It was a Tuesday morning in 2003, Halloween to be exact, and the water at Tunnels Beach was that kind of glassy, perfect blue you only see on postcards from Kauai. 13-year-old Bethany Hamilton was doing what she’d done a thousand times before. She was just hanging out on her board, waiting for a set, her left arm dangling into the cool water. No big deal.
Then everything changed.
The shark that attacked Bethany Hamilton didn't come with a Jaws soundtrack. It was a 14-foot tiger shark, a massive predator that essentially came out of nowhere. There was no splashing. No screaming. Just a sudden, sharp tug and a lot of pressure. Bethany once described it as a "fast vibration." It’s kind of wild to think about, but she didn't even feel the pain immediately because her body went into such deep shock.
The Predator: Why a Tiger Shark?
Tiger sharks are basically the "garbage cans of the ocean." They aren't picky eaters. While Great Whites usually bite and spit things out when they realize a human isn't a fatty seal, tiger sharks tend to finish what they start. This particular shark was a monster. 14 feet is huge. To give you some perspective, that’s about the length of a mid-sized sedan, but with rows of serrated teeth designed to crack turtle shells.
Most people think shark attacks are these long, drawn-out battles. Honestly? This was over in seconds. The shark took her left arm almost up to the shoulder and a chunk of her surfboard. The bite mark on the board was 17 inches across. You’ve probably seen the photos of that board—it looks like a giant took a clean bite out of a cookie.

What Happened to the Shark?
Here’s the part that gets a little murky for some people. Did they catch it? Yeah, they did.
About a week or so after the attack, a local fisherman named Ralph Young caught a 13-foot, 6-inch tiger shark about a mile from where Bethany was hit. He wasn't just some random guy looking for a trophy; he was a friend of the family. He used a massive hook and a smaller shark as bait. When they hauled the thing in, they found surfboard debris in its gut.
The clincher was the jaw.
When investigators compared the shark's teeth to the bite marks on Bethany’s board, it was a perfect match. Every serration lined up. It’s rare to actually "get" the specific shark in these situations, but in this case, there wasn't much doubt. The shark was killed and the remains were disposed of, though the jaws were kept for measurement and evidence.

Survival Against the Odds
Bethany lost about 60% of her blood that morning. It’s a miracle she’s even alive, let alone still surfing. Her best friend’s dad, Holt Blanchard, used a surfboard leash as a tourniquet. That basically saved her life right there.
There's this weird irony to the whole day, too. Her dad, Tom Hamilton, was actually at the hospital that morning for a scheduled knee surgery. He was already in the operating room when the doctor came in and said, "We need this room for a 13-year-old girl who was just attacked by a shark." He had no idea it was his own daughter until a bit later.
The Shark That Attacked Bethany Hamilton: A Legacy of Resilience
People often ask if Bethany is scared of sharks now. Surprisingly, she’s pretty chill about it. She’s said before that she doesn't blame the shark—it was just being a shark. She’s even advocated for shark conservation in some ways, which is a pretty big "adult" move for someone who lost a limb to one.
The attack didn't just create a headline; it created a career. Within 26 days—less than a month!—she was back on a board. She had to learn how to paddle with one arm, which is incredibly difficult because you just end up going in circles if you don't adjust your weight and stroke. She used a custom board with a handle to help her duck dive under waves.

Actionable Takeaways for Surfers and Ocean Lovers
If you're heading into the water, you don't need to live in fear of the shark that attacked Bethany Hamilton, but you should be smart. Tiger sharks are most active at "grey light"—dawn and dusk. Tunnels Beach, where the attack happened, is also known for having a lot of turtles, which are a tiger shark's favorite snack.
- Avoid Murky Water: Sharks love low visibility. If there’s been a big storm and the water looks like chocolate milk, stay out.
- Don't Surf Alone: If Bethany had been by herself, she probably wouldn't have made it back to the beach.
- Look for Wildlife Signs: If you see tons of turtles or fish jumping like crazy, something might be chasing them.
- Know Basic First Aid: Carrying a tourniquet in your car or knowing how to use a leash as one isn't "overkill"—it's a literal life-saver.
The story of the shark that bit Bethany Hamilton is ultimately less about the predator and more about what happened after. She didn't just survive; she dominated. She went on to win national titles and surf some of the biggest waves in the world, like Jaws in Maui. It's a reminder that a "bad day at the office" is relative.
If you want to see the actual surfboard from that day, it’s currently on display at the California Surf Museum in Oceanside. Seeing that 17-inch bite in person really puts the power of a 14-foot tiger shark into perspective.
