Thousands of black tip and spinner sharks are swarming off the beaches in Florida, making the usual bustling shoreline looking more like isolated beaches except for a few shark watchers. According to NBC News on Thursday March 7, 2013, several beaches were closed due to the swarms of sharks just a few hundred feet off shore.
Live Science reports as many as 15,000 sharks are swarming off the Florida beaches. Biologists report that the sharks have been migrating from Boca Raton to Jupiter since the beginning of March. The sea creatures spent the winter months in the south and with spring coming they start to migrate north.
Swimmers are advised to swim at the beaches where there are lifeguards and to stay close to shore. They also suggest taking off any jewelry because the silver, yellow and gold attract the sharks.
Lifeguards at Palm Beach said they spotted at least 50 to 60 sharks on Tuesday. A Riviera Beach lifeguard said the sharks like to jump out of the water and come in as close as 30 feet to the shoreline, according to Fox News on Thursday.
The pictures and videos of these swarms of sharks coming out of Florida today look surreal. The water is littered with the black shadows of the sharks, with just a foot or so between many of the sharks. This is how dense the swarm is.
