List of placental mammals
Introduction
The class Mammalia (the mammals) is divided into two subclasses based on reproductive techniques: egg laying mammals (the monotremes); and mammals which give live birth. The latter subclass is divided into two infraclasses: pouched mammals (the marsupials); and the placental mammals.
This list contains the placental mammals. For monotremes and marsupials, see List of monotremes and marsupials.

Theria (Template:PronEng, from the Greek θηρίον, wild beast) is a subclass of mammals[1] that give birth to live young without using a shelled egg, including both eutherians (placental mammals) and metatherians (marsupials and their ancestors).
Extent
The subclass includes humans. They have external ears, most can suckle on a nipple, and have an ankle specialized for power and range of motion. Therians are often classified by their specialized dentition.
Almost all currently extant (not extinct) mammals are therians. The only exceptions are the platypus and the echidnas (spiny anteater), both of which are prototherian monotremes.
