There are three subclasses of mammals: prototheria, metatheria and eutheria. Monotremata is the only order in the prototheria subclass. Monotremes are so different from other mammals that scientists think they may be descended from a separate mammal-like reptilian stock. The duck-billed platypus is in this order.
