At one point the shark lifted him out of the water to knee level. When the shark dove for deeper water Niblack found himself completely back in the water and scared to death. "And that was the scariest part," Niblack told KATU News. "When I didn't know where it was anymore." Rather than wait for the shark to return, Niblack paddled to shore with what I imagine was supersonic speed. Biologists say that, although rare, great whites do frequent the waters off Oregon.
