Southern marsupial mole  (Notoryctes typhlops)

Diurnal: Active during the day.
Marsupial: A diverse group of mammals characterised by their reproduction. The embryo is born 11-35 days after conception. The tiny neonate crawls into the marsupium (pouch) and attaches to a teat where it stays for a variable amount of time. They also differ from placental mammals in their dentition.
Nocturnal: Active at night.
Placental: Group of mammals characterised by their reproduction and physiological characteristics. The embryo is retained in the uterus, and born in an advanced state of development.
Vestigial: A characteristic often reduced in form, with little or no contemporary use, but derived from one which was useful and well developed in an ancestral form.
