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.).
They are defined by certain characteristics which all mammals share, including: gland â¦ s that produce milk, hair, three bones in the middle ear, and a neocortex in the brain. Most mammals are born live, but there are exceptions. Monotremes, including the echidna and the platypus, lay eggs.Most other mammals give birth to live young mature enough to live outside the womb (called placental mammals).here are two egg-laying mammals. The platypus and the echidna are both egg-laying mammals, or monotremes. They are still classified as mammals be â¦ cause they feed their young on mothers' milk-a characteristic unique to mammals alone. There are just three known species of egg-laying mammals, or monotremes.
