Eriphia verrucosa is a non-specific predator of intertidal macroinvertebrates; the main components of berrucosa diet are gastropod and bivalve mollusks, urchins, hermit crabs, and polychaetes Rossi and Parisi, Thus, as for Carcinus maenas Linnaeus,Pachygrapsus marmoratus Fabricius, and other stone crabs, the abundance of E.

In the case of bivalves, the shell of M. The oyster Magallana angulata Lamarck,the mussel Mytilus galloprovincialis Lamarck, and the limpet Patella depressa Pennant, were used in representation of sessile preys, and the hermit crab Clibanarius erythropus Latreille,the toothed top shell Phorcus lineatus da Costa, and the rock sea urchin Paracentrotus lividus Lamarck, as representatives of vagile prey. The biomass of verrucoss eaten prey was derived from its size by using regression lines previously estimated between the size and wet flesh weight of each prey species.

Eriphia verrucosasometimes called the warty crab [3] or yellow crab[4] is a species of crab found in the Black SeaMediterranean Sea and eastern Atlantic Ocean from Brittany to Mauritania and the Azores.

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, Within each sex, crabs presenting externa of S. In terms of mean eaten biomass, the preys most eaten were P.

Life cycle and reproduction in the Cirripedia Rhizocephala. In general, a lower percentage of crab feeding and lower biomass consumption were observed for uninfected females than for the other three crab categories.

Results of the present study also indicated that, although the stone crab E. This limited effect of S. They are predators of intertidal hard-shelled prey such as limpets, mussels, gastropods vergucosa sea urchins Turra et al.

The experiment was carried out under 12L: Prey remains According to the prey remains found in the aquaria, the method by which the crab obtains the flesh of each prey showed several differences Fig. For each of the four sex- Sacculina infestation category, eriphiaa estimated the percentage of crab feeding measured as the percentage of E.

Recreational use of a rocky intertidal reef in Victoria: Both sampling sites were located on rocky platforms with stones and rock pools surrounded by sandy beaches. We thank Royston Snart for the linguistic revision of the English text. Discussion Other large stone eiphia 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, At that time, E.

Differences in the number of crab feeding of each crab category were tested by using the chi-squared test. Category Mean CW range mm 7 F Irrespective of the prey species, uninfected females consistently presented lower percentages of crab feeding and total consumption.

For the six prey species, the shell length was measured as maximum vdrrucosa along the anterior-posterior axis of the shell L. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong. These four crab categories were fed on the six preys offered, but prey remains suggest that the crab obtains the flesh of each prey using different methods of attack.
