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.).

Marsupials, like all mammals, are also â¦ warm-blooded vertebrates which breathe through lungs. They have a covering of fur or hair over their skin. They have a four-chambered heart.
