However, by using multiple x-ray images to create computer models of the skull of a great white, scientists have estimated the bite force to be about 4,000 psi, which would put the great white in second place. Wait! What about great white sharks? Don't they have pretty strong jaws? They do, but no one has been able to measure the force with a live specimen. Those dudes like to crush their huge prey before swallowing them whole. The first specimen of Paranthropus boisei, also called Nutcracker Man, was reported by Mary and Louis Leakey in 1959 from a site in Olduvai Gorge. Seriously? 3,700 psi?įinally, the champ, the Nile crocodile, at 5,000 psi. Human Bite Force Compares to Chomp of Chimps. A hippo? 1,800 psi (hippos are really good at defending themselves from those apex African predators). The range of human bite forces is very broad and differs due to gender and age. A jaguar? 1,500 psi (definitely a predator). How strong is human jaw The average strength of a human bite is 162 pounds per square inch (PSI), but this pales in comparison to nature’s champion chompers. Human bite force differs throughout the jaw, as teeth closer to the hinge of the jaw are. It’s important to note that pit bulls have a dog’s bite force of 235 PSI, which isn’t the strongest bite force out there. For comparison, normal chewing exerts 70 pounds per square inch. While their bite forces average around 3,000 PSI, some individuals can chomp down at a rate of 5,000 PSI. The maximum bite force for a human male with normal teeth is about 777 Newtons, or 174 pounds for females, it is about 481 Newtons, or 101 pounds. Bite force: 5,000 PSI And the winner of the strongest bite force is the Nile crocodile. A gorilla? 1,300 psi (gorillas aren't predators, but they like to tear bark off of trees with their teeth). By Staff Writer Last Updated April 13, 2020. ![]() Youch! That is definitely bone-crunching power.īut the hyena isn't close to the most powerful. For example, a hyena can bite at 1,100 psi. With the human bite force as our reference point, let's look at the bite forces of some of the animals with the most powerful jaws. To give you some perspective, the average human bite force is only around 120 PSI. This is considered a very powerful bite, ranking the Doberman as the 15th most powerful dog breed. If you've ever had a little brother or sister, you know how much a human bite can hurt, am I right? The Doberman has a powerful bite that can deliver between 245 to 305 PSI of pressure. For perspective, the average bite force for a human is 162 psi. Did you know the Nile crocodile has the strongest bite of all animals? Bite force is typically measured in pounds per square inch (psi). ![]()
