LAKE CLARK NATIONAL PARK, ALASKA, USA: The bears fight over the fish. WITNESS the epic moment two four-hundred-pound brown bears made the ground ?SHAKE? whilst brawling over a salmon. The incredible pictures showed the two colossal seven-foot-tall bears as they launched their bodies at each other as they fought over the fishy meal. In another image, the victorious mother bear was pictured walking away with her salmon prize before giving the fish to her nearby cubs to eat. The incredible images were taken at Lake Clark National Park, Alaska, USA, by photographer and bear viewing guide Eric Fisher (31) from Shaker Heights, Ohio, USA, using his Canon 7D Mark II camera with and Sigma 150-600mm lens. Eric got within an incredible 75-feet distance from the action in which he was able to hear the ground ?shake.' Mediadrumimages/ Eric Fisher Photography
