Discussion Other large stone crab species, such as the cancrid crab Cancer novaezealandiae Jacquinot,are capable of a flexible foraging behavior, which may allow crabs to maximize feeding efficiency depending on the characteristics of the available prey Creswell and McLay, We hypothesize that the energy cost of eating the latter two preys could be lower than that of other preys, so the infected E.

It is therefore important to know the individual prey preference of crab predators in order to erphia understand their ecological effects on their prey populations and, as a result, on the assemblage composition of intertidal inhabitants.

When they feed on these hard-shelled preys, many crabs are capable of extracting the meat by peeling the shell aperture and thus avoid spending more time and energy in shell crushing Rossi and Parisi,
