From this story on sun-sentinel.com:
Great white sharks are a rarity in Florida, so when a shark ate a butterflied bonito on a kite line Tuesday morning off Fort Lauderdale, the crew on Hooked Up figured it had to be a bull shark. It wasn't until almost two hours later that Capt. Greg McCauley realized that his four anglers had been fighting a great white estimated at 131/2 feet and 800-1,000 pounds. "No one knew what it was until we got it to the boat," said Capt. Taco Perez, who owns the Fort Lauderdale charter boat. "I've been fishing here since 1969 and Greg and I saw one three years ago. "It's so darn uncommon. We're pretty excited about it."
