"As I was moving in the water, this gator just grabbed my arm," said Lilienthal.

Lilienthal, 37, described the moment when she came face-to-face with the 300-pound alligator in the Wekiva River in early August.

Lilienthal said she was on a third date canoeing when she decided to get in the water and go for a swim. After about 10 minutes in the water, Lilienthal said she was pulled under.

"At one point, it rolled me around and I could feel my arm break. At that point, I realized, 'OK, you're not getting out of this,'" Lilienthal said. "[I] tapped its head. Gator didn't let go of my arm. I pounded it with my fist a little bit."

Lilienthal was pulled to safety, but not before the alligator bit her arm off.

Casey Spencer told WFTV that he and his girlfriend were kayaking nearby and rushed to help Lilienthal escape the gator.

One of those who came to Lilienthal's aid, Joshua Helwig, 19, said he and his girlfriend were canoeing on the river when the heard Lilienthal's screams.

"I just had this overwhelming sense that we had to help her and get her to shore," Helwig said.
