Although I've been interested in nature since my childhood, I've never really been too concerned with learning how to differentiate between all the different infraclasses, which are classes within the classes. For example, I would hope anyone could correctly determine the difference between a bird and a fish, but how about telling the different types of fish or birds apart from one another? It may not be too taxing but it's not something I've ever really tried to do, but one infraclass that's always stuck in my mind is that of the marsupials.
All marsupials are mammals but while some mammals give birth as we do and some lay eggs, but marsupials give birth to their young much earlier than either of the other types and raise them to infancy in a handy pouch. This characteristic makes them unique in the animal kingdom and their distribution is also more specific than many other types of animals. The name is most commonly associated with Australia, and indeed many of the mammals living on this continent are marsupials, but they can also be found in South and Central America too. Despite this, the splendid creatures I've selected for this list are all from the bonzer land down under:
