Every Wild Cattle Explained in 32 Minutes

Every Wild Cattle Explained in 32 Minutes American Bison. The comeback king of North America, and honestly, one of the greatest survival stories on the continent. These massive animals can weigh up to 900 kg, basically the size of a small car, but here's what's wild, they can sprint at speeds up to 35 mph despite all that bulk. That's faster than you can drive through most neighborhoods. Their thick skulls aren't just for show either, they can ram through wooden barriers and withstand impacts that would crack bone in most animals. American bison survive in temperature extremes that would kill most mammals, from negative 40 degrees Fahrenheit winters to scorching 100 degree summers. They do this by growing dense winter coats and wallowing in dirt during summer to create protective mud layers.
