A giant hammerhead shark swims in the shallows off Destin, Florida, chasing after its next meal while two oblivious swimmers bask in the crystal clear water just feet away. 'Get out the water!' cries a man with a group of friends on a penthouse balcony overlooking the beach, and for a long time to no avail, until they finally spot the danger as the shark's chase leads it too close to them for comfort. While the likelihood that serious injury would have been very unlikely should the shark have turned its attentions to them, the swimmers weren't willing to stick around to confirm it. Two swimmers stand oblivious to a hammerhead shark as it hunts a fish in the shallows off Florida . The swimmers were shouted at to get out of the water by a group of men standing on a penthouse balcony . Hammerheads are largely harmless to humans, but the swimmers were willing to stick around to prove it . 'Yeah, now run,' said one of the group of men watching and filming the shark as it displayed the full range of its agility in pursuit of the fish, perhaps a small stingray, one of the species' favourite foods. 'I think they finally figured it out,' said another of the residents at the Silver Beach Towers. 'That is a massive shark, and it came all the way up to knee level.' Destin is a resort town in Okaloosa County, Florida, on the peninsula that separates the Gulf of Mexico from Choctawhatchee Bay. While their hearts may have been racing once they were safely on the beach, the Florida Museum of Natural History's International Shark Attack File lists 17 unprovoked attacks on humans by hammerheads, with none of them fatal. 'Yeah, now run,' said one of the group of men watching as the hammerhead ramped up its chase of the fish . The swimmers are surely relieved once on shore, although serious injury was highly unlikely . Only three of the 11 known species of hammerhead are believed to be hostile to humans, the scalloped, great, and smooth hammerheads. It's a different story with great white, tiger or bull sharks, which are considered the "Big Three" when it comes to shark attacks claiming the majority of fatalities for swimmers and surfers.
