Like a dramatic scene from a Hollywood thriller, a humpback whale suddenly emerged from the water just feet from boats, docks, and onlookers in southeastern Alaska, its giant mouth gaping.

Fisherman Cy Williams recorded the scene at Knudson Cove Marina in Ketchikan, Alaska, on May 2. He tried to follow the path of the big animal under his boat, noting the bubbles rising to the surface.  

“It was breathtaking," Williams told video licensing service Caters TV. "I genuinely thought it was going to hit the boat or the dock as it was so big."

The whale can be seen so clearly that barnacles are visible on its massive chin.

"It's surprising to see the animal so close to the docks," says Leigh
