1808_3515 Black Bear
Intense and focused, this bear is ready to pounce on an unsuspecting salmon. (Here's an assumption - that salmon don't suspect. After two years at sea, what can a salmon possibly know about terrestrial predators?) Did the bear see movement, or even smell something through the water barrier? Bears have the most sensitive noses on the planet. How sensitive? A google search produced the following, unverified claims: The average dog's nose is 100 times more sensitive than ours, and a bloodhound's is 300 times. A black bear's nose is 7 times more sensitive than that, or 2,100 times more than a human's. A black bear has been observed moving 18 miles in a straight line to a food source; grizzlies can detect an elk carcass underwater, and polar bears can smell a seal through three feet of pack ice. Draw your own conclusions, but I would suggest that the nose knows.
