Now, he has a great story to tell.
"I saw blood in the water," said Austin.
He didn't realize what was going on until he looked around him. Austin says he started screaming and made it to shore, where his mother was waiting.
“I turned this way and I heard [father] Adam say, ‘Why is Austin screaming?’” Shauna Moore said. “We turned and looked at the water and he had a very terrified scream as he was walking.”
Austin was rushed to Halifax Health in in Daytona Beach, where he underwent two hours of surgery to fix two tendons.
After surgery, the family wanted to know just how many stiches he received.
"We asked the doctor .. and he just said 'A lot,'" Shauna Moore said.
"I'm lucky because I still have my foot," Austin Moore said.
Austin say he still loves sharks. Just not the one that bit him.
Austin says his leg has to stay wrapped up for a few weeks, but he can't wait to get back to school and tell his friends his story.
A shark expert in Gainesville says there have been 17 shark bites this year in Florida — eight of them in Volusia County.
