List of mammals

The class Mammalia (mammals) is divided into two subclasses based on reproductive techniques: egg-laying mammals (monotremes) and mammals which give live birth (therians). The latter subclass is divided into two infraclasses: pouched mammals (marsupials) and placental mammals (eutherians).

This list is, as yet, incomplete. However for reasons of space, it has been broken into two sections:

• List of placental mammals
• List of monotremes and marsupials (non-placental mammals)
