This animal may have sharp spines, but it isn't a porcupine! It's one of two types of primitive egg-laying mammals, or monotremes. (The other is the duck-billed platypus.).
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.
