Grizzly Bear Facts
- First of all, the powerful and majestic Grizzly Bear actually represents a subspecies of brown bear. At one time there were a total of five separate recognized species of Grizzly Bear, and each had their distinct range.
- There were once two other subspecies in North America alone, yet sadly, the California Grizzly became extinct in 1924. In addition, experts now believe that the Mexican Grizzly Bear has also become extinct.
- Also, individual bears living closer to the coast tend to be larger than those living inland, due to their richer diet, which often leads people to believe that these bears represent separate species.
- Finally, these magnificent animals possess one of the longest natural lifespans of any ursine. Males live an average of 22 years in the wild, while the longer-lived females often reach 26 years of age.

Grizzly Bear Physical Description
One of the most noteworthy facts about the Grizzly Bear remains their tendency to display sexual dimorphism. Males attain an average weight of 790 lb (360 kg), while females rarely exceed 400 lb (180 kg). An average individual has a body length of 6.5 ft (198 cm), and a shoulder height of 3.35 ft (102 cm). Yet exceptional individuals can attain weights of as much as 1,500 lb (680 kg). While coloring ranges from light tan to nearly black, a typical individual displays dark brown fur. The species also remains distinguished by the presence of a pronounced hump on the shoulders. Finally, their powerful claws may be as much as 4 in (10 cm) in length.
