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.
