Two adult grizzly bears play fight in a river. The bears are “jawing,” a behavior which can look deadly but actually involves nothing more than the bears showing off their fearsome teeth. Bears will open and close their jaws at rivals in a display of power. Often the bear who can open his jaws furthest is accepted as the alpha male. This behavior is often completely silent.
Grizzly bears, also known as brown bears, are usually solitary creatures. When two unrelated bears come into contact with each other, they are usually not very friendly. Sibling grizzly bears play fight all the time as they grow up, learning fighting skills for later in life.
