What are monotremes marsupials and placental mammals?
They are placentals, monotremes, and marsupials. The babies of placentals are developed inside the mother’s womb. The main difference between monotremes and marsupials is that monotremes lay eggs whereas marsupials give birth to the live young ones that further develop inside a pouch of the mother’s body.

What is the difference between monotremes and marsupials?
• All marsupials have pouches, but not all the monotremes do have it. • Monotremes lay eggs but not marsupials. • Monotremes have a subnormal temperature and a lower metabolic rate compared to marsupials. • There are almost 500 species of marsupials, but the number of monotreme species is only five.

The monotremes (short beaked echidna, long beaked echidna, platypus) are testicond seasonal breeding mammals that exhibit some characteristics of the reproductive tract found in reptiles (e.g. testicond, presence of a cloaca).[15] The fully developed monotreme epididymis exhibits two anatomical regions,[2]similar to some reptiles.
