Which two regions define the native range of the genus *Cherax*?
Answer
Australia and New Guinea
The genus level of classification provides a narrower focus on the evolutionary group to which the organism belongs. The genus *Cherax*, which encompasses the Common Yabby (*C. destructor*), the White Yabby (*C. albidus*), and the Redclaw (*C. quadricarinatus*), is specifically native to Australia and New Guinea. While the family Parastacidae is rooted in broader Gondwanan remnants, the genus *Cherax* itself is geographically confined to these two islands. This localized distribution is important when assessing risks related to the introduction of these species outside their natural range, as their ecological requirements are highly specific to these regions.
