The American Bear
"Look what I found just LAYING in the river! What great luck!"
Well, this is a no-brainer right? In our case, we're looking at the American Black Bear. Patriotic right?
The American Black Bear, is the most commonly found bear in, (Guess.) North America. These beast, are actually America's smallest species of bear, but that doesn't keep them from using your shins as toothpicks after eating you.
American Black Bears can weigh around 300 pounds depending on which coast you're on they can weigh a bit more, or less. Although some of the largest American Black Bears have reached the weight of 880 pounds, so make sure you don't find your way under one. They're known to be able to flip rocks weighing about 318 pounds with a single paw, so yeah, I think they might be able to pick you up with their pinkie-paw.
Well, I know what you're thinking in your head, "Sure he's strong, but can he run as fast as me?" Well shucks, I guess you're right. Oh wait, bears can run 25-30 miles per an hour. Some of the trained "world record breaking" athletics can reach the speeds of 27 mph, so chances are, you're not outrunning this Black Bear.
Lucky for you, American Black Bears tend to be considered relatively "safe". These bears rarely attack during human encounters. They tend to limit themselves to fake charges, swatting the ground angrily, and making loud blowing noises. But that doesn't mean you should charge up at the next bear you see as if you're Chuck Norris or something. If they decide to lay down justice, they will lay down justice.
