The exception was the sea urchin P. The experiment was carried out under 12L: For crabs feeding on M. This page was last edited on 6 Mayat Although uninfected females displayed the smallest mean size of tested crab groups, there was no relationship between low percentage of crab feeding and smaller crab size Fig. A relatively high correlation was also observed between predator size and the eriphua consumption and prey size for Cl.
Cheliped morphological variation of the intertidal crab Eriphia verrucosa across verrucsoa of differing exposure to wave action. We hypothesize that the parasite alters host metabolism but that this alteration is more severe in females.
The timestamp is only as accurate as the clock in the camera, and it may be completely wrong. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file.

In the case of bivalves, the shell of M. In terms of mean eaten biomass, the preys most eaten were P. Both sampling sites were located on rocky platforms with stones and rock pools surrounded by sandy beaches. Thus, the smallest size of uninfected females should be associated only with the age of the crab only crabs bearing externa were included in this category.
In term of mean eaten biomass per individual, the prey least eaten was the hermit crab Cl. Handling times, prey size and species selection by Cancer novaezelandiae Jacquinot, feeding on molluscan prey.

According to Rossi and Parisispecimens of E. The carapace width of crabs ANOVA covariate showed a significantly positive effect on the amount of biomass eaten. March 07, ; Accepted: The shell rugosity of prey was also relevant since crabs cannot easily attach to a shell with smooth surface Weigand and Plath, However, the percentage of crab feeding and biomass eaten varied among prey considerably, which suggests a prey preference that could be primarily based on maximizing energy from the potential consumption.
