Apart from the obvious fact that the duck universe is swarming with anthropomorphic ducks, dogs, bears, and so on, almost all of Carl Barks' stories contain a certain number of so-called dumb animals, i.e. animals that do not think, talk, and behave as the primary characters. They are usually seen in the background or as helpers to our heroes, but once in a while they obtain leading roles in the stories.
In the sub-pages you will find a variety of story examples with different animals. In order to be considered in the sub-pages a particular animal must either play a major contributing role or have a substantial impact on the plot. Example: The story with the bears in FC0178 Christmas on Bear Mountain is admitted because of their substantial roles, but the story with Glittering Goldie's much less important guardian bear in FC0456 Back to the Klondike is not, because it only plays a small and dispensable role.

The sub-pages demonstrate Barks' colossal and highly impressive inventiveness in dreaming up stories with so many species, but they still just represent examples (10 to each page arranged in chronological order after dates of publishing).
