Monkeys and apes have been observed using a variety of methods to keep their nails trimmed, though there isn't one definitive habit that unites the nonhuman primates.
According to an anthropology professor at the University of Wisconsin-Madison, fingernails are present in all primates, including humans, monkeys, and apes, to support our fingertips. When taking proportions into account, our fingertips are wider on average than those of most other primates.
Many primates bite their nails. Some do not. It's not species specific. Chimpanzees, for example, usually bite their nails; some prefer to leave them alone.
Both gorillas and humans have opposable thumbs and fingers with fingernails. A gorilla's fingernails grow out just like ours; however, they do not need theirs filed, or cut as theirs tend to wear down on through normal gorilla wear and tear.
Long walks can wear down your dog's nails naturally over time. In the wild, wolves and coyotes keep their nails short through digging and running after prey for hours.
Hands and Feet
Gorillas are able to manipulate objects with their feet as well as their hands because of their opposable big toe. Primates have fingernails and toenails rather than claws. They are used for opening, scraping, cleaning, and scratching.
A farrier will trim the hoof and make sure it is healthy. Horse hooves are sort of like your fingernails. You have to trim your nails so they don't get too long. Farriers have to trim a horse's hooves so they don't grow too long and get injured.
Like shy humans, staring directly into the eyes of gorilla make them feel uncomfortable and insecure and when disrupted by your direct eye contact, they can charge aggressively at you to defend themselves.
There have been few cases where gorillas attacked and even killed humans, although such incidents are rare and the human was always to blame. Gorillas can attack if surprised or threatened or if a person behaves in the wrong way in front of them or makes an unexpected movement.
It's a challenge to gorillas
Direct eye contact will therefore force the silverback to charge and fight you in order to defend his family. If you want to be peaceful with gorillas, you should avoid eye contact.
Myth: Chimps can smile like humans do.
Chimps make this expression when they are afraid, unsure, stressed, or wanting to appear submissive to a more dominant troop member.
The reason they do this is to reduce their stress levels and also to strengthen the bonds within the group. Plus, it keeps their fur bug free! If you see our macaques 'chattering' their teeth together, then don't worry, it's not a sign of aggression.
Different forms of self and partner genital stimulation have been observed in the animal kingdom. Oral sex has been observed throughout the animal kingdom, from dolphins to primates. Bonobos have been observed to transition from a simple demonstration of affection to non-penetrative genital stimulation.
While they do kiss with their lips, their smackers are narrower and don't turn out like ours do. Researchers speculate that this anatomical difference could mean that kissing for chimps is not particularly intimate, but rather an expression of connection like the human hug.
The reason primates only have two nipples is that they tend to only give birth to one offspring at a time, though they occasionally will have twins and in rare events, they will have triplets. Animals with four or more nipples usually have multiple offspring with each pregnancy.
In the suborder Strepsirrhini, which includes lemurs, galagos and lorises, the grooming claw is on the second toe. Less commonly known, a grooming claw is also found on the second pedal digit of night monkeys (Aotus), titis (Callicebus), and possibly other New World monkeys.
No, an unarmed human being could not beat a gorilla in a fight. Simply put, gorillas are far too strong for human beings to overcome.
Highly unlikely, if no firearms or tranquilizer guns are involved. A gorilla can reach speeds of 20 mph to 25 mph. In comparison, Usain Bolt's record in the 100-meter dash roughly translates into 23 mph (Bolt reaches peak speeds of around 27 mph—but still).
Social Interactions. Orangutans are generally non-aggressive toward humans and each other. Many individuals reintroduced into the wild after having been in managed care are aggressive towards humans.
Remain calm and lay low.
Remain calm and never attempt to run. A gorilla is faster than most humans and running away will only encourage it to chase after you. Remaining calm and laying low will calm the primate down and stop seeing you as a threat or challenger.
It felt pretty silly to do, but they explained that a human smile is seen as a threatening expression to chimpanzees. When they are afraid or when they are trying to be intimidating, they will show all their top teeth and do what we call a “fear grimace.”
While horses bite humans very rarely, their bites are mostly associated with fatalities. Herein, we report the case of a 23-year old bitten by a domestic horse causing a crush injury to his fourth finger with fracture dislocation of the proximal interphalangeal joint.
Horse hooves are admittedly a lot more durable than human trotters: The hoof wall, which covers the top of the hoof and forms a rim around the bottom, doesn't have any nerves or blood vessels. Horses can safely walk on their own four hooves, wearing down their hoof walls as they go.
Wild horses maintain their own hooves by moving many kilometres a day across a variety of surfaces. This keeps their hooves in good condition as the movement across abrasive surfaces wears ('trims') the hooves on a continual basis.
