If you live in South Florida, do NOT go into the water!!
Literally tens of thousands of sharks were seen off the coast, right in the shallow water.
A lifeguard supervisor for a South Florida beach said:
"We got here this morning and they were thick, really thick. They were frenzied and chasing bait all the way up to shore. They were practically right on the sand."
A biology professor who was tracking the migration of the sharks said that he counted over 15,000 sharks less than 200 yards from shore!!
The risk of attack is apparently pretty low because the water is so clear, a shark can more easily distinguish humans from prey.
But they're still scary, and dozens of beaches in South Florida are still closed.
We recommend everyone just stay OUT of the water!!
Check out the video (above) to see dozens of sharks swimming just off the coast.
