Kathy Perry dropped us a line to strongly suggest that what the picture is depicting is not top fin of a shark but something unrelated. Here’s her correction…
Locals may know this photo is only the side of a gray whale’s tail – a behavior called “sharking” as the whale eats on his side at the bottom of the water column in shallow water with the tip of his tail (fluke) sticking out. Some of our tourists may believe this is truly a shark. I, as an interpretive volunteer, as well as local marine officials are frequently contacted by panicked tourists that a shark is near the shore.
I might suggest a footnote identifying the photo as a gray whale “sharking” so the uninformed aren’t afraid of our Oregon waters.
