Experts say to avoid swimming when it’s dark or during times of low visibility at dusk and dawn. They also say don’t wear any shiny jewelry when swimming, and don’t swim near people fishing. An attack on any person is rare, but especially after three victims of shark attacks were reported on Florida’s east coast this week, we know it does happen. Thursday, the family of 7-year-old J.J. says doctors believe a shark bit him while he was in the water. “He is doing pretty good,” Grace Sosa said. “It was very scary.” Bryce Albert, 20 is back at his Naples home after he was attacked by a shark while in the water at Juno Beach in Palm Beach County. “It’s healing nicely,” Albert said. “It’s just very yellow, black and blue all over my arm.” And a 9-year-old went to the hospital in Miami Sunday after a shark bit him while he was in the water. “Some of them are migrating some of them are moving into coastal areas,” said John Carlson a NOAA marine biologist. Carlson says were right in the middle of one of the world’s largest shark migrations. “This documentation of very large schools of blacktip sharks and also spinner sharks,” Carlson said. Carlson says attacks on people are very uncommon. Blacktips usually only go for small prey. But from February to April, there could be thousands in the water at one time. “That would make me think twice,” John Davidson said. “You don’t want to be in first thing in the morning and when its dawn,” Denise Sperry said. “At the end of the day, I think they’re a lot more scared of us than we are of them,” Dan Critelly said. Experts say you should take precautions this time of year, but you’re likely safe from sharks. Albert says he hopes he can talk to the boy who just got attacked yesterday to comfort him. He says this experience won’t keep him from going back to the beach. “I’m only 20, I got so much longer to live,” Albert said. “I don’t want to live in fear of the water.”
