“Brown bears otherwise know as grizzlies ...”
All grizzlies are brown bears, but not all brown bears are grizzlies. The grizzly is a North American subspecies of brown bear. The correct scientific name for a grizzly is “brown bear,” but only coastal bears in Alaska and Canada are generally referred to as such, while inland and Arctic bears and those found in the lower 48 States are called grizzly bears.
As a rule coastal bears tend to be larger than the inland bears due to the difference in diets.
