No. I'm not afraid of any rational acting animal, be it predator or otherwise.
You know what a shark will do, how it will act and how to avoid it. The only way to be at risk of shark attack is to create a set of circumstances (in the water, in zones sharks are known or theorised to visit etc).
I'm also not afraid of, and regularly handle, tarantulas, scorpions, constrictors and certain non-lethal venomous snakes. As long as I am smart, well prepared, sober and don't behave like a tit, there is almost zero risk.
All we have to fear is fear itself.
And cobras.
