Description
The quokka is a small macropod, measuring between 40 to 54 centimeters in length, with a tail length of 24 to 31 centimeters, and weighing approximately 2.7 to 4.2 kilograms. It has a stocky build, rounded ears, and coarse brown fur that fades to a lighter shade underneath. Unlike larger relatives such as kangaroos, quokkas can climb small trees and shrubs up to 1.5 meters in search of food. Their average lifespan is about 10 years. (en.wikipedia.org)
Habitat and Distribution
Quokkas are endemic to southwestern Australia, with their range including the mainland and several offshore islands. Notably, they inhabit Rottnest Island near Perth and Bald Island near Albany. On the mainland, they prefer areas with dense vegetation, such as swamps and forests, which provide both food and shelter from predators. (en.wikipedia.org)
Diet and Behavior
As nocturnal herbivores, quokkas feed on a variety of vegetation, including grasses, leaves, and stems. They have been observed climbing up to 1.5 meters to reach food sources. Quokkas can survive in areas with limited freshwater by obtaining moisture from their food. They are known to chew their cud, similar to ruminants like cows. (en.wikipedia.org)
Reproduction
Quokkas have a promiscuous mating system. After a gestation period of about 27 days, females give birth to a single joey, which remains in the mother's pouch for approximately six months. Females can give birth twice a year and may produce up to 17 joeys over their lifetime. Notably, quokkas exhibit embryonic diapause, where a fertilized egg's development is paused until the previous joey leaves the pouch. (en.wikipedia.org)
Conservation Status
The International Union for Conservation of Nature (IUCN) lists the quokka as a vulnerable species. Their populations have declined due to habitat loss, predation by introduced species such as foxes and cats, and changes in fire regimes. Conservation efforts include habitat restoration, predator control, and public education to protect remaining populations. (en.wikipedia.org)
Human Interaction
Quokkas have gained popularity for their friendly appearance and are often referred to as "the world's happiest animals." This has led to a rise in tourism, particularly on Rottnest Island. However, interactions with humans can pose risks to quokkas, including the transmission of diseases and dependency on human-provided food. Feeding and handling quokkas are discouraged to ensure their health and safety. (en.wikipedia.org)
