Setonix

Setonix is a genus of marsupial native to southwestern Australia, containing a single extant species, the quokka (*Setonix brachyurus*). The quokka is a small, herbivorous mammal belonging to the family Macropodidae, which also includes kangaroos and wallabies. It is one of the few marsupials that is diurnal, active during the day, and is known for its distinctive appearance and friendly demeanor.

Quokkas are typically 40–55 centimeters (16–22 inches) long, with a short, bushy tail and a compact body weighing between 2.5 and 5 kilograms (5.5–11 pounds). Their fur is soft and dense, varying in color from reddish-brown to grayish-brown, with a lighter underbelly. Their most notable feature is their broad, rounded face, large eyes, and a short, upturned nose. Quokkas are often described as having a perpetual smile due to their facial structure.

The quokka inhabits a range of coastal and island environments, including heathlands, woodlands, and shrublands. Historically, they were found across much of southwestern Australia, but habitat destruction and predation by introduced species have reduced their range. Today, they are primarily found on Rottnest Island and a few other islands off the coast of Western Australia, as well as in protected areas on the mainland.

Quokkas are social animals, often seen in small groups or pairs. They are herbivores, feeding primarily on grasses, leaves, and shrubs. Despite their small size, they are strong swimmers and climbers, capable of navigating rocky terrain and water bodies with ease. Their conservation status is classified as "Near Threatened" due to ongoing threats from habitat loss, vehicle strikes, and predation by foxes and cats.

The quokka is a popular tourist attraction, particularly on Rottnest Island, where visitors often interact with them. However, their increasing exposure to humans has raised concerns about stress and disease transmission. Conservation efforts focus on habitat protection, predator control, and public awareness to ensure the long-term survival of this unique and endearing marsupial.
