Burramys parvus is a small, rodentlike marsupial. Both sexes are about 110mm in head and body length, with males being slightly longer and heavier than females. The tail of B. parvus is prehensile, ranging from 140mm in females to 148mm in males (Strahan 1983). The fur is fine, but dense. The dorsal side is grey, with a darker section at the back and head midline. The ventral surface is light cream, with males developing a bright fawn-orange in breeding season. The forepaws are dexterous, easily able to manipulate food, while on the hindfoot the hallux aids in climbing (Broome and Mansergh 1994).
