The whopping shark known as Carcharodon megalodon went extinct 2.6 million years ago. So if you travel far enough back in time, there may be some fact to the fiction of Moby Dick. Hyenas, lions, and tigers generate around 1,000 psi (4,450 newtons). Imagine a great cavernous mouth, edged by hundreds of razor-sharp teeth. Such terrifying jaws are familiar from monster movies, from Jaws to Godzilla. Spotted Hyenas kill prey and hunt in packs. They have around 50 conical teeth, which they use to rip apart prey – from seals to grey whale calves. Fortunately, most mastiffs have gentle dispositions; you can blame their large sizes and ferocious jaws on ancient human civilizations, which bred this dog for combat and "entertainment" (such as fighting mountain lions in arenas, the equivalent of Monday night football 2,000 years ago). Strength and bite force. There's a good number of dogs stronger than a Hyena, but the Hyena will win everytime. A leopard, though bulkier and stockier than their counterparts, has a bite force of between 300 to 310 pounds per square inch while that of a cheetah is a significant 475 pounds per square inch. As incomprehensibly huge as this number is, it makes perfect sense since Megalodon's hunting style was first to methodically shear off the fins and limbs of its prey, then deliver a killing blow to the unfortunate animal's underside. Humans in fight or flight mode can continue fighting with a broken bone. I'm 100% sure a spotted Hyena would take care of a pitbull with ease. It only has teeth on its lower jaw and tends to swallow its squid diet whole. They are also known as orcas and can grow to 31ft (9.5m) long. 228 lbs higher than the rottweiler, around 330 lbs higher than the pitbull, and a 152 lbs higher than the wolf. The Rottweilers were the strongest and topped with 328 pounds of bite pressure. 05-25-2011, 07:42 AM #30. grizzlebees. (Interestingly, the dog you'd expect to see on this list, the pit bull, can only muster a bite force of 250 PSI, about the same as a full-grown human.) But it uses them to scrape, not gnash, so it cannot be said to bite. "Don't worry, being eaten by a crocodile is just like going to sleep—in a blender!" This helps explain why the biggest crocodiles have such strong bites. Also, hyenas don't instantly break bones with their bite, it would have to chew for a while. They kill lions in the wild. Join over five million BBC Earth fans by liking us on Facebook, or follow us on Twitter and Instagram. Of course, the possibility exists that other tyrannosaurs, such as Albertosaurus, had equally formidable bites — and no one has yet performed simulations of the two largest meat-eating dinosaurs of the Mesozoic Era, Spinosaurus, and Giganotosaurus. "Considering the jaw, teeth and skull size and proportions, very powerful bites can be reasonably expected for this animal.". Logically enough, spotted hyenas can count among their ancestors the "bone-crushing dogs" of the later Cenozoic Era, such as Borophagus, relentless predators that could crush the skull of an Indricotherium as easily as a prehistoric grape—and evolutionarily speaking, spotted hyenas are not all that far removed from the mastiffs discussed previously. Pit bull has only teeth. There are no living Deinosuchus specimens to hook up to measuring equipment, but extrapolating from the saltwater crocodile — and examining the shape and orientation of this prehistoric crocodile's skull — paleontologists have arrived at a bite force of a whopping 20,000 pounds per square inch. I have heard some pit bulls have naturally secreted pain killer and/or brain circuitry that serves to deaden or preclude pain. However, in a 2012 study, researchers measured the bite force of the black piranha to be 320N. Bob Strauss is a science writer and the author of several books, including "The Big Book of What, How and Why" and "A Field Guide to the Dinosaurs of North America. A handpicked selection of stories from BBC Future, Earth, Culture, Capital, Travel and Autos, delivered to your inbox every Friday. Kangals are guard dogs originating from … It is believed to be the bite of a Nile crocodile is as high as … According to Dr. Brady Barr, on National geographic, the hyena has a bite force that has been recorded at 1000 lbs. German Shepherds came in second with a 238 measured bite force, and the American Pit Bull Terrier came in third with 235 pounds of pressure. 10 pitbulls have nowhere near the bite force of an adult male lion. "Just because an animal could hypothetically generate a particular force doesn't mean that it did. American Pit Bull Terrier The American Pit Bull Terrier (APBT) is a medium-sized, solidly built, short haired dog whose early ancestors came from England and Ireland. As you peruse the following images, bear in mind that the PSI of an adult human male is about 250—an order of magnitude less than most of the animals spotlighted here. Bite Force – 743 PSI. The shark bite researchers estimated the megashark's bite to be an "extraordinary" 108,514-182,201N. There are mastiffs out there that bite with the same force as hyenas do. "Their jaw-closing muscles show positive allometry," says Porro. Some of the bigger breeds mentioned, … Still, by observing animals in the wild, and performing computer simulations, it's possible to arrive at a more-or-less accurate number for a given species' bite force, expressed in pounds per square inch (PSI). Hyenas have much stronger bite force, are probably faster, weigh more (females can reach 141lbs, males normally over 100lbs but less than 120lbs), etc. Lions can weigh in from 300-450kgs per adult male and they do spar with other lions for territory and females. At the other end of the scale, the diminutive South American fish known as piranhas have a reputation for biting sizeable chunks out of their prey. Well, the bite force of the average dog is placed around 230-250 PSI even though some of these dogs have more strength. There is a reason people show up to dog fights with bully breeds and not wolf hybrids. It is not the teeth or long jaws of crocodiles that give them a big bite, but the ferocious snap, according to Laura Porro of the Royal Veterinary College in London, UK. Not only that, unlike modern sperm whales it had functional teeth in both jaws. What can you say about a 50-foot-long, 50-ton prehistoric shark that preyed on equally sized prehistoric whales like Leviathan? The biting force of a pitbull is nothing compared to that of a hyena's. To really deliver a powerful bite, an animal needs a big mouth, lots of strong teeth, and powerful muscles. Remember that scene in Peter Jackson's "King Kong" where our hero casually rips off a giant tree branch and eats it like a piece of beef jerky? They don't have a bite force that's particularly impressive for their size. The largest hyena is the spotted hyena, and they can grow up to 200lbs. Since Megalodon was, for all intents and purposes, a vastly scaled-up great white shark, it makes sense to extrapolate from the bite force of a great white (estimated at about 4,000 pounds per square inch) to arrive at a truly terrifying PSI of 40,000. If you liked this story, sign up for the weekly bbc.com features newsletter called "If You Only Read 6 Things This Week". It was a whopper: its head alone was 9ft 10in (3m) long. The crocs measured by Erickson's team were not the biggest specimens known, so there could be crocodiles out there with even stronger bites. Similarly, the blue whale may be the biggest animal alive, but it does not have the biggest bite. At 4,000 pounds per square inch, the saltwater crocodile of northern Africa has the strongest bite of any living animal, powerful enough to snag a zebra or antelope by the hoof and drag it kicking and bleating into the water. The largest dogs in the world, mastiffs can tip the scales at over 200 pounds—and these canines have bites to match, wielding a force of 500 pounds per square inch. Yes, that’s 1500. But back in the real world, which animal has the worst bite of them all? 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. you would have to be a dumb mother ****er to think that, hyenas bite force is like 2x a pit bulls plus team 2 wins, the eagle will pwn all, brb swooping down at high speeds and grabbing with sharp claws. A hyena's neck is solid muscle with thick skin, they are notoriously brutal with each other. Despite their name, killer whales are actually dolphins. your looking at a top bite force of 775 to 875 lbs. The first thing to understand is that not every animal with teeth can bite. If you're about to be eaten by a big cat, it will probably make little difference to you whether it's a lion, a tiger, a puma, or a jaguar. It is a member of the molosser breed group. Plenty of animals have big mouths filled with sharp teeth, but only one had a bite this powerful. I'm pretty sure that the top hyena in the planet is going to wreck Hulk. To find out, someone had to measure the force it exerts. This may seem like overkill, considering that a rampaging polar bear can render its prey unconscious with a single swipe of its well-muscled paw, but it makes sense given that many animals in Arctic habitats are swathed in thick coats of fur, feathers, and blubber. That's how Homer Simpson tries to reassure Bart and Lisa during their safari to Africa, way back in the wilds of season 12. "If you look at a photograph of a large croc, these are the big fleshy jowls hanging near the back corner of their mouths.". While the lion does not have to solely rely on biting. However, in a 2012 study, researchers measured the bite force … For comparison, our best bite with our second molars is estimated at a maximum of 1,317N. Pit bull has enormous jaw strength. It is not the teeth or long jaws of crocodiles that give them a big bite, but the ferocious snap. Answer by Preston Cook A pit bull that gets scared and backs down is a bad dog. It may have grown to almost 66ft (20m) long, nearly 3.5 times the length of the biggest great white sharks. All big bears (including grizzly bears and brown bears) have roughly comparable bites, but the winner by a nose—or, we should say, by a back molar—is the polar bear, which chomps down on its prey with a force of about 1,200 pounds per square inch, or more than four times the power of your average Inuit. In 2008, Stephen Wroe of the University of New England in Australia and his colleagues used computer simulations to estimate how powerful a great white shark's bite could be. ^ Here are 3:40 a small first attempt bite of a small mastiff bite down with 556 lbs. Around 9 million years ago, South America was home to giant piranhas. What is the bite force of a great white shark? “Average” BFQ was set at 100. Very powerful bites can be reasonably expected for this animal. Erickson's team caught and restrained the animals, then placed the transducer between their back teeth where the bite forces were greatest. That is feeble compared to the great white shark, even when you factor in the size difference. This meant only the "jaw adductor" muscle forces were measured, without any twisting forces. In contrast to a human’s 162 pounds per square inch bite force, these two animals are champion choppers. "The largest living [animal] using its teeth for catching its prey and tearing pieces off it is the killer whale," he says. They kill lions in the wild. Oddly enough for an animal with such a deadly bite, the hippopotamus is a confirmed vegetarian; males use their foot-long canine and incisor teeth to duel with other males during mating season, and (presumably) to intimidate any nearby cats whose extreme hunger threatens to overwhelm their common sense. That said, piranhas are not what they were. But compared to other dogs of similar size and weight, it’s lower on the scale. Well, scale that down by an order of magnitude, and you have the modern African gorilla, massive enough to fight off three or four NFL defensive linemen, and equipped with a sufficiently strong bite to mash the toughest fruits, nuts, and tubers to gooey paste. Instead it has plates of baleen, a net-like structure with which it filters food from enormous gulps of sea water. The jaguar`s bite force was never measured. A Pittbull has 250 pounds of bite pressure per square inch and a wild Wolf has 1500. The most powerful bite recorded from a living animal belongs to the saltwater crocodile, according to a 2012 study by Gregory Erickson of Florida State University in Tallahassee and colleagues. There could be crocodiles out there with even stronger bites, "We think their high bite force is largely due to enormous jaw-closing muscles, particularly a muscle called the pterygoideus," says Porro. View image of A sperm whale (Physeter macrocephalus) (Credit: Brandon Cole/naturepl.com), View image of An orca (Orcinus orca) or killer whale (Credit: Roland Seitre/naturepl.com), View image of A great white shark (Carcharodon carcharias) (Credit: David Fleetham/naturepl.com), the maximum bite force prediction was 18,216 Newtons, our best bite with our second molars is estimated at a maximum of 1,317N, View image of Saltwater crocodiles (Crocoylus porosus): bitey (Credit: Dave Watts/naturepl.com), View image of A spotted hyena (Crocuta crocuta) (Credit: Constantinos Petrinos/naturepl.com), View image of A black piranha (Serrasalmus rhombeus) (Credit: Willem Kolvoort/naturepl.com), View image of Illustration of a Megalodon (Credit: Ian Coleman (Wildlife Art Company)/naturepl.com), View image of The jaws of a Livyatan melvillei (Credit: Endless Travel/Alamy), sign up for the weekly bbc.com features newsletter. So far, nobody has applied the finite element analysis technique used to model C. megalodon's bite force to L. melvillei.As a result, we cannot compare their estimated bite forces. Previous techniques for simulating bite force had considered the jaw as a two-dimensional lever, but Wroe used a method that went much further. For now, that is the strongest bite that has been formally estimated. Spotted Hyenas kill prey and hunt in packs. Saltwater Crocodile (4,000 PSI) "Don't worry, being eaten by a crocodile is just like going to sleep—in … Read about our approach to external linking. At the same time that C. megalodon prowled the seas, there was also a sperm whale called Livyatan melvillei. The Greenland Dog (also known as Greenland Husky) is a large breed of a husky-type dog kept as a … A jaguar has such robust jaw muscles that it can drag the carcass of a 200-pound tapir through and out of the water, as well as high up into the branches of trees, where it digs in at leisure for its afternoon meal. Oddities like these mean it is no simple task to find the biggest bite on Earth. I'm pretty sure a bite from a hyena could crush a pit's skull. People need to realize that pitbulls aren't as dangerous as idiots think they are. "With such skull and teeth sizes, Livyatan melvillei is undoubtedly one of the biggest bites of all time, if not the biggest," says Olivier Lambert, who was part of the team that first described the giant sperm whale. An I don't if it's just kids comments I read about Spotted hyenas that completely over-rate them. I'm 100% sure a spotted Hyena would take care of a pitbull with ease. While it's difficult to nail down their exact PSI — estimates range from 500 to 1,500 — there's no doubt that gorillas have the most powerful bites in the primate kingdom, humans included. The shark bite researchers estimated the megashark's bite to be an "extraordinary" 108,514-182,201N . There is a simple reason: it has no teeth. Bite force quotient (BFQ) is the regression of the quotient of an animal’s bite force in newtons divided by its body mass in kilograms. A few hardy researchers have conducted tests on real live animals. Still, nothing beats measuring the bite of an animal in the flesh. ", ThoughtCo uses cookies to provide you with a great user experience. "As the animal grows, these muscles grow relatively faster than expected. The pit bull actually registered the least amount pressure among the group, despite rumors that bully breeds can clamp down with an alarming 1600 pounds of force. The shark bite researchers estimated the megashark's bite to be an "extraordinary" 108,514-182,201N. These dogs bite with force that exceeds 600 lbs per square inch. If you got a full grown bull mastiff/large mastiff breeds, bite down with all it's might and force. This "bite force transducer" measured how much pressure was applied across a pair of plates by the upper and lower jaw. For instance, the common garden snail has thousands of teeth on its tongue-like radula. If you do some research you would find that even a just teething baby hyena has more than twice the bite force of a pitbull so... no chance in hell a pitbull would win. If a pit bull with that sort of high pain threshold got a cheetah by the throat I think it could kill the cat. That is enough to crush a small car. Natural History Museum of Utah/Wikimedia Commons. And while a 2008 computer model estimated that a 21-foot (6.5-meter) great white shark would produce nearly 4,000 psi (17,790 newtons) of bite force, that figure hasn’t been directly measured. Those teeth may be the largest of any animal: they were 14in (36cm) each. I don't know if this is true. According to Olivier Lambert of the Royal Belgian Institute of Natural Sciences, the best contender is not a whale – but it does prey on whales. The crocodile's bite was slightly weaker than that of the great white shark – but the shark's bite was only simulated. And, i have no direct evidence of hyenas crushing elephant thigh bones, other than second hand sources, but i`ve seen hyenas feeding on elephants, and they do eat the bones of their victims. The study also included a simulated bite sleeve test with a German shepherd, a Rottweiler and an American pit bull terrier.
