Probably from the photographer of the famous photograph, who admitted he faked the damn thing...

Look closely at the picture and notice the size of the waves. If that were an actual photo of an actual sea creature, I would have to have been taken in a hurricane for the wave to be that big. He admitted to taking a small model and photographing it in the lake with nothing around to give away any kind of scale. Pretty damn lame hoax if ya ask me...I just can't believe that people have fallen for it for so long...
