What environmental realities typically cap the lifespan of wild *Cherax destructor* around four to six years?

Answer

Drought, predation, and fluctuating water quality

The existence of a yabby in its natural habitat across Australian dams and rivers exposes it to numerous unpredictable and severe environmental hazards that shorten its life compared to a managed captive setting. The primary factors that contribute to capping their lifespan around the four to six year mark are the harsh realities inherent to the wild ecosystem. These include the threat of drought, which drastically lowers water levels and concentrates toxins; predation from larger aquatic or terrestrial animals; and general fluctuations in water quality that occur outside of human control. These risks, which are largely mitigated in an aquarium, define the lower end of the species' longevity potential.
