Polar Bear VS Grizzly Bear

Polar bear's mass(680 kg or 1300 lb) is higher than the brown mates (270 kg). Same goes for their height. The Arctic specie diet is entirely meat. Grizzly's eat meat, berries and fish. Also they have sharper teeth and are more aggressive than polar bears. The brown mates are small compared to their arctic mates. But have stronger body. It's hard to tell who would win in a fight. Due to global warning the arctic specie might distinct. Grizzlies are safe from that because of higher geographic range and population. Their habitats are already overlapping. But they don't seem to fight. Instead they are matting and forming hybrid specimen.
