Quokka  (Setonix brachyurus)

Diurnal: Active during the day.
Dominance hierarchy: The existence of divisions within society, based on the outcome of interactions which show some individuals to be consistently dominant to others.
Marsupial: A diverse group of mammals characterised by their reproduction. The embryo is born 11-35 days after conception. The tiny newborn 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.
Thermoregulatory: The regulation and maintenance of a constant body temperature in mammals.
