Despite home field advantage, the beast succumbed: A spearfisherman armed with only a fishing knife, a speargun, and a snorkel managed to battle a 12-foot tiger shark to the death in the Gulf of Mexico, the New York Post reports. Craig Clasen was attacked by the huge creature while hunting tuna. The shark circled him and a fellow fisherman aggressively, then barreled toward Clasen. Upon seeing the shark, the duo recognized they were on the beast’s menu. The showdown lasted two hours, with Clasen spearing the shark seven times before finishing it off with a long hunting knife. Clasen, for his part, felt no pride at the kill. “This was one of the most remorseful moments I have ever had in all of my years in hunting and fishing,” he said.
