Macropus

Macropus is a genus in the family Macropodidae that historically included several large kangaroos. The name derives from Greek makros, meaning “long,” and pous, meaning “foot.” In older classifications Macropus served as a broad catch-all for large macropods. Later taxonomic revisions split many species into separate genera to reflect differences in anatomy and genetics.

Current usage varies by authority. In many classifications, Macropus is restricted to two species: Macropus giganteus, the eastern grey kangaroo, and Macropus fuliginosus, the western grey kangaroo. The red kangaroo, formerly Macropus rufus, is commonly placed in Osphranter, though some sources retain Macropus rufus.

Macropus species are native to Australia, occupying open grasslands, woodlands, and savannas. They are among the continent’s most recognizable marsupials and are adapted to a range of climates, from temperate zones to arid interior regions.

Anatomy and locomotion: Members of the genus have strong hind limbs for hopping and a long tail for balance. They are herbivorous grazers that feed mainly on grasses and leaves. They travel large distances in search of food and water, often moving in organized social groups known as mobs.

Behavior and reproduction: Kangaroos in this group display social structure, male competition, and delayed implantation in females, enabling reproduction to fit resource conditions. While not uniformly endangered, populations are affected by habitat loss and changes in land use across Australia.
