All mammals, including marsupials, have the following characteristics:a body covering of fur, skin or hairsuckle the young on mothers' milkwarm-blooded vertebrates which breathe through lungswith the exception of platypuses and echidnas which are monotremes, or egg laying mammals, all other mammals including marsupials give birth to live young
What phylum are marsupials in?

Koalas and kangaroo are mammals with?
Koalas and kangaroos are both mammals with pouches in which they rear their young. They are marsupials, and almost all species of marsupials have a pouch for this purpose.
Are placental mammals extinct?
No, not all mammals are placental. There are two other groups of mammals: the monotremes and the marsupials.Monotremes are egg-laying mammals, and marsupials are generally pouched mammals, although not all marsupials have fully developed pouches.
Are koala bears mammals?
They are mammals, but they are not bears.Koalas are marsupials, and not even remotely related to bears. Marsupials are an infraclass of mammals, and like all mammals, they feed their young on mothers' milk.
How are marsupials different from other mammals?
A marsupial is a mammal, but it is different to a placental mammal in two main ways.Marsupial young are born very undeveloped, after a short gestation period. Moving purely by instinct, the baby joey (the term for all marsupial young) makes its way to the mother's pouch, where the young joey latches onto a teat, remaining there to continue its growth and development.Many marsupials have the mammary glands enclosed within a protective pouch. Although a mammal with a pouch is always a marsupial, not all marsupials have pouches, for example, the numbat of Western Australia. This is not necessarily a characteristic of marsupials.Marsupials are a kind of mammal. All marsupials are mammals, but not all mammals are marsupials. Marsupials do not have advanced placentas, and have epipubic bones. Epipubic bones are bones which project forwards from the pelvis. In the case of marsupials, these bones support the female's pouch, but there are other mammals which are not marsupials which also have epipubic bones. The excretory and reproductive systems of placental mammals and marsupials are also different.Apart from these characteristics, marsupials have a similar biology to other mammals.
Are there commonalities between neanderthals and marsupials?
Neanderthals and all marsupials are members of the class Mammalia (mammals).
Is the spotted tail Quoll a vertebrate?

Are most mammals placental?
Most mammals are placental. In Australia, however, almost all mammals are marsupials.
Is a whale a marsupial?
Seals are placental mammals, as the young complete their development within the mother's uterus, attached to a placenta. They do not have a pouch like most marsupials, and they do not lay eggs like monotremes.
