arctos

One is Ursus arctos and the other is Ursus maritimus.

Polar bears (Ursus Maritimus) and Grizzlies (Ursus arctos horribilis) can breed to produce fertile Grolar bears[1].

I have a uarm lite6, but wanted to investigate building an arctos robotic arm to move plates between machines.

Unfortunately, Romanian bears are brown bears (Ursus arctos), not black (Ursus americanus).

Like the old saying doesn't work as well like If it's black, fight back If it's ursus arctos horribilis, lay down If it's white, goodnight.

I've been a few feet away from the Kodiak subspecies ( Ursus arctos middendorff ).

Brown the (surprisingly poorly named) species (Ursus arctos) - yes[2].

Ursus arctos, the scientific name of the brown bear.

>The grizzly bear (Ursus arctos horribilis), also known as the North American brown bear or simply grizzly, is a population or subspecies[2] of the brown bear inhabiting North America.

Across the pond, "brown bear" probably means ursus arctos arctos, a cousin of our own more foul-tempered beasties.

The point is it's clearly a taboo avoidance term, not a derivation of "arctos" which was the real word for bear.

In the US, "brown bear" can mean two things: a black bear with a brown coat ( ursus americanus ), or a grizzly ( ursus arctos horribilis, which makes me giggle every time).

If a pack of grizzly bears break into my house and I scream "Kill the bears!" I'm obviously not calling for genocide against ursus arctos horribilis.
