About a week ago, Oregon surfer Tony Perez was with friends at the mouth of the Siletz River. He happened to have his feet up on the board when out-of-nowhere his board was rammed from below. The blow sent Perez into the water, his feet hitting the shark's body and head above the surface. He swam safely to shore although his board bore the scars: 2-inch teeth marks.

Sunday, a 15-year-old body boarder in Western Australia didn't fare so well. A 15-foot shark took Zac Golebiowksi's right leg below the knee and a portion of his left calf. A friend pulled him away from the shark and towed him to shore where two beach-goers helped control the bleeding and sought an ambulance.

Authorities monitored the shark for a few hours but rough weather prevented them from catching (but not killing) it. Young Zac is recovering and in good spirits considering what happened.
