Placentalia
Placentalia ("Placentals") is one of the three subdivisions of the class of animals Mammalia; the other two are Monotremata and Marsupialia. The placentals are primarily distinguished from other mammals in that the fetus is carried in the uterus of its mother where it is nourished via a placenta, until the live birth of a fully developed offspring occurs.
