Actually... I'd think it would depend on where the fight will happen... Bears are great land creatures and sharks... well, just squirm around the floor in need of air. So I guess sharks suck in land. As opposed to the bears in water, although they do swim, they'd be a sitting duck in water. An easy target for sharks. But bears got haxxxx.... and I don't really like sharks in particular. Wait, why would you even compare creatures not of the same category...? LOL
