There are few things in life that are absolute and universal. One of those things is not wanting to be anywhere near a great white shark with blood pouring from your foot in open water. Generally speaking, humans don't fare well in aquatic battles with the toothy killer. Luckily for college student Tyler McQuillen, he was an exception.
McQuillen was diving near Santa Barbara on Sept. 1 — and filming the dive on his GoPro — when a great white shark attacked him from behind, ripping off one of his flippers. As it approached his side, he fended it off briefly. Then shark circled back again. He was able to fend it off once more with the spear gun that he was carrying the GoPro on. After that, the shark backed off.
"I gave him a nice little jab," McQuillen told CBS 8.
He managed to swim back to safety without any further attacks. He made it back in time to warn friends, knowing that he was bleeding from his foot and had some of the shark's blood on his spear. "I saw blood around me," he wrote on YouTube, "and wasn't sure where it was from, so I swam as fast as I could back to shore."
