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.).
The platypus and the echidna are both monotremes, that is, egg-laying mammals. There are actually three known species of egg-laying mammals, or monotremes. They are the platyp â¦ us and short-beaked echidna of Australia, and the long-beaked echidna of Papua New Guinea. The echidna is sometimes called the spiny anteater.
