Was she feeding it? Shark bites the hand that fed it?
That happened to me some 25 years ago when I caught a Brown Trout, in attempting to remove the hook, it bit me on the finger and I later got a terrible, painful, infection at the site of the wound which had to be lanced. I didn’t release the Trout though, I later cooked and ate it. This being the pre-internet era, it did not make the news.
