Plato Users: Reproduction and Development (monotremes, placentals, etc.)
Marsupials, monotremes, and placentals are all types of mammals. To qualify as a mammal, an animal has to be warm blooded, have hair, and produce milk for its young. Alligators do not fit any of those criteria, because they are reptiles, not mammals. So they are not marsupials, monotremes, or placentals.
