This Web site was developed by Rick Gillis and Roger Haro of the University of Wisconsin-La Crosse Biology Department as a study guide for Animal Biology students. By navigating through the self tests that include images of animal cells, tissues, and structures, students can review or learn about the animal kingdom. Organisms ranging from protozoa to vertebrates are included in three self tests. Information is further organized into 9 laboratory sessions that are easy to access through the table of contents.
