June Emerson says she took the photo as her 12-year-old son, Quinn, and his friend were in the water. The picture was taken at 31st Street.
Emerson said she did not notice she had captured the shark, which can be seen in the waves toward the right of the photo, until she reviewed the pictures at home.
It's not known what kind of shark it was, but Emerson says there have been many sightings of young great whites in the area.
