Abstract
The stomatopod Gonodactylus bredini is a predatory, aggressive crustacean possessing powerful raptorial appendages capable of inflicting serious injury on conspecifics. These weapons are readily employed during contests for cavities in coral rubble. In this study, we document the incidence of wounds in a population of G. bredini from Panama, determine the influence such injuries have on the behavior and fighting ability of individuals when competing for cavities, and examine associated costs of injury. A major consequence of injury in G. bredini is a severe reduction in fighting ability which in turn can alter the outcome of contests for cavities and the behaviors used by injured animals during such contests. A less immediate, but potentially costly consequence of injury due to increased chances of cannibalism and predation and lost breeding opportunities, is an acceleration in the onset of molt cycles in animals missing raptorial appendages.Keywords
