The Barracuda short video
This was a very typical moment while diving in Antigua this kind of sized Barracuda would come in close sometimes with friend. Always curious (with friend bi-curious ok bad joke). Am glad I managed to get some video up about it, can't wait to try out my go pro as you can see this is not taken with anything near sophisticated for todays market.
Here is a cool post on what might be happening when a barracuda follows you- https://xcalakmexico.com/snorkeling-barracuda/
