The bite force of females has been measured at 1,800 PSI males have reportedly proven too aggressive to test. Territorial and potentially aggressive, hippos are particularly hostile to crocodiles and are said to be capable of biting a 10-foot croc in half. With tusks that can grow 2 feet long, a mouth that opens 180 degrees, and a bite that can crush a whole watermelon like a grape, hippos likely have the strongest jaws of any herbivore on the planet.

Hippopotamus Hippos are capable of biting crocodiles in half. Also, Wroe’s projections, unlike Erickson’s findings, have not been directly measured in field tests Volunteers, anyone? 3. Because shark bite force is highly dependent on size the much more common 11- to 15-foot great whites would pack considerably less punch than a similarly sized croc, which therefore belongs in the No. But first, in 2008, a team of Australian scientists led by Steve Wroe used sophisticated computer modeling based on multiple x-ray images of shark skulls to estimate that a 21-foot great white shark can produce nearly 4,000 PSI of bite force. Why is this one in second place if the PSI is higher? We’ll get to that in a sec.

Otherwise, “It is a one-way street between the teeth and the stomach of a large croc.” 2. “If you can bench press a pickup truck, you can escape a croc’s jaws,” Erickson says. That surpasses estimates for Tyrannosaurus rex, which Erickson estimated, in a 2017 study, probably had a bite force around 8,000 PSI. Notably, the team’s data allows projections of bite-force strength in now-extinct crocodiles found in the fossil record, including 40-footers estimated to have been capable of generating 23,000 pounds of force. “It’s the strongest bite force ever recorded,” Erickson says, “beating a 2,980-PSI value for a 13-foot wild American alligator.” The highest reading, 3,700 PSI, was registered by a 17-foot saltwater croc. Erickson and his team placed a specially designed bite-force transducer-which he likens to “an expensive bathroom scale” wrapped in “protective layers of bullhide”-between the jaws of multiple crocodile specimens. Gregory Erickson, professor of anatomy and paleobiology at Florida State University and curator of the school’s Biological Science Museum, conducted a 10-year study to scientifically measure jaw strength in all 23 crocodile species. What animal has the strongest bite force ever recorded? The saltwater crocodile. Cultura Creative/Alamy Crocodile Bite Force: 3,700 PSI Saltwater Crocodile Saltwater crocs have the highest bite force ever recorded. Expressed as PSI (pound-force per square inch, a pressure of one-pound of force applied to a surface area of one square inch), here’s how some of the strongest animal bites in the wild stack up.

Researchers have used a number of methods, from direct measurement to computer software modeling, to estimate the forces at work in nature’s bite club.

But collecting hard data on their bite force can be a decidedly risky proposition. Not surprisingly, when it comes to what animal has the strongest bite force, nature’s strongest jaws often belong to apex predators who sit comfortably atop the food chain. Among the most impressive physical attributes wild animals bring to bear in their battle for survival is the ability to simply chomp down hard.
