15-foot great white female shark spotted with mystery bite mark, pic goes viral

A 15-foot great white female shark was spotted with a mystery bite mark around her side in Isla Guadalupe, Mexico. Photographer Jalil Najafov photographed the scar and said that he was "very lucky" to have spotted the scar before it fully healed. Experts said that the shape indicates a bite from another shark but doesn't look like a mating scar.
