How many pounds of pressure can a shark bite exert?

Sharks have powerful jaws that can exert tremendous biting forces. The exact amount of pressure a shark can bite with depends on the species of shark and the size of the individual shark. However, some shark species can exert bite pressures of several thousand pounds per square inch (psi). For example, the great white shark (Carcharodon carcharias) is known to have a bite force of up to 4,000 psi, while the tiger shark (Galeocerdo cuvier) can bite with a force of up to 3,600 psi. These bite forces are powerful enough to crush the bones of their prey.
