Lumholtz's tree-kangaroo (Dendrolagus lumholtzi) is a heavy-bodied tree-kangaroo found in rain forests of the Atherton Tableland Region of Queensland. Its status is classified as near threatened  by the IUCN, and authorities consider it as rare. It is named after the Norwegian explorer Carl Sofus Lumholtz (1851–1922), who discovered the first specimen in 1883.
It is the smallest of all tree-kangaroos, with males weighing an average of 7.2 kg (16 lbs) and females 5.9 kg (13 lbs). Its head and body length ranges from 480–650 mm, and its tail, 600–740 mm. It has powerful limbs and has short, grizzled grey fur. Its muzzle, toes and tip of tail are black. The Lumholtz's tree-kangaroos colonizes a variety of habitats, so long that it is flourished with food and its structural features are stable and adaptable.
Lumholtz's tree-kangaroo are generally solitary animals, with the exception of male-female mating and the long, intimate mother-joey relationship. Each kangaroo maintains a "home range" and will be hostile towards a member of the same sex that enters it (the one exception seems to be non-hostile encounters between adult males and their male offspring). Thus, the male will protect his own range, and visit the ranges of the females in his group. Mating takes place in episodes of about twenty minutes, and is often quite aggressive.
