MammalsAll mammals feed their young on mothers' milk, but there is one group of mammals known as monotremes which actually lay eggs. The platypus and echidna are both egg-laying mammals.
Both the echidna and the platypus are mammals that lay eggs. They are in a subclass of their own, the monotremes, which are the egg-laying mammals. In every other respect, they exhibit the characteristics of mammals, such as having fur, being warm-blooded vertebrates and feeding their young on mothers' milk.
