Two things not found in marsupials which are found in monotremes:
1. Monotremes lay eggs, although they are mammals.
2. Monotremes have a single opening, or cloaca, for passing waste and for the reproductive purposes of both males and females. Marsupials have separate urinary and genital tracts, but the genital tract is separate, but there is still an external remnant of the original cloaca.
3. Monotremes have alternative to teeth - the platypus has a grinding plate and the echidna has a long, sticky tongue so does not need teeth.

What marsupials lay eggs?
Marsupials do not lay eggs. They give birth to live (although undeveloped) young.The platypus and the echidnaare both egg-laying mammals, or monotremes, not marsupials. They are still classified as mammals because they feed their young on mothers' milk - a characteristic unique to mammals alone.There are just three known species of egg-laying mammals, or monotremes. They are the platypus and short-beaked echidna (Tachyglossus aculeatus) of Australia, and the long-beaked echidna (Zaglosssus bruijni) of Papua New Guinea. The echidna is sometimes called the spiny anteater, and there are several sub-species of the long-beaked echidna: the Western long-beaked echidna, Sir David's long-beaked echidna and the Eastern long-beaked echidna.

Mammals and marsupials have what main characteristic that identify them?
An animal is a mammal if: 1. It has a backbone and skeleton. 2. It is warm-blooded. 3. It has hair. 4. It gives live birth (except for the five monotremes). 5. The females have mammary glands.

Why are there so many species of marsupial mammals in Australia?
The main theory for this seems to be that, when the continents shifted and separated thousands of years ago, the Australian continent was left without any large predators. Unlike other continents, which most likely had marsupials and monotremes as well, the Australian continent provided a safe haven for the many unique species to grow and proliferate without being wiped out by larger species.
