Bethany Hamilton is a professional surfer, but what makes her more unique than any other surfer? She surfs with only one arm. This is because when she was 13 she was attacked by a shark while surfing. The shark bit off her arm and she nearly lost her life, but miraculously she returned to surfing less than a month later. The movie Soul Surfer, released in 2011, is about Bethanys life. This video has Bethany Hamiltons story.
