Consequently, the marsupials – a group of mammals that raise their young in a pouch , including the macropods , possums and dasyuromorphs – occupy many of the ecological niches placental animals occupy elsewhere in the world.

The platypus — a venomous, egg-laying, duck-billed, amphibious mammal — is one of the strangest creatures in the ...
