Abstract:Shell exchange behavior of intertidal Hawaiian hermit crabs was
observed in the laboratory. Outcomes of 255 shell-related interactions were
analyzed to test the predictive powers of two models of resource exchange. In
the case of intraspecific interactions, the negotiations model (which predicts that
exchanges should occur only when both crabs will gain in shell value) was
superior to an aggression model of resource exchange. In the case of interspecific
interactions, the negotiations model accurately predicted outcome of CalcinusCalcinus
interactions, but poorly predicted outcome of Calcinus-Clibanarius
