Placentals

Mamalia Eutheria - Placentals/Placental Mammals

Distinguishing Features: Mammals that give birth to live young, and the fetus develops in the mother's uterus. The placenta nourishes the fetus until it is born. 
Placental mammals differ from marsupials in that the placentae of marsupials does not last as long nor is as significant to the nourishment of the fetus.

Examples: Armadillo, Whales, Humans
