapes and sizes, exhibit a captivating diversity. These medium-sized, long-tailed primates belong to the primate family, along with macaques, baboons, guenons, capuchins, marmosets, and tamarins, encompassing a total of 264 recognized species. It’s important to note that despite their physical resemblance, chimpanzees and apes are not classified as monkeys in scientific terms.

Monkeys can be categorized into two groups: New World monkeys and Old World monkeys, distinguished by the presence or absence of prehensile tails. The New World monkeys possess this remarkable trait, allowing them to grasp and manipulate objects, while the Old World monkeys lack prehensile tails altogether.

Within each monkey group, there are distinctive facial features that set them apart, yet they also share common characteristics. Their sizes vary significantly, ranging from the diminutive 5 to 6-inch Pygmy Marmoset to the towering adult male Mandrill, which can reach a height of 3 feet. 

While some monkeys spend their lives predominantly in treetops, others inhabit savannas and grasslands. To sustain themselves, most monkeys consume a diet consisting of fruits, leaves, nuts, berries, eggs, and insects. Occasionally, they display hunting behavior, targeting smaller prey.

The world of monkeys offers an intriguing tapestry of biodiversity, showcasing their adaptations and behaviors across different habitats.

Humans and Monkeys

Ugly Monkeys Species

Looking back at our evolutionary history, it’s fascinating to realize that humans and modern apes share more than just a few similarities. We actually have a common ancestor with older iterations of ape-like animals, and we diverged from them millions of years ago. But here’s the interesting part: we didn’t descend from chimpanzees or gorillas, but rather in tandem with them – it’s almost like we took different paths while evolving. 

As a result, in terms of primates, humans are only a species of giant ape with no hair. It’s remarkable to consider that although we’ve evolved into something very different from our early ancestors, we still have 98 percent of our DNA in common with chimpanzees and bonobos.

Various Types Of Monkeys

Monkeys can be classified into two main families: Old World monkeys and New World monkeys. Old World monkeys are primarily found in Asia and Africa, distinguished by their downward-pointing noses. On the other hand, New World monkeys inhabit North and South America, characterized by their outward-pointing nostrils.

Each group possesses unique adaptations and abilities. Notably, certain New World monkeys, like South American spider monkeys, boast prehensile tails that allow them to grip and manipulate tree branches and objects. In contrast, many Old World monkeys have cheek pouches where they can store food for later consumption.

Monkeys display a remarkable diversity in appearance. For example, male probosci’s monkeys from Borneo, Southeast Asia, are renowned for their large noses. A study published in the journal Science Advances revealed that these monkeys utilize their impressive noses to attract female partners, as longer noses are preferred by females. 

Furthermore, their prominent nostrils enhance their vocalizations. Proboscis monkeys feature pot-bellied bodies and crimson cheeks, presenting a striking contrast to other species such as the slender and small-nosed black and brown spider monkeys.

The world of monkeys captivates with its array of physical attributes and adaptations, showcasing the wonders of evolutionary diversity.

Monkeys Considered the “Ugliest”

Monkeys are fascinating creatures, with their clever intellect and playful demeanor. However, not all monkeys possess an attractive appearance. In fact, some could be regarded as downright ugly. From the hairless baboon to the malformed proboscis monkey, these five species represent some of the most peculiar-looking primates found around the globe. 

Despite their unattractive appearance, these monkeys remain captivating creatures that deserve further study. As the famous African proverb states, “No matter how you fix a chimpanzee’s nose, it’s still ugly.” Let’s take a closer look at these peculiar primates and what makes them some of the ugliest monkeys in the world.

#1 Bald Uakaris

Bald Uakaris

 In the vast expanse of the Amazon rainforest, one can find a particular species of monkey known as the bald uakari. These monkeys stand out with their distinct features, including bald, scarlet cheeks and tufted whitetails. While their appearance may strike us as unusual, their red, hairless visage is actually a sign of vitality and good health. It’s quite remarkable to encounter a monkey with long, shaggy fur alongside a vibrant red face.

Bald uakaris with their exposed heads are often relatively small, measuring approximately 12 inches in body length. They typically weigh between two to four pounds, with males tending to be larger than females. Due to the intricate network of blood vessels near the surface of their skin, they are sometimes referred to as “scarlet fever uakaris.”

Sadly, bald uakaris are considered vulnerable in terms of their conservation status. However, there is reason for hope, as various initiatives are already in place to protect and preserve these unique and remarkable creatures.

The bald uakari monkeys serve as a testament to the diverse and captivating wildlife that thrives within the Amazon rainforest, reminding us of the importance of conservation efforts to ensure their continued existence.

#2 Proboscis Monkey

Proboscis Monkey

Among the world’s most peculiar and visually striking primates is the probosci’s monkey. With its distinctive feature of a broad and bulbous snout, it stands out effortlessly. The male probosci’s monkey boasts an astonishing nose, which can reach up to 7 inches in length, and it utilizes this elongated feature to captivate and attract females. Interestingly, the females possess much smaller noses. While we may perceive this monkey as unattractive, it’s undeniable that within their own species, their distinctive noses are considered quite appealing.

Originating exclusively from Borneo, probosci’s monkeys have made this region their sole natural habitat. They are known to take to the water to evade predators, displaying impressive swimming abilities. These remarkable creatures are found in the lush mangrove forests near rivers, particularly in swampy areas.

 Their diet primarily consists of leaves, fruits, and seeds, with insects playing a less significant role. Unfortunately, the wild population of probosci monkeys is estimated to range from only 2,000 to 5,000 individuals, emphasizing the urgent need to raise awareness and prevent the extinction of this species.

The probosci’s monkey’s unconventional appearance and distinct ecological niche make it a captivating subject for conservation efforts. By shining a spotlight on these unique primates, we can work towards ensuring their survival and preserving the biodiversity of their precious Bornean habitat.

#3 Spider Monkey

Among the myriad of peculiar monkeys found across the globe, one species stands out as possibly the most extraordinary—the spider monkey. With their long, slender limbs and tail that resemble those of an alien creature rather than a conventional animal, these tiny creatures from South and Central America exhibit an otherworldly appearance. However, beyond their unsettling looks, spider monkeys possess captivating qualities that make them truly fascinating.

Spider monkeys exhibit exceptional agility, utilizing their elongated tails as a fifth limb to effortlessly swing through the trees. Their limb-like tails grant them the ability to traverse between tree branches with unparalleled ease. 

In fact, they are one of the few monkey species capable of both walking on all fours and swinging through the forest canopy, making them equally adept on the ground and at the heights of the jungle. While their physical prowess is remarkable, it is their intelligence that truly sets them apart.

These remarkable creatures demonstrate a level of intelligence that is highly distinctive. Spider monkeys have been observed using tools, such as branches or leaves, to scratch themselves or to aid in foraging for food. This remarkable behaviour showcases their adaptability and problem-solving abilities.

Undeniably, spider monkeys possess a unique charm, despite not conforming to conventional notions of cuteness. Their alien-like appearance and extraordinary behavioural traits make them a captivating subject of study and admiration. Embracing the diversity of the animal kingdom, spider monkeys serve as a reminder of the endless wonders and surprises that nature has to offer.

#4 Red-Faced Spider Monkey

Red-Faced Spider Monkey

The red-faced spider monkey may be considered unattractive or even bizarre in appearance. Its elongated limbs and tail bear a striking resemblance to those of a spider, hence its name. With its crimson face and peculiar anatomy, this creature appears more like an otherworldly being than a typical monkey. However, its unconventional looks should not be seen as a weakness, but rather as a unique strength.

The spider monkey’s distinguishing features grant it remarkable agility, particularly when navigating through trees. Its long, flexible tail serves as a fifth limb, allowing it to effortlessly swing from branch to branch. Additionally, its anatomical structure facilitates seamless movement on land. The spider monkey’s unusual appearance is a testament to its adaptability and versatility in different environments.

Beyond its physical attributes, the spider monkey possesses a sophisticated intellect. Despite its peculiar appearance, it harbours a keen mind, which is an admirable trait. One example of its intelligence is its ability to create and use tools for various purposes, showcasing problem-solving abilities and resourcefulness.

While the red-faced spider monkey may not conform to conventional standards of beauty, its uniqueness should be celebrated. Its odd appearance is accompanied by remarkable physical capabilities and intellectual prowess. By embracing the diversity and extraordinary characteristics of this species, we gain a deeper appreciation for the wonders of nature and the fascinating creatures that inhabit our world.

#5 Tarsier

Tarsier

Among the diverse array of monkey species across the globe, few captivate our attention quite like tarsiers. Found in Southeast Asia, specifically in countries like the Philippines, Indonesia, and Malaysia, these diminutive primates possess a distinct charm that sets them apart. With their unique traits and fascinating behaviours, tarsiers leave us in awe.

Tarsiers are creatures of the night, thriving under the cover of darkness. Their nocturnal nature sets them apart from their diurnal counterparts. As carnivorous monkeys, they have a specialized diet consisting mainly of insects, making them one of the rare completely carnivorous monkey species in the world.

What immediately catches the eye when observing tarsiers is their extraordinary eyes. Despite their small size, their eyes are disproportionately large, accounting for approximately 75% of their head. While one might assume that these massive orbs provide them with superior vision, tarsiers actually face challenges in daylight. Consequently, they are most active during the night, when their eyes can adapt more effectively to low-light conditions. Additionally, tarsiers possess long, muscular legs, enabling them to perform remarkable leaps of up to six feet into the air.

Though their appearance may seem otherworldly and unconventional, tarsiers possess a captivating allure. Their unique features and behaviours contribute to their intriguing nature. So, the next time you encounter a tarsier, take a moment to appreciate its extraordinary qualities and immerse yourself in the wonder of these remarkable creatures.

#6 Chacma Baboons

In the vast landscapes of Southern Africa, one can encounter the distinctive chacma baboon, known for its rather unattractive appearance among its baboon relatives. While mandrills boast luxurious fur and vibrant, eye-catching faces, the chacma baboon’s plain brown fur fails to captivate. With sharp canines, prominent snouts, and angular facial features, they have earned the nickname “dog-faced monkeys.”

Adding to their peculiar traits is the crimson or blue colouration of their rear ends, which can be quite discomforting to observe. The reasons behind this unique characteristic are still subject to debate and speculation. Some propose that the colourful rear end acts as a visual signal to attract potential mates, while others suggest it may serve as a form of visual communication within the baboon community.

Regardless of the underlying cause, there is no denying that the chacma baboon holds a distinct position among the world’s ugliest primates. Its plain appearance and colourful posterior make it an intriguing and somewhat unconventional member of the primate family.

While beauty may be subjective, the chacma baboon’s distinctive features certainly make it an intriguing addition to the rich diversity of primates found in Southern Africa.

#7 Golden Snub-Nosed Monkey

Golden Snub-Nosed Monkey

The golden snub-nosed monkey is a unique species that call the chilly regions of forests and mountains home. Unlike other animals, their snub noses are the only visible feature on their faces, which biologists suggest is due to the freezing temperatures in their habitat. 

These intelligent primates are the only species of monkey that can survive the harsh winter conditions that plummet to a frigid 18-25 degrees Fahrenheit. Interestingly, biologists suggest that a more noticeable nose would freeze in the cold, hence the practical design of their snub noses. With such an awe-inspiring adaptation, it’s no wonder the golden snub-nosed monkey thrives in their frosty habitat.

#8 Hamadryas Baboon

Hamadryas Baboon

Among the baboon species, the Hamadryas baboon stands out as one of the most aggressive and unappealing. When it comes to their females, male hamadryas baboons display extreme possessiveness, refusing to tolerate any signs of disloyalty. 

If a female strays or shows affection towards another male, the dominant male reacts by biting her and issuing visible threats. Troops of Hamadryas baboons can consist of hundreds of individuals, organized into smaller groups within the larger unit. Each group comprises a dominant male, his harem of females, their offspring, and subordinate young males.

Originating from regions such as Somalia, Ethiopia, Djibouti, Eritrea, Saudi Arabia, and Yemen, these baboons inhabit the Horn of Africa. They thrive in diverse habitats such as savannas, rocky terrains, and arid grasslands. Seeking safety, they often take refuge in the shelter of rocky cliffs. As omnivores, their diet varies depending on the season. 

During the dry season, they feed on sisal and Dobera Glabra leaves. In the wet season, when the soil is teeming with life, they consume flowers, grasses, roots, seeds, as well as the bark and leaves of acacia trees. Throughout the year, they supplement their diet with small animals, birds, insects, and reptiles.

While hamadryas baboons may not possess the most endearing qualities, their tenacity and adaptability to diverse environments make them a remarkable species in their own right.

#9 Stump-Tailed Macaque

Stump-Tailed Macaque

The bear macaque, also known as the stump-tailed macaque, sports a dense coat of fur covering its body, while its face remains hairless, and its tail is notably short and stumpy. As these macaques age, their reddish-pink faces darken over time and may eventually turn entirely black. Similar to other macaque species, they possess cheek pouches used for storing food. Their natural habitat spans moist, evergreen forests in southern China, west Malaysia, Thailand, Vietnam, and the Malay Peninsula. However, it is worth noting that the Himalayan region in northern India hosts the only population that does not dwell within its native forest habitat.

Distinguishing themselves from other macaques, bear macaques possess robust, muscular bodies that are better adapted for terrestrial living rather than tree-climbing. While fruits constitute an important part of their diet, they consume a greater proportion of eggs, insects, and small animals compared to other macaque species. Known for their calm demeanour, instances of aggression among bear macaques are typically brief and uneventful.

The bear macaque stands as a unique primate species, with its distinctive physical features and dietary preferences, offering a fascinating glimpse into the diversity of the animal kingdom.

#10 Crab-Eating Macaque

 Crab-Eating Macaque

Crab-eating Southeast Asian-born macaques are fascinating primates that are known for their diving skills in the mangrove wetlands. These long-tailed macaques display a versatile diet that includes crabs, fruits, seeds, bark, flowers, leaves, and roots. While consuming various types of seeds, they have developed a rather curious habit of spitting out those larger than 0,1 – 0,15 inches. 

This behaviour suggests that they are capable of avoiding indigestible seeds deliberately. Other than mangrove swamps, these macaques are found in forests, shrublands, and also near human habitats such as cities and villages. Although they are fascinating to watch, they are known to grab food passively and forcibly in urban settings, making them a nuisance to locals.

How Memes Helped The “Ugly Monkeys”

A recent study conducted in Poland aimed to shed light on strategies for generating public interest in protecting less visually appealing species, such as the probosci’s monkey. Researchers delved into the effectiveness of sharing humorous online memes featuring the monkey, accompanied by text that connected its appearance to Polish jokes and cultural references. 

These memes were disseminated through social media and conservation marketing channels, with the goal of boosting public engagement in safeguarding this oddly unattractive primate. To gauge the impact, the scientists compared public donations to conservation projects, tracking the popularity of probosci’s monkeys against more iconic and cute species like koalas and gorillas.

The initiative proved to be a game-changer, as the probosci’s monkey garnered significantly more media attention than other typical conservation species, which had previously been virtually unknown in Poland. The circulation of humorous memes highlighting the monkey’s comical appearance sparked numerous grassroots crowdfunding campaigns dedicated to funding its conservation in Borneo. Surprisingly, these initiatives received contributions from a total of 218 individuals.

The overall outcome was remarkable, transforming a species that had been overshadowed into a focal point of substantial attention. This newfound spotlight ultimately played a crucial role in securing the necessary funds to preserve the monkey’s habitat. These findings suggest that conservationists should dare to be innovative, harnessing the power of memes to raise awareness and secure vital resources for the most underappreciated endangered creatures within the animal kingdom.

Myths

Daubentonia madagascariensis, commonly known as the aye-aye lemur, serves as another striking example of how public perception can impact conservation efforts. In contrast to the plump and flabby appearance of the probosci’s monkey, the aye-aye possesses a slender and unkempt physique with large, bug-like eyes. 

Its prominent front incisors resemble the teeth of Nosferatu, adding to its peculiar look. Furthermore, its elongated middle finger is remarkably long and serves the purpose of extracting grubs from trees (or, according to Malagasy legend, casting curses upon unsuspecting humans). 

Even the name “aye-aye” is a linguistic ploy, imitating the creature’s unique vocalizations to avoid direct nomenclature.

Unfortunately, despite the species’ unjust reputation as harbingers of doom for humans, it is human actions that pose the greatest threat to the aye-aye’s survival. The population of aye-ayes has significantly declined since the 1980s, primarily due to hunting, habitat destruction, and persecution driven by cultural beliefs associating them with “evil.”

In a recent study conducted by researchers from Madagascar and Germany, it has been discovered that the Makira region in northeastern Madagascar holds promise as a potential stronghold for aye-aye conservation. Contrary to previous beliefs that negative perceptions of aye-ayes were widespread throughout Madagascar, this particular region exhibits more positive attitudes towards these unique creatures.

In areas where negative attitudes prevail, villagers often struggled to identify aye-ayes in photographs, perceiving them as unsettling and even mythical threats. However, the study found that individuals who had a better understanding of aye-aye behaviour held more positive opinions of the species. In particular, those who recognized the aye-aye’s role in controlling insect infestations on vital crops viewed them in a favourable light.

The findings highlight the importance of knowledge exchange as part of a comprehensive conservation strategy and shed light on the potential to influence deep-seated attitudes. By fostering firsthand experiences and promoting awareness of the valuable contributions aye-ayes make to local ecosystems, it is possible to cultivate positive attitudes and support for their conservation.

Final Words 

Monkeys are fascinating creatures that are a part of the primate family. Although chimpanzees and apes may look like monkeys, they are separate classifications of primates. It is interesting to note that humans are descended from a specific type of ape, but we are not apes ourselves; rather, we share 98 per cent of our DNA with chimpanzees and bonobos. 

Monkeys can be categorized into two groups – New World and Old World – with each group possessing unique characteristics like prehensile tails or pouches. However, there are a few species of monkeys that may not be conventionally aesthetically pleasing, such as Bald Uakaris, Proboscis Monkeys, Spider Monkeys, and Red-faced monkeys. Despite this, monkeys remain a captivating aspect of the animal kingdom that continues to intrigue and inspire people’s curiosity.
