It’s been known for years that great white sharks hang out very close to beaches and swimmers but it may be even more than previously thought.
Researchers have tagged more than 100 great whites on the east coast and the findings might make you think twice about taking a dip.
"What is fascinating is that they approach the shore regularly and have probably been doing this for thousands of years if not hundreds of thousands, but go completely undetected," one marine scientist said.
But the same researcher says there is good news, they rarely bother swimmers.
"I don't think there is any reason to be alarmed. They are not going out of their way to eat us so their reputation is somewhat undeserved. The probability of an attack is so low they obviously have no interest in us."
And it turns out the big fish don’t need GPS to find their way around.
The huge predators can swim as much as 3,000 miles in a few months and can easily return to their favorite spots.
Several of the tagged sharks return to the same exact spot within days every year.
