This photo went viral in 2015 claiming to be a sea monster in Greece but, in reality, it might be far from a mysterious sea serpent. The image was taken by 52 year old Harvey Robertson while he was visiting the country on vacation with his family. He leaned over the side of the boat to snap some photos of the water while in a sea cave and when he looked over the pictures he took, he saw this. However, after about a week of this picture spreading around, the real ‘creature’ was found.
Dr. Darren Naish of the National Oceanography Center at the University of Southampton thinks that what Robertson captured on camera was most likely what is called a low freeboard fender. It is an object that helps protect boats from taking damage on dock walls and other obstructions.
