What function does the hard outer shell, or carapace, of the yabby serve?
Answer
Serves as armor for vital components beneath
The *Cherax destructor*, being an arthropod, relies on an exoskeleton for structural support and protection. The hard outer shell specifically covering the anterior part of the body is termed the carapace. This rigid structure functions fundamentally as armor, providing comprehensive physical defense for the complex and essential internal organs housed within the cephalothorax. While the yabby's internal systems manage processes like osmotic regulation and gas exchange through specialized surfaces (gills or lungs), the carapace itself is structurally dedicated to shielding these vital, underlying biological machinery from external damage, predation attempts, and environmental abrasion.
