Pagurus longicarpus

Fig. 15.4 Frequency distributions of carapace length/shell weight ratios for Pagurus longicarpus attracted to Ilyanassa obsoleta (I) or to crushed conspecifics (P). Low ratios indicate relatively large shells for crab size. Modified after Rittschof et al. (1992)...

Fig. 15.7 Association between the odor of a familiar conspecific and one of three attributes (rank, body size, and shell quality) in Pagurus longicarpus (after Gherardi et al. 2005). The authors observed the response of a test crab to a well-fitting empty shell in the presence of seawater conditioned by the odor of two familiar conspecifics, analyzed separately for 5 min for each odor in random order. Three series of experiments were conducted same body size and same shell quality (1), different body size and same shell quality (2), and same body size and different shell quality (3). The better crab (and the worse crab) was the dominant (and subordinate) crab in (1),...
