I'm not much in the know about the differences of the Grizzly, Brown, and Kodiak bears...and if there are any other similar bears. I understand that in BC there's coastal and interior Grizzly, and the coastal to my understanding can be considerably larger. What about the Brown bear, and Kodiak? Are they found mainly in Alaska/Yukon/NWT? What are the differences? Are they all the same, just different sub-species?
