The only two egg-laying mammals in existence are the platypus and the echidna, which are classed as monotremes. 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.
