Quizplus · Accepted Answer

Eutheria, also known as placental mammals, are characterized by having embryos that develop for a longer period within the uterus and are nourished through the placenta rather than through egg yolk or directly from the mother's nipples post-birth. This group also exhibits prolonged maternal care after the young have left the placenta, distinguishing them from marsupials and monotremes.
