The animals here are listed alphabetically by common name.

A few things to keep in mind when viewing the images below: 

1. Males and females of the same species don’t always look the same;
2. adults and juveniles of the same species don’t always look the same;
3. some species look the same as other species and can only be differentiated from one another by dental or DNA analysis; and
4. species may have summer and winter coats.

The names listed under the image* of the animal are, to the best of my knowledge, current and correct.  Some of the common names, as well as the scientific names, may differ from what is listed on the Range Maps and Life History Account sheets.  Names change as taxonomy continues to shift in all fields of biology!
