The Platypus, the most well known monotreme. Monotremes are a group of mammals that form the order Monotremata. Monotremes are the only mammals that lay eggs, but they also feed their babies with milk. The word 'monotreme' refers to their common rear opening, the cloaca. In amphibia, reptiles, birds and probably all early tetrapods, there is a common opening for urine, reproduction and faeces.
Egg-laying Mammals. There are only five living monotreme species: the duck-billed platypus and four species of echidna (also known as spiny anteaters). All of them are found only in Australia and New Guinea. Monotremes are not a very diverse group today, and there has not been much fossil information known until rather recently. In some ways, monotremes are very primitive for mammals because, like reptiles and birds, they lay eggs rather than having live birth. In a number of other respects, monotremes are rather derived, having highly modified snouts or beaks, and modern adult monotremes have no teeth.
