Eutherian (Noun)

Mammals having a placenta; all mammals except monotremes and marsupials.

Nouns denoting animals.

The eutherian mammals, which include humans and other placental mammals, have a more complex reproductive system than monotremes and marsupials.
The evolution of the eutherian placenta is thought to have been a key factor in the success of placental mammals.
Eutherian mammals are characterized by the presence of a placenta, which provides nutrients and oxygen to the developing fetus.
The eutherian mammals are a diverse group, ranging from small rodents to large whales and elephants.
In contrast to monotremes and marsupials, eutherian mammals have a longer gestation period and give birth to more developed young.
