Assuming a bear and a shark of the same weight and maturity level, I would go with the shark. The shark would drag the bear into the water a drown him. The shark would also have tasty bear soup afterwords. :-)
A polar bear wold win vicious shark in a fight
In the ocean, my money would be on the shark. On land, the bear would probably win unless it stuck its head in the sharks mouth.
the polar bear cuz the shark cant fight on lad. OR the shark cuz the bear cant fight in water SO The world may never know.
