Yes. They are the only surviving animals to give birth and have hair. In prehistoric times, marine reptiles from the Mezoic Era gave birth. In a periodic boundary near and in this Era, animals called thecodonts, or "mammal-like reptiles", had hair, too.
Two special groups of Australian mammals are the monotremes (egg-laying mammals - platypus and echidna) and marsupials (pouched mammals like the kangaroo and wombat).
The platypus and the Echidna. They are special because they are the only mammals that lay eggs but suckle their young with mother's milk.

Koalas and Kangaroos belong to the group of animals known as Marsupials. These mammals are characterized by having special pouches in which they keep their young.

Only mammals can produce milk, which newborn baby mammals drink in order to grow. Milk contains fat, vitamins, calcium, and protein.
paste special is special i'm saying anything
Monotremes are special because they are a very small group of mammals which lay eggs. Most mammals give live birth, but monotremes lay soft-shelled, leathery eggs in order to reproduce.
Mammals give milk to their young, have some type of hair sometime in their lives, breathe air, and do not have feathers or gills.
