Monotremes are a unique order of mammals that includes only three extant species: the duck-billed platypus (Ornithorynchus anitinus), the short-billed echidna (Tachyglossus aculeatus), and the western long-billed echidna (Zaglossus bruijni).

What type of animal is a monotreme?

platypus
The monotremes are a group of highly specialised egg-laying predatory mammals, containing the platypus and echidnas. There are only five living species of monotreme, contained within two families: Family Ornithorhynchidae: the platypus, a single species in a single genus, Ornithorhynchus anatinus.

Why are monotremes only found in Australia?

Why are monotremes, mammals that lay eggs rather than give birth to live young, only found in the isolated region of Australia and New Guinea? It is the isolation of this region that’s key. 200 million years ago, Australia was situated on the far-reaches of Pangaea, the last supercontinent (Figure 10.3. 1).
