Quokkas do not have any specific physical defense mechanisms against predators. Instead, they rely on their speed and agility to escape danger. They can run up to 12 miles per hour and jump up to 3 meters to avoid predators.
Quokkas also have the ability to retreat into thick vegetation or hide in burrows to avoid predators. Additionally, they tend to be active primarily at night, which helps them avoid detection by predators during the day.
However, the biggest threat to quokkas comes from introduced predators such as foxes and feral cats. Efforts are being made to control these predators and protect quokkas in their natural habitats.
