Bear Anatomy

Apparently, even black bears can possess shoulder humps like grizzlies:

   

   

But I don't think it is so common as those of grizzlies in terms of bears with the feature, but this black bear population features it nonetheless.

Also, from my research about this particular subspecies, they tend to have wider jaw gapes and larger skulls than the average black bear of similar weights:

"The subspecies found on HG /QCI is generally larger than its mainland counterparts with a huge skull and molars, and is only found as a black colour phase. These physical differences are thought to result from retaining characteristics after a long period of isolation during the last ice-age."

This might be the primary black bear population that has quite different shoulder characteristics from other black bears in general. Reply
