Which native crayfish species in Western Australia has been critically endangered due to C. destructor introduction?
Answer
Euastacus dharawalus
The ecological success of the introduced yabby (*C. destructor*) creates significant conservation crises in areas where it is not native. In certain regions, such as Western Australia, its aggressive competition for resources like food and habitat has led directly to the decline of indigenous species. Specific documentation points to the profound negative impact on the native crayfish species known as *Euastacus dharawalus*. Due to displacement caused by the highly adaptable and fecund *C. destructor*, *Euastacus dharawalus* has subsequently been classified as critically endangered in its native range, demonstrating the invasive potential of the yabby when introduced outside its natural distribution.
