Together with the platypus, echidnas are the world's only monotremes, or egg-laying mammals. There are two species of echidnas: the long-beaked echidna, which is confined to the highlands of New Guinea; and. the short-beaked echidna, which lives in Australia and New Guinea.
The platypus and the echidna are both egg-laying mammals, or monotremes. They are still classified as mammals because they feed their young on mothers' milk-a characteristic â¦ 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 (Zaglossus bruijni) of Papua New Guinea.
