Below are all the species from which yopu must choose 20 as a group for this assignment. Follow the guidelines in the handout. This list is presented as a classification. Marsupials (Metatheria) and placentals (Eutheria) are the two main subclasses in mammals. To see a picture of representatives of each "species", just click on the links.

Species are indented two tabs, except for cetaceans, megabats, and muroid rodents (well-defined clades within orders that have more species) which are tabbed one more.
