Yes, monkeys have nails, much like humans do. They have both fingernails and toenails on all their digits. Monkeys also have claws – sharp, curved claws on their fingers and toes that help them grab onto things.
The claws are mainly adapted for gripping, climbing, and hanging on branches. Monkeys’ claws differ in a few notable ways from other species. For example, the claws of some species of monkeys are flattened, much like a human fingernail, while others are more curved and hooked.
Despite their differences, both types of claws provide adhesive properties and aid in movement.

Which monkeys have claws instead of nails?
New World Monkeys typically have claws instead of nails. These monkeys, which belong to the family of Platyrrhini, are found in Central and South America, and in parts of Mexico and Central America. The most common types of New World Monkeys are Howler Monkeys, Spider Monkeys, Titi Monkeys, Capuchin Monkeys, Marmosets and Tamarins.
These monkeys have grasping hands and feet, and their thumbs and big toes have a flat nail. Unlike most other primates, New World Monkeys have only two toes that have claws, which they use for gripping tree branches and other objects.
Old World Monkeys, which are found in Africa and parts of Asia, generally have nails instead of claws.
Do orangutan have claws or nails?
Orangutans have both claws and nails. Rather than true claws, the orangutan’s hands and feet possess flattened nails which curve into a hook-like shape, allowing them to grip and climb better. These semi-curved nails are more like a hoof than a true claw and are made of keratin with a soft, leathery outer covering of epidermis called the cuticle.
The nails on the orangutan’s toes are thick and curved, while their hands possess long, flat nails on their fingers. In addition to their nails, orangutans also have long, fine hairs on their palms and fingers which are used to tactilely feel surfaces, helping them to manage more complex grip and climb motions.
Do gorillas have to cut their nails?
Similar to humans, gorillas do have to cut their nails. While gorillas’ nails generally wear down naturally due to their forest habitats and activities, occasionally the nails may need to be trimmed to keep them at appropriate length.
Gorillas have long-fingered hands with curved nails that are especially adapted for their diet and lifestyle of climbing, swinging and foraging for food. When their nails become too long, it can be difficult for them to perform these activities.
For the health and comfort of gorillas, experts may need to trim their nails when necessary.
Trimming a gorilla’s nails is typically a job for professionals such as veterinarians and animal keepers, as it requires specialized equipment and knowledge. During the process, the gorilla may need to be sedated or receive anesthesia to ensure their safety and comfort.
After the nails have been trimmed, the expert will likely also bandage or dress the wound to protect it from infection.
How do gorillas keep their nails short?
Gorillas use their hands and feet to climb and swing through the trees and vines that provide them with food and shelter. As a result, they have developed strong and agile nails that help them to grip and hold onto branches and trees.
To keep their nails neat and short, they will use the rough bark of trees to naturally file them down. Additionally, they may also use objects in their habitat such as rocks and large stones to naturally wear down the length of their nails.
Lastly, they may also rub their nails against things like vines or large tree roots to help keep their nails short and well maintained.
Can a chimpanzee hurt a human?
Yes, chimpanzees are physically capable of hurting a human. Although they are not normally aggressive toward humans, they are physically much stronger than the average person and can be quite aggressive if provoked or frightened.
Reports of chimpanzees attacking and biting humans, even causing fatalities, have been recorded in the wild and in captivity. The most famous example was a chimpanzee named Mickgee, who attacked and nearly killed a woman in Connecticut in 2009.
It is important to remember that chimpanzees are still wild animals and should be treated with respect and caution. They should not be kept in captivity as pets and people should be careful to not approach a wild chimpanzee.
Do chimps have fingers and toes?
Yes, chimpanzees have fingers and toes. Chimpanzees have five digits on each hand, including a thumb and four fingers. They also have five digits on each foot, including a big toe. In this way, their hands and feet look almost like human hands and feet.
However, there is an important difference. Chimpanzees walk on their knuckles with their fingers and the long, curved fingers support the knuckle walking. In contrast, humans walk on the flat sole of their feet.
This means that humans do not use their fingers or toes to support or help during walking.
How hard can a chimp hit?
Chimpanzees are incredibly strong and can produce a powerful bite force of up to 950 pounds per square inch (PSI). This is sometimes compared to the force of a large hammer or a golf club. The powerful jaw muscles of a chimp coupled with their large, flat molar teeth are an adaptation that allows them to bite hard objects with effective force.
This makes a chimp’s bite more powerful than that of a human, which is typically around 200 PSI. In fact, the force of a chimpanzee bite is enough to break through a human’s skin.
However, chimps also have the ability to modify their behavior in order to control how hard they bite. This means they can hit things as hard or as soft as they want to. So, while a chimp can hit very hard, they can also hit very lightly depending on circumstance.
Why did primates lose claws?
Primates, including humans, evolved from ancestral primates that had claws. Over time, primates developed adaptations that allowed them to use their hands and fingers in new ways, specifically for manipulating objects and for climbing.
These adaptations included the loss of physical claws and the gain of opposable thumbs and long, curved digits.
The loss of claws enabled primates to be able to grasp and manipulate objects more adeptly, which likely allowed for the development of complex manipulative behaviors, such as tool use and object construction.
There is also evidence that primates may have used their hands and fingers to climb in the trees, rather than relying solely on claws like their ancestral counterparts. These advantages may have provided an evolutionary advantage over other animals, and so primates evolved to rely on the manipulation of objects rather than the use of claws.
The use of tools and manipulation of objects were critical steps in human evolution, and so the loss of claws likely played an important role in our success as a species. Claws may still be present on certain primates, such as some lemurs or tarsiers, but they are not as prominent as they once were in the ancestors of modern primates.
When did humans start cutting their nails?
The exact date of when humans began cutting their nails is unknown, but archaeological evidence suggests that it has been done since the Bronze Age (from c. 3300 to 1200 BC). Pottery shards from Ancient Egypt depict figures with manicured nails, and there is evidence that fingernail and toenail trimming was a common grooming practice in many ancient cultures.
The ancient Babylonians and Assyrians used metal clippers to cut and shape their nails, while the Chinese invented an early form of what we today call nail scissors. These nail clippers were made of silver and were often adorned with intricate designs.
By the Middle Ages, nail cutting had become common practice even among the lower classes, as it was seen as a sign of good hygiene. In the 19th century, the invention of the nail file and the modern nail clipper made it easier to take care of nails and the practice became widely accepted.
Why do humans not have tails?
Humans do not have tails largely due to the process of evolution which led to their current state. As humans evolved from their primate ancestors millions of years ago, they underwent many changes that allowed them to better adapt to their environment.
During this process, tails were no longer deemed necessary and eventually disappeared. This is likely because they ceased to be useful and eventually hindered our ability to perform activities like walking upright and negotiating obstacles in our environment.
Furthermore, the lack of a tail helped us to develop more balanced posture, which allowed us to move more efficiently and use our hands to manipulate objects and our environment. Therefore, the general trend in evolution is that humans moved away from having tails due to their lack of evolutionary value.
What is the difference between claws and nails?
Claws and nails have a lot of similarities, as they are both horn-like proteins that grow from the skin of the fingers and toes. However, they are structural, functional and compositionally different.
Claws are curved and usually sharper than nails. Claws are thicker than nails and can be used for grasping and tearing objects, while nails are thin and primarily used to aid in gripping. Claws are hooked and also contain a layer of hard keratin, while nails have a hard, flat surface with no curve or hook.
Claws have a base that is comprised of several layers of epidermis, while nails have no basal layer. Additionally, the lunula, or crescent-shaped white area of the nail, is absent from claws. Finally, claws are not typically trimmed, whereas nails are manicured.
Did fingernails evolve from claws?
No, fingernails did not evolve from claws. Claws are derived from an ancestral group of animals known as therapsids, which lived around 300 million years ago. Fingernails, on the other hand, evolved millions of years later as primates, who are descended from therapsids, developed and adapted to their environment.
Specifically, scientists believe that fingernails evolved to help primates climb and hold onto branches with more precision and strength. This adaptation allowed primates to use their fingernails as a tool to help them survive and thrive.
Over time, fingernails became more pointed and curved, which offered more protection and could be used as defensive and offensive weapons in certain circumstances. Ultimately, this helped our ancestors survive and pass on their genes.
While there is no direct evolutionary link between claws and fingernails, both are adaptations that served to help animals thrive in their particular environment.
