Grizzly vs Brown Bear
Verdict: They are the same species, Ursus arctos. Grizzly usually means an inland bear, while brown bear usually means a larger coastal bear with access to salmon. The difference is geography and size.
All brown and grizzly bears in North America belong to one species, Ursus arctos. The names are historic. The Lewis and Clark expedition popularized grizzly, while coastal people used coastal brown bear. Alaska Department of Fish and Game uses both, with grizzly more common inland and in the north.
In practice, coastal bears with plenty of salmon are bigger, and inland bears with limited marine food are smaller. Kodiak bears are a distinct subspecies, with males that can top 1,500 pounds. Both have the same field marks, including a shoulder hump, a dished face, short round ears and long claws, so the name tells you about place more than anatomy.

When you are looking at which
Grizzly
- A bear seen inland or in northern Alaska, with limited access to marine food.
- A moderate-sized brown bear with a shoulder hump, in a place where people say grizzly.
- A bear in inland Alaska where salmon runs do not reach.
- A bear that looks the same as a coastal bear but a bit smaller.
Brown Bear
- A very large bear along the Alaska coast or at a salmon stream.
- A bear locals call a coastal brown bear, from Southeast Alaska to Bristol Bay.
- A huge, broad-headed bear on Kodiak Island, which is a distinct subspecies.
- A bear feeding on salmon, with heavy build and massive weight.
How this works
The quiz uses place, size, food access, the local name and Kodiak Island. Each answer points toward grizzly or brown bear, and the result summarizes the leaning. The question is really about which name suits a place, so the quiz weights the setting and food access over anatomy.
Because these are one species, the quiz cannot separate them by anatomy. The result tells you which label usage fits best. Bears vary with age, season and individual, so size alone is only a hint. Individual bears of the same species vary a lot, and a bear in a photo cannot be sized well without a reference object.
Where these numbers come from
The figures and defaults on this page are based on:
- National Park Service: Bear Identification, Shoulder hump, face, ears, claws, size and the grizzly versus brown naming (checked October 2026)
- Alaska Department of Fish and Game: A Bear by Any Other Name, One species, naming history, regional usage and Kodiak bears (checked October 2026)

Frequently asked questions
Is a grizzly a type of brown bear?
Yes. Both are the same species, Ursus arctos. Grizzly is the name usually used for inland bears, and brown bear for coastal bears.
Which is bigger, a grizzly or a brown bear?
Coastal brown bears are generally larger because they have access to marine food like salmon. Kodiak bears, a subspecies, can have males over 1,500 pounds.
How do I tell a grizzly from a black bear?
Grizzlies have a distinct shoulder hump, a dished face, short round ears and claws 2 to 4 inches long. Black bears have a flat back, a straight face profile, taller ears and shorter, curved claws.
Why is it called a grizzly?
The Lewis and Clark expedition settled on grizzly for the bears they met, and the name spread after George Ord's 1815 scientific description. Early 20th-century experts proposed 78 species, but that view was later rejected.
