Ali tells a local newspaper that he was closing his father's business, Zack's Pier Plaza in Huntington Beach, on Monday when he saw the ocean was calm and decided to dive for dinner.
He was down about 15 feet going after a smaller lobster when he saw the giant. He says it was too big to grab properly, but it latched onto him, and he wrestled it to shore.
The lobster weighed nearly 18 pounds - even a 5-pounder is considered trophy-sized - and was likely at least 30 years old.
