And the strongest known bite force of the entire animal kingdom is…. The Crocodile -- specifically, the Saltwater Crocodile (the highest recorded “live” bite of 3700 PSI) and the Nile Crocodile (estimated 4000-5000 PSI)!
Computers don't lie: T. Rex was shown to have a bite force of over 10,000 pounds per square inch, enough to bite through the head and frill of an adult Triceratops or even (just possibly) penetrate the armor of a full-grown Ankylosaurus.
The anteater, on the other hand, is one mammal with virtually no bite force. In fact, it can barely move its jaws at all! Anteaters collect ants and other foods by extending a long tongue and drawing it back into their mouths.
Chimpanzee (PSI: 1300)
A chimpanzee's biting force is estimated to be roughly 1,300 pounds per square inch (psi). This is around six times stronger than the average human's biting force.
Spotted Hyenas have a fearsome bite force of 1100 PSI. Polar Bears have the strongest bite force of all bears, with a bite force of 1200 PSI. The Grizzly Bear comes in close second with a bite force of about 1160 PSI. Gorillas are mainly plant-eaters - the only non-carnivore on this list!
The Nile crocodile and American Alligator also have very powerful bites, 3,000 PSI and 2,980 PSI respectively. The Nile crocodile is considered the deadliest crocodile species in the world due to its territorial and aggressive nature.
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.
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.
In brute strength, elephants are the strongest mammals and the strongest land animals. African elephants can weigh up to 6,350kg and they can carry up to 9,000kg, the weight of 130 adult humans.
The results show that the elephant wears the crown in the animal kingdom – but only slightly. Elephants had a win rate of 74%, just fractions of a percent ahead of their single-horned cousins – the rhinoceros – in second place, also on 74%. Not far behind in third place is the grizzly bear, at 73%.
The "winners"—saltwater crocodiles—slammed their jaws shut with 3,700 pounds per square inch (psi), or 16,460 newtons, of bite force. By contrast, you might tear into a steak with 150 to 200 psi (890 newtons). Hyenas, lions, and tigers generate around 1,000 psi (4,450 newtons).
Megalodon jaws
Humans have been measured with a bite force of around 1,317 Newtons (N), while great white sharks have been predicted to be able to bite down with a force of 18,216N. Researchers have estimated that megalodon had a bite of between 108,514 and 182,201N.
Rats and house cats were the easiest presumed pushovers, with two-thirds of participants claiming they could see one off, while grizzly bears, elephants and lions were rightfully respected – only 2 per cent of pollsters claimed they would be able to take one down.
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.
In fact, kangaroos are stronger than humans in every aspect except their arms. In the 9 News video below you will see how one man (a boxer) learned this the hard way, when he got into an intense fight with an eastern grey kangaroo in Ballina, New South Wales.
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.
A. The force of the human bite in chewing is usually given as around 70 pounds per square inch, but that figure is for the back molars; the force tapers off toward the front of the jaw, because of the shape of the lever being worked by the jaw muscles.
Numerous animal species have the potential to bite humans; however the most important are those arising from snakes, dogs, cats and monkeys.
Godzilla can bite down with a 500k bite force which tears through the bones and flesh of many kaijus it faces. Godzilla has bioluminescence that it uses to, among other things, intimidate or warn foes. Godzilla's roar can push smaller foes away and even off their feet.
Past megalodon research suggests these giant marine predators, which first appeared around 16 million years ago, could chomp with more than three times the force of T. rex, based on the new figures.
A T-rex would win a fight against a lion, grizzly bear, and saltwater crocodile. The T-rex could eat them and still be hungry later on in the same day.
Nile crocodile (5,000psi)
Even though Nile crocodiles are smaller than saltwater crocodiles, they come in at the top of the charts for the most powerful bite.
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. These forces are roughly what you'd expect for a primate of our size.
That's right – Tasmanian devils deliver the strongest bite for its size of any mammal in the world. Their oversized heads allow them to open their jaws up to 80 degrees wide and their jaws carry enough brute force to crush bone.
