In North America, brown bears are often referred to as grizzly bears — because of their grizzled fur
Brown Bear Definition
The brown bear (Ursus arctos) is a large bear species. In North America, brown bears are often referred to as the grizzly bears. The name “grizzly” came from their grizzled appearance due to the long hairs over the shoulders and back. (Ref.1) They have long claws on their front limbs. Their fur is often dark brown in color. Others have a different fur color, ranging from black to light creamy shade. (Ref.1) The typical body length may reach up to 2.8 m (from head to rump) and the weight ranging from 80 kg to more than 600 kg. They exhibit sexual dimorphism. Males are larger than females, about 8% to 10%. (Ref.2)
Brown bears are omnivores. They feed on fruits, insects, invertebrates, fish, and small mammals. (Ref.1) The International Union for Conservation of Nature (IUCN) listed the species as Least-Concern Species. (Ref.2)
