So, who has the most powerful jaws? Of all animals alive on Earth today, the
MODERN HUMANS CAN BITE off more than apes can chew, according to new research. Australian scientists have found that the relatively light human skull has a far more efficient bite compared to the jaws of chimpanzees, gorillas, and orangutans.
Tasmanian Devil (200 psi)
Tasmanian devils are thought to have the strongest bite force of any animal when you factor in the animal's size. They weigh in at only 20 pounds (9.07 kg) but can exert 553 Newtons when they bite. They have the highest Bite Force Quotient (BFQ) of any living animal.
Our second molars can exert a bite force between 1,100 and 1,300 Newtons, beating the orang-utan, gibbon and Australopithecus but lagging behind the gorilla, chimp and Paranthropus.
rex—about 35,000 newtons— or to the puny biting power of humans: 300 newtons. Previous bite force estimates for juvenile T. rexes—based on reconstruction of the jaw muscles or from mathematically scaling down the bite force of adult T. rexes—were considerably less, about 4,000 newtons.
Complications from a human bite can be very serious, including severe infection and permanently damaged bones, joints and/or tendons.
Mammal with the Weakest Bite Force: Anteaters
The bite force is a measure of the pressure exerted by the teeth when an animal bites or chews, usually expressed in pounds per square inch (PSI).
At #1 we have Nile Crocodiles with a whopping 5,000 PSI bite. A person's bite strength clocks in on average at just 162 PSI which means the supreme force of Nile Crocodiles is 30 times stronger than ours! Talk about a powerful bite.
The Kangal is a large, muscular dog that typically weighs between 100 and 130 pounds. They have been trained to guard sheep and other flocks against giant predators such as wolves, jackals, and bears. The Kangal has a mighty bite, with a bite force of 743 PSI. It is the highest bite force of any dog breed.
No, an unarmed human could not beat a lion in a fight.
Even if a human came upon a sleeping lion, their chances of killing it would be laughably small. Humans aren't going to knock out a lion with a kick or punch in one shot. They're also not going to strangle a lion to death.
Strength changes
Compared to our closest living relatives, chimpanzees and bonobos, Homo sapiens' skeletal muscle is on average about 1.35 to 1.5 times weaker when normalized for size.
A chimp would win a fight against a human. Although chimps and humans are carnivores with formidable fighting abilities, a chimp is far more aggressive and violent than a person. The ideal plan is to run as fast and as far as possible. Remember that a man is at a disadvantage.
Tasmanian devils consume the entire animal when they eat. Their jaws open up to 80 degrees, generating large amounts of power to tear apart meat and crush bones. They have the strongest bite per body mass of any living mammalian carnivore, exerting a force of 553 N.
A dung beetle is not only the world's strongest insect but also the strongest animal on the planet compared to body weight. They can pull 1,141 times their own body weight. This is the equivalent of an average person pulling six double-decker buses full of people.
Mantis shrimp pack the strongest punch of any creature in the animal kingdom. Their club-like appendages accelerate faster than a bullet out of a gun and just one strike can knock the arm off a crab or break through a snail shell. These small but mighty crustaceans have been known to take on octopus and win.
Jaguar (1,350 psi)
4, beating out lions and tigers when it comes to biting power? It's no mistake. Jaguars have a more powerful bite than any other cat on the planet, and the second most powerful bite of all mammals.
Numerous animal species have the potential to bite humans; however the most important are those arising from snakes, dogs, cats and monkeys.
Labrador Retrievers, Cavalier King Charles Spaniels and Newfoundlands are among the safest dog breeds that are least likely to bite, new research has found. While any dog can nip, these breeds are known for their particularly sweet-tempered spirit as long as they are treated right.
CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community. They can work out how to use things as tools to get things done faster, and they have outsmarted people many a time.
While some animals, like alligators and lions, can chomp down with over 1,000 pounds of force, the average human bite force is only around 200–300 pounds of force.
In reality: Yes, you probably can devour a finger, but it's not comparable to chomping on a vegetable, and gnawing on your own digit would require a substantial commitment to searing pain. Let's hear from an expert.
A human bite can break, puncture, or tear the skin. Bites that break the skin can be very serious because of the risk for infection.
Pain, bleeding, numbness and tingling may occur with any human bite. Symptoms from bites may be mild to severe, including: Breaks or major cuts in the skin, with or without bleeding.
