Detailed explanation-1: -There are only five living monotreme species: the duck-billed platypus and four species of echidna (also known as spiny anteaters). All of them are found only in Australia and New Guinea.
Detailed explanation-2: -Monotremes are typified by structural differences in their brains, jaws, digestive tract, reproductive tract, and other body parts, compared to the more common mammalian types. In addition, they lay eggs rather than bearing live young, but, like all mammals, the female monotremes nurse their young with milk.
Detailed explanation-3: -Only two kinds of egg-laying mammals are left on the planet today-the duck-billed platypus and the echidna, or spiny anteater.
