Not even a weapon, or anything? You're fukked either way
I'll take the Tiger. Atleast I'm on land and can see it coming. I'm not sure what I would do but atleast I can do something.
Against a shark I'm just floating there waiting for it to bite my leg off. Then once it bites me its gonna go in a blood frenzy and lose it fukkin mind. That's when shyt gets real.
No, you most likely won't. Tigers are ambush hunters.
You'll be walking along in some wooded area, minding your own business, perhaps wondering why it got so quiet all of a sudden. And then the last thing you see before you get pounced on and your neck snapped/jugular punctured/strangled is a flash of orange and black...
Incidentally, tigers (especially bengal tigers) murk more people than any other wild mammal
