Kangaroos, koalas, and opossums are examples of what type of mammals?
monotremes
carnivorous
cephalopods
marsupials
By giving birth to tiny embryos, marsupial mothers are at less risk. However, the tiny newborn marsupial may be less likely to survive than a newborn placental mammal. The marsupial embryo completes its growth and development outside the mother’s body in a pouch. It gets milk by sucking on a nipple in the pouch. There are very few living species of marsupials. They include kangaroos, koalas, and opossums. You can see a baby koala peeking out of its mother’s pouch in Figure below .
