Leesa Blais, who posted the video to Facebook, said she and her family were surfing off the Fort Pierce Inlet in St. Lucie County when they spotted a pair of manatees nearby.

"The manatees kept swimming around the boys despite their best efforts to avoid them." Blais' husband used a GoPro camera to film as one of the manatees swam up to one of the boys, Evan, and placed a flipper on his surfboard. "Evan was definitely scared in the beginning -- he thought it was a shark," Blais said. "I think he was a little intimidated by how big the manatee was and how it grabbed his board. Evan thinks he just wanted to surf, too."
