Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Different types of mammals are defined by the way their kids develop, in eggs, pouches, or inside the mother. The Spiney Echidna lays eggs so it is a ____ mammal.

A	Placental
B	Marsupial
C	Monotreme
D	None of the above

Explanation:

Detailed explanation-1: -Only two kinds of egg-laying mammals are left on the planet today-the duck-billed platypus and the echidna, or spiny anteater. These odd “monotremes” once dominated Australia, until their pouch-bearing cousins, the marsupials, invaded the land down under 71 million to 54 million years ago and swept them away.

Detailed explanation-2: -Monotremes are mammals that reproduce by laying eggs. The only living monotreme species are the platypus and echidnas (see Figure below and Figure below).

Detailed explanation-3: -Well, marsupials are the kinds of animals that can do this. They are known as pouched mammals, because the adult females have a marsupium, or pouch. Young marsupials (called joeys) do most of their early development outside of their mother’s body, in a pouch.

Detailed explanation-4: -Mammals are divided into three groups-monotremes, marsupials and placentals, all of which have fur, produce milk and are warm-blooded. Monotremes are the platypus and echidnas and the females lay soft-shelled eggs.
