Bull sharks have strongest bite of all shark species


Bull sharks have the strongest bite of any shark species, scientists have discovered.
Relative to their body size, bull sharks bite harder than other, larger predatory sharks.
Adult bull sharks can bite with a maximum force equivalent to 6,000N, a study of their jaws and jaw muscles has shown.
It is unclear why bull sharks have such strong bites, which are much greater than required to kill and eat prey.
Details of the discovery are published in the journal Zoology.
Maria Habegger of the University of South Florida in Tampa, US and colleagues in the US and Germany examined bite forces produced by 13 species of shark and their close relatives.
