Monotremata
n.
order of Australian egg-laying mammals (Zoology)
Monotreme
Monotremes 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.
