I've met literally dozens of people who talk about their close brush with a barracuda while diving.
They are a minimal threat but they look kind of scary so people always always think that they had a close call with one when the barracuda is just doing what they do which is checking out a human who might hand them a fish.
It always makes me chuckle because I hear people tell their barracudas stories and they always sound the exact same. At no point were they in any danger but they really think they were.
