“…Mortality in limpet populations due to crab predation has previously been shown at the lower shore at Mount Batten (Silva et al 2008), a shore used in the present study, and in this region, crabs have been shown to attack limpets frequently (Thompson et al 2000). This may also influence intra-specific competition for space or food resources among these grazers (Boaventura et al 2002).…”

“…Crab abundance and predation effects have been correlated in previous studies, whereby prey with stronger shells were present at sites where crabs were more abundant (Vermeij 1976, Hughes & Seed 1981, Yamada & Boulding 1998. Crabs exert significant control on the abundance of limpets on moderately sheltered shores in southwest Britain (Silva et al 2008). Limpets are known to have a key influence on intertidal assemblages (Hawkins & Hartnoll 1983, Jenkins et al 2005, Coleman et al 2006, and also to be less abundant at sheltered than at exposed locations (Hawkins & Hartnoll 1983, Jenkins et al 1999.…”

“…C. maenas that were observed at low tide at night were feeding on limpets, and stomachcontent analysis of individuals captured at high tide indicated that limpets composed ~40% of the C. maenas diet. Hence, limpets would appear to be subject to considerable predation by crabs at night during both lowand high-water periods (see also Silva et al 2008). …”

Linkages between predators and their prey across the subtidal-intertidal boundary remain relatively unexplored. The influence of tidal phase, tidal height and wave exposure on the abundance, population structure and stomach contents of mobile predatory crabs was examined on rocky shores in southwest Britain. Crabs were sampled both during the day and at night using traps deployed at high tide and by direct observation during low tide. Carcinus maenas (L.), Necora puber (L.) and Cancer pagurus (L.) were the most abundant species, being mainly active during nocturnal high tides. C. maenas was the only species that was active during nocturnal low tides, when it was observed mainly on the lower shore feeding on limpets. Individuals of all 3 species sampled during high tide were considerably larger than those sampled during low tide. Thus, sampling crab populations at low tide is likely to underestimate abundance and the extent of predation by crabs on rockyshore assemblages. During immersion, the relative abundance of each species was influenced by exposure to wave action and tidal elevation. All species were more abundant on the lower shore; C. maenas and N. puber were more abundant in sheltered locations, while C. pagurus was more abundant in exposed locations. Analyses of stomach contents from individuals captured at high tide revealed that chitons and limpets were the most common hard-shell prey taxa in the diet of these predators. The relative abundance of prey in gut contents was, however, not correlated with patterns of prey abundance. Our study indicates the importance of crabs as key intertidal predators and illustrates the strong trophic linkages between the subtidal and intertidal zones, which is likely to be a key factor influencing community structure on European shores.

“…Top predators as E. verrucosa could play a significant role in structuring intertidal communities (Rilov and Schiel, 2006;Silva et al, 2010). Indeed, using predatorexclusion experiments, Silva et al (2008) observed a significant reduction of limpet densities when crabs predation was occurring. Conversely, Brazão et al (2009) failed to detect a significant effect from E.…”

“…Crabs are highly mobile and are known to have an important role in structuring assemblages on rocky shores worldwide (Behrens Yamada and Boulding, 1996;Rilov and Schiel, 2006;Silva et al, 2008;Forsstrom et al, 2015). They are predators of intertidal hard-shelled prey such as limpets, mussels, gastropods and sea urchins (Turra et al, 2005;Silva et al, 2010;Laitano et al 2013).…”

Predatory behavior of the crab Eriphia verrucosa (Forskål, 1775) on the oyster Magallana angulata (Lamarck, 1819), the mussel Mytilus galloprovincialis Lamarck, 1819, the limpet Patella depressa Pennant, 1777, the hermit crab Clibanarius erythropus (Latreille, 1818), the gastropod Phorcus lineatus (da Costa, 1778) and the sea urchin Paracentrotus lividus (Lamarck, 1816) was experimentally studied. Taken into account that the sampled population of E. verrucosa was infected with the parasitic barnacle Sacculina eriphiae Smith, 1906, four predator categories were established regarding crab sex and parasite presence: uninfected and infected males and females, respectively. Th ese four crab categories were fed on the six preys off ered, but prey remains suggest that the crab obtains the fl esh of each prey using diff erent methods of att ack. Irrespective of the prey species, uninfected females consistently presented lower percentages of crab feeding and total consumption. On average, it was found that a signifi cantly higher percentage of crabs feed on M. galloprovincialis, P. depressa and Ph. lineatus than on the other three prey species (chi-squared test, p < 0.05). In terms of mean eaten biomass, the preys most eaten were P. lividus and P. depressa and the least eaten was C. erythropus (ANOVA test, p < 0.05). For crabs feeding on M. galloprovincialis and Ph. lineatus there was a significant positive correlation (p < 0.05) between the predator size and prey size, as well as between the predator size and total prey consumption. According to these results, potential effects of this top predator on intertidal communities are also discussed.
