Perez was out surfing with friends on Halloween. They had been in the waters near the mouth of the Siletz River four about two and a-half hours when it happened.

"I felt a violent blast on the back of the board," said Perez. Lucky for him, he was lying flat on his board with his legs bent and feet up in the air when the shark struck.

It pulled me back and down, but my head didn't go under water. My feet came down on top of it, and I felt this huge rock-hard body, just this big old beast below me."

He quickly swam back to shore, and originally thought a seal had attacked him, but found 2-inch teeth marks on his borrowed surfboard.

According to local surfers, shark activity has been on the rise at popular surf spots along the Oregon coast.

I just got lucky," Perez said. "I happened to have my legs up, and that's it. Otherwise I would have been a pirate for Halloween."
