Most powerful bite
Last updated: October 12, 2017 at 19:47 pm
In 2012, researchers at the University of South Florida estimated that the bull shark (Carcharhinus leucas) has a biting force of 3 metric tons (6,000 lbs). The white shark (Carcharodon carcharias) has a biting force of 1.8 metric tons (two tons), more than three times that of the bite of an African lion and more than 20 times that of a human. In 2008, researchers at the University of New South Wales in Sydney estimated that the extinct megalodon shark (Carcharocles megalodon) had a biting force up to five times that of the bull shark. That would make it even more powerful that the Tyrannosaurus rex, a dinosaur which had a maximum biting force of 3.1 metric tons (3.42 tons).
