What is the difference between a grizzly bear and a sun bear?

Grizzly bears, primarily found in North America, are large and robust with a distinctive hump on their shoulders, while sun bears, native to Southeast Asia, are much smaller with a sleek body and short legs. Sun bears have a unique orange-yellow crescent mark on their chest and a primarily insectivorous diet, feeding on termites and honey, whereas grizzly bears are omnivorous, consuming a wider range of foods, including fish and plants. Additionally, grizzly bears are often more aggressive and territorial compared to the more timid sun bears.
