Wild animals deliver many awe-inspiring bodily traits to their battle for survival, together with the power to make use of their tooth and jaws for self-defense and feeding. Not surprisingly, nature’s strongest jaws typically belong to apex predators who sit comfortably atop the meals chain, and gathering laborious information on the drive of their bites could be a decidedly dangerous proposition. Researchers have used quite a lot of strategies, from direct measurement to laptop software program modeling, to estimate the forces at work in nature’s chunk membership. Expressed as PSI (pound-force per sq. inch, a stress of one-pound of drive utilized to a floor space of 1 sq. inch), right here’s how a few of the strongest jaws within the wild stack up.

1. Nice White Shark

Chew Power: 4,000 PSI

In 2008, a workforce of Australian scientists led by Steve Wroe used subtle laptop modeling primarily based on a number of x-ray pictures of shark skulls to estimate {that a} 21-foot nice white shark can produce practically 4,000 PSI of chunk drive. As a result of chunk power in sharks is extremely depending on dimension; the rather more widespread 11- to 15-foot nice whites would pack significantly much less punch than a equally sized croc. And Wroe’s projections, in contrast to Erickson’s findings, haven’t been instantly measured in subject assessments. Volunteers, anybody?

2. Saltwater Crocodile

Chew Power: 3,700 PSI

Dr. Gregory Erickson, professor of anatomy and paleobiology at Florida State College and curator of the college’s Organic Science Museum, performed a 10-year examine to scientifically measure jaw power in all 23 crocodile species. Erickson and his workforce positioned a specifically designed chunk drive transducer—which he likens to “an costly toilet scale” wrapped in “protecting layers of bullhide”—between the jaws of a number of crocodile specimens. The best studying, 3,700 PSI, was registered by a 17-foot saltwater croc. “It’s the very best chunk drive ever recorded,” Erickson says, “beating a 2,980-PSI worth for a 13-foot wild American alligator.”

Notably, the workforce’s information permits projections of bite-force power in now-extinct crocodiles discovered within the fossil file, together with 40-footers estimated to have been able to producing 23,000 kilos of drive. That surpasses estimates for Tyrannosaurus rex, which Erickson estimated, in a 2017 examine, most likely had a chunk drive round 8,000 PSI.

“If you happen to can bench press a pickup truck, you possibly can escape a croc’s jaws,” Erickson says. In any other case, “It’s a one-way avenue between the tooth and the abdomen of a big croc.”

Chew Power: 1,800 PSI

With tusks that may develop two toes lengthy, a mouth that opens 180 levels, and a chunk that may crush an entire watermelon like a grape, hippos probably have the strongest jaws of any herbivore on the planet. Territorial and probably aggressive, hippos are notably hostile to crocodiles and are stated to be able to biting a 10-foot croc in half. The chunk drive of females have been measured at 1,800 PSI; males have reportedly confirmed too aggressive to check.

4. Jaguar

Chew Power: 1,500 PSI

The most important cat within the Americas can also be the strongest biter of any wild feline. Not like all different cats, which principally go for the throat to dispatch their prey, the jaguar kills by biting its sufferer’s cranium and is able to puncturing a turtle’s shell with its tooth.

5. Gorilla

Chew Power: 1,300 PSI

It not a lot the tooth, however the large neck and jaw muscle tissues that give the gorilla one of the vital highly effective bites within the primate kingdom. They’re herbivores, sure, however their weight-reduction plan consists of a lot harder stuff than bananas: The gorilla’s sturdy molars permit them chew heavy shoots, bark, nuts, tubers and different fibrous meals. Lengthy, sharp canines seen in mature males are principally for show.

6. Polar Bear

Chew Power: 1,200 PSI

Not like most bears, whose tooth are designed to deal with each wildlife, polar bears are completely meat eaters—hypercarnivore is the time period. Because of this, their chunk is effectively tailored to coping with the type of prey they encounter within the Arctic: thick-skinned, heavily-feathered or, sometimes, North Face-clad. Polar bears are stated to be the one mammal that actively hunts people.

Chew Power: 1,100 PSI

Hyenas are expert hunters that usually make their very own kills, however their great jaw power additionally permits these African mammals to profitably scavenge carcasses different predators go away behind. Twin-purpose tooth permit them to shear flesh and crush bone, and enormous jaw muscle tissues mixed with a novel arched construction that protects the cranium towards the forces generated by their very own chunk makes hyenas notably environment friendly scavengers: When a hyena pack descends on a kill, there are hardly ever any leftovers.

8. Bengal Tiger

Chew Power: 1,050 PSI

Boasting the longest canine tooth (2.5 to three inches) of all cats, Bengal tigers current a fearsome show; additionally they have the drive to again it up, delivering greater than a thousand pounds-per-square inch of stress—virtually twice as a lot chunk drive because the king of the jungle.

9. Grizzly Bear

Chew Power: 975 PSI

Mythologized for his or her purported potential to decapitate a moose with a single swipe of their large paws, grizzlies even have one of many extra fearsome set of choppers within the wild. Docs in bear nation have developed antibiotic cocktails to combat the deep-tissue bacterial infections that survivors of grizzly bites typically face. Their chunk drive is claimed to be sturdy sufficient to crush a bowling ball.

10. Lion

Chew Power: 650 PSI

Lions have a chunk drive of solely 650 PSI, which isn’t a lot stronger than the hardest-biting home canine, the English mastiff (550 PSI). However lions are social creatures that hunt in teams and devour their kill the place it falls, which can reduce the necessity for particular person jaw power, some researchers have hypothesized. By comparability, people exert a chunk drive of round 160 PSI once we clamp down—ok to energy by way of a troublesome steak sandwich, however nowhere close to satisfactory for bringing a wildebeest to bay.

Correction (December 2, 2021): The rankings of the good white shark and saltwater crocodile have been corrected to no. 1 and no. 2, respectively. They had been beforehand swapped.
