The quokka is a small marsupial that has achieved global fame as the 'world's happiest animal' due to its perpetually smiling facial expression. These cat-sized macropods are native to Western Australia's Rottnest Island and small mainland populations, where they have become a social media sensation thanks to their seemingly photogenic grins. Quokkas are actually nocturnal herbivores that spend their days sleeping in dense vegetation and emerge at night to feed on grasses, leaves, and bark. Their friendly demeanor toward humans is actually a survival adaptation - they evolved without natural predators and consequently lack fear responses. Despite their adorable appearance, quokkas are tough survivors capable of going months without water by extracting moisture from vegetation and storing fat in their tails during lean periods.

- Can survive months without water by extracting moisture from plants
- Stores fat in tail during lean periods like a camel's hump

Conservation Status
Listed as Vulnerable by the IUCN, quokka populations have declined significantly from historic levels. Mainland populations face threats from habitat loss, predation by foxes and cats, and altered fire regimes. Rottnest Island populations are more secure but face risks from climate change and disease. Conservation efforts include predator control programs, habitat restoration, and monitoring of disease outbreaks. Their popularity as tourist attractions has helped raise awareness but also creates risks from human interaction.
