There is no one eating pattern for sharks. In the hundreds of years that many species of sharks have evolved, most have developed a taste for favorite foods. Some only eat once every few weeks. Others aren’t predators at all, and filter plankton out of the water.
For example, Great White Sharks have a great sense of taste. Human beings are not on the menu. Great Whites have what is known as a “bite, spit, and wait” behavior. While there are very few shark attacks on humans, the vast majority of those involve just one bite and a hasty departure.
According to Dr. John McCosker, senior scientist at the California Academy of Sciences, White Sharks can sense after a fraction of a second into its first bite the caloric value of its potential prey. The shark quickly determines whether the “catch” has the right caloric values to warrant the energy to attack it further and eat it. Human beings generally don’t have enough body fat to interest a shark.
