Study: Great White Sharks Eat Right and Eat Often

The magnificent Great White Shark was accused of being an “eating machine” in 1975’s Jaws, and apparently Matt Hooper, a marine biologist played by Richard Dreyfuss, was right.


A recent study, replacing one done in the 1980s is that a great white could snack on a 60-pound seal and not eat again for 6- 8 weeks.  Well, now the conventional wisdom is eat right and eat often, according to researchers at the University of Tasmania and reported by AFP.

As it is, these huge sharks are likely to be feeding every few days, not every few weeks. The findings are based on a careful, meticulous study of a dozen sharks that factored in their metabolic rate and swim speeds. So why was the old study so far off? The best guess is that “they picked a shark that probably wasn’t working very hard at the time when they did it,” one of the new researchers tells Australia’s ABC News.

Unfortunately, Great White Sharks are still endangered, and every effort must be made to save them from certain death at the hands of Asian shark finners and bragging trophy fisherman, and vengeful officials following the rare encounters between sharks, surfers, swimmers, and others who trespass in their world.

    Great White Sharks are beautiful creatures that have been vilified since the movie “Jaws”. Most likely before that most people did no have a clue that there was such an animal. A shark was a shark. Most attacks on humans are committed by the Bull Shark and that is only because they tend to stay in shallow waters and even venture into fresh water occasionally. That being said, there is a line from “Jaws” that is totally accurate when said in relation to a beach area. “Martin, when you say Barracuda, nobody pays attention. When you say Shark, everybody gets scared to go near the water.” I guess if you ever found a 2000lb Barracuda it would be different.
