Shark bites

I have done a huge amount of research on shark bites to understand who is the most feared. It is to be believed that the great white should and usually is the most feared shark due to its size. A great white is 24 feet long that's pretty big and scary. It has a bite force of 9,300 Newtons in their front teeth and in their back teeth it is 18,200 Newtons of snapping power. It has been shown that a bull shark has the strongest bite. They are an infamous man eater, have a stronger bite than a hammer shark, great white, and tiger shark. May have a strong bite due to the appetite for turtles to crunch through the shell. Bull sharks have a very high tolerance for fresh water an have been known to swim very far upstream. Bull sharks bite is 6,000 Newtons in the back and 2,000 in the front of their jaw. They are usually about 8 feet long. The difference is that great white have a huge amount of snapping power but  not a very strong bite. The most ferocious sharks are the great white, hammer head, bull shark, black tip shark, and horn shark. It is believed that the attacks that inspired the movie jaws was actually by bull sharks.
