• MarsupialCompared with: Monotremes are the other living mammal lineage outside placentals and marsupials.

• MammaliaBroader topic: Monotremes show that mammalian reproduction does not always involve live birth.

• DiprotodontiaCompared with: Monotremes are a distinct mammalian lineage, unlike diprotodontian marsupials.

• Mammalian middle earCompared with: Monotremes show that the three-ossicle arrangement is shared across living mammal groups.

• EutheriaCompared with: Monotremes diverged outside Theria and therefore lie farther from Eutheria than marsupials do.

• Cloaca (anatomy)Broader topic: Monotremes are a notable mammalian lineage that retains a cloaca.

• EchidnaNarrower topic: Echidnas belong to this small mammalian group alongside platypuses.

• DasyuromorphiaCompared with: Monotremes are another distinctive Australasian mammal lineage, but are not marsupials.
