Although hyenas do have very powerful jaws that can even crush bones, there are
other African animals with a more powerful bite.
Biting force is usually measured in pounds per square inch (PSI). A human bite is about 160 psi, whilst a hyena’s bite has been measured at around 1100 psi. Although that is powerful, it is beaten in Africa by the gorilla at 1300 psi, and the hippo with 1825 psi. However, first prize goes to the Nile Crocodile, with a bite that can be as strong as 5,000 psi.
