how far can bears smell blood
How many miles away can a great white shark smell blood? saw on discovery or history channel that they can smell one drop of blood from three miles away. have no idea how they can do it. How far away can a polar bear smell seals? They can easily smell a whale carcass 20 miles away or seals up to  6' beneath the snow and ice. This will depend on whether the animal  is dead, which way the wind is goingâ¦, if it is under the ice, if  the polar bear can smell well, etc.
