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.).
Mammals are a diverse group of organisms, where the majority of them develop their offspring within the uterus of the mother, though exceptions are noted. For example, monotremes lay eggs, like their common ancestors the reptiles and birds.
