'Incredibly heroic' fisherman jumps off pier to save sea turtle

There were some tense moments after a sea turtle became entangled in a fishing line off a Florida pier.

"Most likely this animal would have had hundreds of feet of fishing line around him," fisherman Donald Zinn said. "It was wrapped around his neck, one of his fins."
