Quokkas, small marsupials native to Australia, have adapted to arid environments, but they still require water for their survival. While they can tolerate dry conditions better than some other animals, there's no specific information on how long quokkas can live without water. Like many animals, they would become severely dehydrated and eventually succumb to the effects of prolonged water deprivation.
In the wild, quokkas typically obtain water from their food sources, such as vegetation and some fruits, and they may also drink from natural water sources when available. In captivity or during extremely dry conditions, they would need access to water for their health and survival. It's essential to ensure that quokkas have a consistent water source in any environment to keep them healthy.
