All extant mammals have some form of hair. No non-mammals have hair. Mammals have warm-blood. Non-mammals, with the exception of birds, are cold-blooded. Reptiles and birds have scales, but amphibians do not. Sponges do not have hearts or vertebrae.
In short, there is not a whole lot that all non-mammals have in common, except the state of not being a mammal.

What animals are not marsupials?
It would be easier to answer which animals ARE marsupials, and to then conclude that all animals not on that list are not marsupials. Let's take that approach. Marsupials are mammals that tend to give birth to underdeveloped young. The offspring generally live within their mothers' pouches until they've grown out of their incredible fragility. So if it has a pouch, it's most likely a marsupial. Marsupials also are an interesting example within the context of evolution. The infraclass of marsupials only evolved somewhat recently, geologically speaking, and you can therefore find the overwhelming majority of all marsupials in the Australia and New Zealand areas. These islands are quite isolated from other large landmasses, so it makes sense that any class of species that evolved on them would stay relatively isolated on them. Think of an animal. If it has no pouch and is not native to this corner of the world, chances are very high that it is not a marsupial.
