Extant mammals are divided into three subclasses based on reproductive techniques (monotremes, marsupials, and placentals) consisting of 27 orders. Within each order, families are organized by taxonomic relationship and distinguished by their genus and species.May 19, 2019
Example:- Koala. Although a lot of people call these animals koala bears, they are not actually born but instead are a type of marsupial. ...
Red Kangaroo. ...
Tasmanian Devil. ...
Wallabies. ...
Wombats.

Monotremes are mammals that lay eggs. ... These mammals have a pouch where their young grow and develop. Marsupials are hairy, warm blooded, and produce milk. One of the biggest differences between marsupials and placental mammals is that marsupials give birth quite early and rely less on the nourishment of the placenta.

Answer:

1) Monotremes are mammals that lay eggs. The only monotremes that are alive  today are the spiny anteater, or echidna, and the platypus. These mammals are really different from other  mammals. Their body temperature is lower than most warm-blooded animals, a  feature that has more in common with reptiles. Their name comes from the fact  that they have only one body opening for both wastes and eggs to pass through.

2)  Marsupial mammals give birth to babies that are not completely developed.  The babies are very tiny. The babies then crawl up the fur on the mother's belly  into a pouch on the outside of the mother's abdomen. The babies drink milk from  the mother and continue to develop inside the pouch. Koalas, kangaroos, wallabies,  and opossums are some of the better-known marsupials.

3)A placental mammal develops inside its mother's body until its body systems  can function on their own. The name of this group comes from the placenta, an  organ in pregnant female mammals that passes materials between the mother and  the developing baby. Food and oxygen, carried by blood, pass from the mother to  the baby through the placenta. Most mammals, including humans, are placental  mammals.
