COCOA BEACH, Fla. (FOX 35 ORLANDO) - Lifeguards at Shepard Park in Cocoa Beach spotted the fin of a blacktip shark on Wednesday.
The shark was spotted from one of their watch towers and was about 100 yards from the shoreline. That prompted a closure of the beach for swimmers, for approximately 30 minutes.
"It's very scary. I think I'm not putting my feet in the water anymore," explained Luna Cohen, who was hosting friends on vacation from Brazil.
She said she had a close encounter with a shark in Titusville a couple of years ago, and she still a little spooked about it.
"I was in the shallow area too, it was by my knees, but the lucky thing was I was able to run out!"
Officials said a blacktip shark is about two to five feet in length and it the type of shark that commonly bites humans -- they swim in very shallow water, sometimes in just a few inches of water.
With a big holiday weekend, swimmers are being asked to stay alert.
