Two special groups of Australian mammals are the monotremes (egg-laying mammals - platypus and echidna) and marsupials (pouched mammals like the kangaroo and wombat).
They are a blue gray. They live a in the water and they are mammals!
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.
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.
Platypuses are one of the 2 mammals that lay eggs. The other is the echidna.
Pouched mammals are called marsupials, they give birth very early and the young live in a special pouch till they are able to live on their own.
Mammals are the only animals that nourish their young with milk, a substance containing proteins, calcium, fat, and Vitamin C.
Most mammals have 4 legs, but some have 2.
what are the four special features of mammals that make them distinct from other animals
Since mammals give live nirth to their young, they will have a womb (uterus) where the baby animal grows until time to be born- and mammary glands (breasts) since mammals nurse their babies.
