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.).
There are three species of mammals that lay eggs: the Platypus and two species of echidna, the long-beaked echidna of New Guinea and the short-beaked echidna of Australia. (Wi â¦ thin the echidna species, there are two sub-species.) The echidna is sometimes called the spiny anteater.
