Barracudas still have that fearsome look. I used to have an uncomfortable feeling when they were very close to me. I know now that they see me as a large predator and they only come to check whether there are some remains of my prey.
Carrying shiny objects is not a good idea as they might catch the barracuda's attention as they resemble prey to them.
This barracuda was filmed just before sunset at the edge of ambient light and we felt quite comfortable next to each other.
