The Grizzly Bear (Ursus arctos horribilis), less commonly known as the silvertip bear, is a large subspecies of brown bear inhabiting North America. Scientists generally do not use the name grizzly bear, but call it the North American brown bear. Grizzlies are from the family Ursidae mostly related to pandas, polar bears, sun bears etc. these bears need lot of space the cubs and moms are fine but bulls nah Bull Bears (big male bears) are extremely dangerous even to humans and to the cubs. Grizzlies are expert fish catchers just like American Black Bears, moms are always protective of their cubs, they are omnivores meaning they eat anything like pizzas, bugs, chips or their fave food Honey cause grizzly bears sometimes go into the beehive and use their claws for honey they also eat huckleberries. Grizzly bears catch fish by their jaws their jaws are like stapler teeth holding good ol salmons. Cubs can climb pretty good cause they are lightweight cuties their claws are good for climbing on trees but once they grow up their climbing ability is gone.
