Fighting for shells: how private information about resource value changes hermit crab pre-fight displays and escalated fight behaviour.
Pre-fight displays typically provide honest, but sometimes dishonest, information about resource holding potential and may be influenced by assessment of resource value and hence motivation to acquire the resource. These assessments of potential costs and benefits are also predicted to influence escalated fight behaviour. This is examined in shell exchange contests of hermit crabs in which we e...
متن کاملDo I stand out or blend in? Conspicuousness awareness and consistent behavioural differences in hermit crabs.
Animals titrate their behaviour against the level of risk and an individual's conspicuousness should influence decisions such as when to flee and for how long to hide. Conspicuousness will vary with variation in substrate colour. Since hermit crabs frequently change the shells they occupy, shell colour will also influence conspicuousness and to be aware of their conspicuousness would require in...
متن کاملLow richness of hermit crabs community (Crustacea: Decapoda: Paguroidea) and high dominance of Clibanarius signatus in the intertidal zones of Larak Island, Persian Gulf, Iran
Abstract Hermit crabs community in the intertidal zones of Larak Island were investigated through a seasonal sampling at five stations using random quadrate sampling method. Overall, seven species were identified and Clibanarius signatus was the dominant species, which showed high dominance over other species. Using Bray-Curtis cluster analysis for comparing seasonal abundance showed that exce...
متن کاملIndividual quality and personality: bolder males are less fecund in the hermit crab Pagurus bernhardus.
One explanation for animal personality is that different behavioural types derive from different life-history strategies. Highly productive individuals, with high growth rates and high fecundity, are assumed to live life at a fast pace showing high levels of boldness and risk taking, compared with less productive individuals. Here, we investigate among-individual differences in mean boldness (t...
متن کاملEffects of shell fit on the biology of the hermit crab Pagurus longicarpus (Say)
Most hermit crabs have a specialized lifestyle that requires them to occupy gastropod shells. The size of shells that hermit crabs inhabit relative to their body size affects their growth, survival and fecundity. In this study, the effects of shell fit on individual growth rate, risk of predation, feeding rate, and activity level were examined in the laboratory for hermit crabs Pagurus longicar...
