How long can a shark go without eating?
It means if a great white feeds on a large mammal, it can go for days without eating anything because of high-energy diet. Therefore, a shark measuring about 15 feet can go for about 45 days without eating anything if it devours 66 pounds of fat from a whale (research conducted in 1980s).
