They kill lions in the wild. That means it could be a case of many mouths make light work, and their individual bites might not be especially powerful. The average saltwater crocodile (see #7 on this list) measures about 15 feet long and weighs a little less than a ton. For now, that is the strongest bite that has been formally estimated. If a pit bull with that sort of high pain threshold got a cheetah by the throat I think it could kill the cat. What can you say about a 50-foot-long, 50-ton prehistoric shark that preyed on equally sized prehistoric whales like Leviathan? Powerful muscles work to rip flesh, crush bone and close the maw with terrific speed. That's how Homer Simpson tries to reassure Bart and Lisa during their safari to Africa, way back in the wilds of season 12. 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. The most powerful bite recorded from a living animal belongs to the saltwater crocodile. But it may not be the strongest of all. Nile Crocodile – Bite Force : 5000 psi. 05-25-2011, 07:42 AM #30. grizzlebees. While the lion does not have to solely rely on biting. But it uses them to scrape, not gnash, so it cannot be said to bite. That said, piranhas are not what they were. That is enough to crush a small car. 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. Erickson's team caught and restrained the animals, then placed the transducer between their back teeth where the bite forces were greatest. 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? I'm 100% sure a spotted Hyena would take care of a pitbull with ease. The shark bite researchers estimated the megashark's bite to be an "extraordinary" 108,514-182,201N. Such terrifying jaws are familiar from monster movies, from Jaws to Godzilla. People need to realize that pitbulls aren't as dangerous as idiots think they are. The shark bite researchers estimated the megashark's bite to be an "extraordinary" 108,514-182,201N. For this reason, the giant prehistoric ancestors of our crocs, sharks and whales are estimated to have had the biggest bites of all time. 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. However, in a 2012 study, researchers measured the bite force of the black piranha to be 320N. The average bite strength turned out to be 269 pounds of pressure. Tyrannosaurus Rex has been extinct for 65 million years, but its reputation lives on. Human wins. "The largest living [animal] using its teeth for catching its prey and tearing pieces off it is the killer whale," he says. 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. In contrast to a human’s 162 pounds per square inch bite force, these two animals are champion choppers. Saltwater Crocodile (4,000 PSI) "Don't worry, being eaten by a crocodile is just like going to sleep—in … 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. The American Pit Bull diverges in appearance from the Staffordshire Bull Terrier, having fewer bulldog traits in the face and body. View image of A sperm whale (Physeter macrocephalus) (Credit: Brandon Cole/, View image of An orca (Orcinus orca) or killer whale (Credit: Roland Seitre/, View image of A great white shark (Carcharodon carcharias) (Credit: David Fleetham/, 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/, View image of A spotted hyena (Crocuta crocuta) (Credit: Constantinos Petrinos/, View image of A black piranha (Serrasalmus rhombeus) (Credit: Willem Kolvoort/, View image of Illustration of a Megalodon (Credit: Ian Coleman (Wildlife Art Company)/, View image of The jaws of a Livyatan melvillei (Credit: Endless Travel/Alamy), sign up for the weekly features newsletter. For instance, the common garden snail has thousands of teeth on its tongue-like radula. At the same time that C. megalodon prowled the seas, there was also a sperm whale called Livyatan melvillei. 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. The jaguar`s bite force was never measured. A single paw strike could prove fatal for the pitbull. Those teeth may be the largest of any animal: they were 14in (36cm) each. Humans in fight or flight mode can continue fighting with a broken bone. 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. 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. It may have grown to almost 66ft (20m) long, nearly 3.5 times the length of the biggest great white sharks. I'm 100% sure a spotted Hyena would take care of a pitbull with ease. 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. The largest living [animal] using its teeth for catching its prey and tearing pieces off it is the killer whale. The biting force of a pitbull is nothing compared to that of a hyena's. 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. The largest saltwater crocodiles delivered a crushing 16,414N, more than 3.5 times that of the previous record-holder, the spotted hyena. It was a whopper: its head alone was 9ft 10in (3m) long. 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. However, as any fan of nature documentaries can tell you, orcas usually hunt co-operatively to take down big prey. Hyenas have much stronger bite force, are probably faster, weigh more (females can reach 141lbs, males normally over 100lbs but less than 120lbs), etc. 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. However, "it would definitely [be] worth trying," says Lambert. In 2012, a team of researchers in England simulated the skull and musculature of T. Rex, using modern birds and crocodiles as reference points. That is feeble compared to the great white shark, even when you factor in the size difference. 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 team compared 23 crocodilian species, by persuading the reptiles to bite a metal sandwich on a pole. 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. Named for the author of the ultimate whale tale, this huge whale lived in some of the same places as the mega-shark, and hunted the same prey. ^ Here are 3:40 a small first attempt bite of a small mastiff bite down with 556 lbs. An I don't if it's just kids comments I read about Spotted hyenas that completely over-rate them. It only has teeth on its lower jaw and tends to swallow its squid diet whole. But compared to other dogs of similar size and weight, it’s lower on the scale. There are mastiffs out there that bite with the same force as hyenas do. The sperm whale looks more promising, as it is the largest toothed predator on Earth. There is a reason people show up to dog fights with bully breeds and not wolf hybrids. Not only that, unlike modern sperm whales it had functional teeth in both jaws. The study also included a simulated bite sleeve test with a German shepherd, a Rottweiler and an American pit bull terrier. Oddly enough, though, the muscles the saltwater crocodile uses to open its jaws are very weak; its snout can be wired shut (by an expert, of course) with just a few rolls of duct tape. This "bite force transducer" measured how much pressure was applied across a pair of plates by the upper and lower jaw. The first thing to understand is that not every animal with teeth can bite. Even if the Hyena does manage to break a bone, the man can still get a grip around the Hyenas neck with his free arm and choke it to death. 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. The crocodile's bite was slightly weaker than that of the great white shark – but the shark's bite was only simulated. Still, nothing beats measuring the bite of an animal in the flesh. "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. This helps explain why the biggest crocodiles have such strong bites. The Rottweilers were the strongest and topped with 328 pounds of bite pressure. Read about our approach to external linking. The largest hyena is the spotted hyena, and they can grow up to 200lbs. ", ThoughtCo uses cookies to provide you with a great user experience. As befitting mammals that can eat, chew and digest solid bone, spotted hyenas are equipped with massive skulls, disproportionately large trunks and forelimbs, and powerful bites that can rip through carcasses with up to 1,000 pounds of force per square inch. Also, hyenas don't instantly break bones with their bite, it would have to chew for a while. Join over five million BBC Earth fans by liking us on Facebook, or follow us on Twitter and Instagram. (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.) It is not just a matter of having a big mouth. Natural History Museum of Utah/Wikimedia Commons. Measuring the power of an animal bite can be a notoriously difficult undertaking: after all, very few people (even graduate students) are willing to stick their hands into a hippo's mouth, or attach electrodes to the jawbone of an irritated crocodile. They don't have a bite force that's particularly impressive for their size. FEA allows us to predict stress and strain throughout the skull and jaws, as well as reaction forces, and thus allows us to predict overall mechanical behaviour.". A handpicked selection of stories from BBC Future, Earth, Culture, Capital, Travel and Autos, delivered to your inbox every Friday. "Considering the jaw, teeth and skull size and proportions, very powerful bites can be reasonably expected for this animal.". But according to some sources, you'll emit your dying shriek a little bit louder if you're attacked by a jaguar: this compact, muscular cat can bite with a force of 1,500 pounds per square inch, enough to crush the skull of its unfortunate prey and penetrate all the way to its brain. Yes, that’s 1500. A few hardy researchers have conducted tests on real live animals. So maybe we want a lone predator, in which case we should take a look at the world's biggest predatory fish, the great white shark. Kangal - Dog with the Strongest Bite. Lions can weigh in from 300-450kgs per adult male and they do spar with other lions for territory and females. Despite their name, killer whales are actually dolphins. 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. 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. For comparison, our best bite with our second molars is estimated at a maximum of 1,317N. Bite Force – 743 PSI. "As the animal grows, these muscles grow relatively faster than expected. According to Dr. Brady Barr, on National geographic, the hyena has a bite force that has been recorded at 1000 lbs. They have around 50 conical teeth, which they use to rip apart prey – from seals to grey whale calves. It is not the teeth or long jaws of crocodiles that give them a big bite, but the ferocious snap. There's a good number of dogs stronger than a Hyena, but the Hyena will win everytime. But it is another red herring. Very powerful bites can be reasonably expected for this animal. The whopping shark known as Carcharodon megalodon went extinct 2.6 million years ago. Famous for their 300 blade-like teeth, which are continually replaced, these sharks certainly have one of the most feared bites on Earth.
