Monotreme Definition from Encyclopedia Dictionaries & Glossaries
Wikipedia English - The Free Encyclopedia
Monotremes (from the Greek μονός monos "single" + τρῆμα trema "hole", referring to the cloaca) are mammals that lay eggs (Prototheria) instead of giving birth to live young like marsupials (Metatheria) and placental mammals (Eutheria). The only surviving examples of monotremes are all indigenous to Australia and New Guinea, although there is evidence that they were once more widespread. The existing monotreme species are the platypus and four species of echidnas (or spiny anteaters). There is currently some debate regarding monotreme taxonomy. Monotreme young are sometimes called puggles.
