Any of various egg-laying mammals of the order Monotremata of Australia and New Guinea, whose only living members are the platypus and the echidnas.

mon·o·treme

(mŏn′ə-trēm′)
The most primitive type of living mammal. Monotremes lay eggs, and the females have no teats but provide milk directly through the skin to their young. Monotremes include only the duck-billed platypus, found in Australia and New Guinea, and the echidnas, found only in New Guinea.

WHAT is a monotreme? WHERE was Albert Finney associate artistic director between 1972-5?
"The platypus belongs to the monotreme family, a small group of mammals that lay eggs and produce milk to feed their young.
Twenty species of mammals were recorded, of which one was a monotreme, eight were marsupial and eleven were eutherian (Table 2).
In addition to its obvious physical characteristics--such as webbed feet, rubbery snout, and ears at the jaw's base--the platypus is a venomous monotreme with electroreception, double cones in its eyes, a jaw unique to mammals, and bones in its pectoral girdle that other mammals lack (see Grant 2008).
The evolution of imprinting: chromosomal mapping of orthologues of mammalian imprinted domains in monotreme and marsupial mammals.

At present, sequencing of the whole genome of more than 100 mammalian species, including marsupial and monotreme species is available as well as that of many other vertebrate species including reptiles, birds and fish.
The syntenic X-chromosome region of three marsupial species (wallaby, Macropus eugenii; Tasmanian devil, Sarcophilus harrisii, and opossum, Monodelphis domestica) and one monotreme (platypus, Ornithorhynchus anatinus) genome, focusing on the chromosomal region around the HPRT locus, has been systematically searched and no sequences similar to PLAC1 have been found.
Alongside her own music, Violet has collaborated with pop producer Stumbleine on an EP due for release in early 2014, as well as her debut album, out on Monotreme Records this spring.
But the latest find contradicts that theory because it is much bigger than older, toothed incarnations of the mysterious monotreme. "Discovery of this new species was a shock to us because prior to this, the fossil record suggested that the evolutionary tree of platypuses was a relatively linear one," Archer explained.
If necessity is the mother of invention, then it would appear that even Mother Nature had to respond with novelty in giving us biological adaptations like the platypus (an egg-laying mammal, or monotreme) and the marsupial Kangaroo.
An egg-laying monotreme (a distinction is shares with the echidna), the platypus is found in the fresh water lakes and streams of eastern Australia where it forages for prey with a highly sensitive bird-like bill.
