Monkeys, like all primates, have fingernails to support their fingertips. Nails are wide, flat, and shield-shaped, and they are located at the back of the fingertips. This shape and location make it easier for monkeys to grasp objects and climb trees. Monkeys' nails also help them scratch and separate objects, and protect their fingers from viruses and bacteria. While long nails can impede their ability to perform certain tasks, such as picking off insects during grooming, monkeys have been observed using various methods to keep their nails trimmed, including biting them or simply waiting for them to break off on their own.

What You'll Learn
Monkeys' fingernails help them climb trees
Monkeys, like all primates, have fingernails. These nails are present to support their fingertips. Fingernails are made up of three layers of tissue called keratin, which is a type of tissue that has amino acid proteins. This hard, outer covering on the tips of the fingers makes the fingertips one of the strongest parts of the hand, which is useful for climbing trees. The nails also have many small blood vessels supplying them, and they can maintain their blood flow even when the monkey is gripping something very tightly, such as a tree branch.
Monkeys' fingernails also help them climb trees by enhancing their ability to grip and separate objects, such as bamboo shoots or insects during grooming. The nails make the fingertips more rigid, which is useful for scratching and performing other fine motor movements.
In addition to aiding in climbing trees, monkeys' fingernails also provide protection. The nails act as a covering that can prevent viruses and bacteria from entering the body. While monkeys do not have access to manicures or nail clippers, they have been observed using various methods to keep their nails trimmed, such as biting them or waiting for them to break off naturally. Therefore, monkeys' daily activities, including climbing trees, likely help to keep their nails short and functional for their needs.
Overall, monkeys' fingernails play an important role in their ability to climb trees and perform other necessary tasks, showcasing the versatility and functionality of these evolutionary adaptations.

They use their nails to pick off insects during grooming
Monkeys, like all primates, have nails on their fingers and toes. Nails are an evolutionary development that allowed early humans to perform a variety of important tasks that would have been difficult with claws, such as handling food and tools. Nails also enable primates to grip objects and branches more effectively.
Monkeys use their nails for a variety of purposes, including picking up small objects and scratching. Importantly, they also use their nails to pick off insects during grooming. Long nails would impede this process, so monkeys have been observed using a variety of methods to keep their nails trimmed, such as biting them or waiting for them to break off during daily activities like climbing trees or fighting.
While some monkeys may not mind having long nails, they can interfere with the natural movement of their fingers. Captive monkeys have even been known to use human tools like nail files to trim their nails. Ultimately, the way a monkey chooses to groom its nails is a matter of personal preference.
In addition to their functionality, nails also serve a protective role. The hard outer covering of the fingernail strengthens the fingertips, making them one of the strongest parts of the hand. This strength helps to reduce the risk of injury when performing everyday tasks.

Nails protect monkeys from viruses and bacteria
Primates, including monkeys, have fingernails that serve several purposes. One important function of fingernails is protection. The hard, outer covering provided by fingernails makes the fingertips one of the strongest parts of the hand, aiding in everyday tasks such as gripping. This protective layer also acts as a barrier, preventing viruses and bacteria from entering the body.
Fingernails have an intricate network of nerves and a rich blood supply, which is maintained even during tight gripping. This blood flow is enhanced due to the proximity of the fingers to the heart. The nails are composed of three layers of tissue called keratin, a type of tissue with amino acid proteins that is also found in hair.
While long nails can impede the fine motor movements of monkeys, such as during grooming, some monkeys and chimps seem to be unbothered by this adjustment. Monkeys have been observed using various methods to keep their nails trimmed, including biting them or waiting for them to break off naturally. Captive monkeys may also use human tools like nail files. Daily activities, such as climbing trees and fighting, likely help keep their nails short.
The evolution of nails instead of claws in primates is attributed to the dexterity and functionality that nails provide. Nails allow for a more solid grip on branches during climbing, enabling our ancestors to move from tree to tree more efficiently. Additionally, nails are better suited for handling food, picking bugs, and completely closing the hand to grip, whereas claws would inhibit these motions.

Monkeys bite their nails, or wait for them to break off
Monkeys, like all primates, have fingernails that serve several purposes. These include strengthening the fingertips, enhancing fine motor movements, and providing protection from viruses and bacteria. However, long nails can impede a monkey's normal finger movements and ability to pick off insects during grooming.
While some monkeys may use human tools such as nail files, they do not have access to manicures or nail clippers in the wild. So, how do they keep their nails trimmed? Some monkeys bite their nails, while others simply wait for them to grow too long and break off on their own. Biting their nails is a common behaviour among primates, including chimpanzees, and is an inherited way to treat nails, called onychophagia.
There is no one definitive habit that unites non-human primates when it comes to nail grooming, as it ultimately comes down to personal preference. Some monkeys may prefer to bite their nails, while others may find it uncomfortable and choose to wait for their nails to break off naturally. Captive monkeys may have access to human tools like nail files, but wild monkeys must rely on their daily activities, such as climbing trees, harvesting bamboo shoots, and fighting rivals, to help keep their nails short.
The continuous growth of nails in primates suggests a similarity to shark teeth, which constantly replace themselves due to wear. Nails in primates, including monkeys, may also naturally wear off through their daily activities and not require any active trimming behaviour. This is in contrast to human behaviour, where long nails can be a choice that requires adjustments in daily activities, such as typing or texting.

Fingernails are stronger than claws and help with gripping
Fingernails are present in all primates, including monkeys, apes, and humans. They are stronger than claws and provide several advantages, particularly in terms of dexterity and gripping.
The hard, outer covering of fingernails makes the fingertips one of the strongest parts of the hand, enabling monkeys to perform various tasks, including gripping branches and holding onto trees while climbing. This strength is further enhanced by the abundant blood supply to the fingernails, which can be maintained even when a monkey is gripping something very tightly.
Fingernails are flat, wide, and shield-shaped, located at the back of the fingertips. This shape and position allow monkeys to wrap their fingers around tree branches securely. In contrast, claws are thin, curved, and pointed, wrapping around the end of the fingers, which would hinder precise movements and make it challenging to grasp small objects.
The advantages of fingernails over claws are evident in activities such as grooming, where monkeys use their fingernails to pick off insects. Additionally, the intricate network of nerves underneath the nail enhances sensation, further improving their dexterity.
While long nails can impede finger movements and certain tasks, monkeys have various methods to keep their nails trimmed. Some bite their nails, while others wait for them to grow too long and break off during activities like climbing trees, harvesting bamboo shoots, or fighting with rivals.
