About Trichosurus johnstonii (Ramsay, 1888)
Coppery brushtail possums, with the scientific name Trichosurus johnstonii (Ramsay, 1888), have a typical body length of 40โ49 cm (16โ19 in) and a weight of 1.2โ1.8 kg (2.6โ4.0 lb). Males of this species are larger and heavier than females. Like the common brushtail possum, coppery brushtail possums are nocturnal and live in dens, which are most often tree hollows. Even during their active nighttime period, coppery brushtail possums spend half of their time resting to conserve energy, and devote the other half to foraging. Feeding experiments have shown that when selecting food, these possums often tend to choose a mixture of plant materials whose detoxification requirements are correlated or independent, rather than contradictory. This selection pattern maximizes the possums' ability to process harmful plant byproducts. For social dominance among individual coppery brushtail possums, females rank above males, and larger individuals rank above smaller individuals.
