Abstract
The swimmerets (pleopods) of the abdomen of the hermit crab,Pagurus pollicarus, are found only on the left side of the abdomen. The muscles of the swimmeret of the 3rd segment are described; they are similar to each other in average sarcomere length, muscle fiber diameters, junction potential amplitudes and facilitation indices. In comparison with shrimp (Penaeus duorarum), lobster (Homarus americanus) and crayfish (Procambarus clarkii) swimmerets, those of the hermit crab appear morphologically simplified. Reflex activation of power and return stroke muscles differs from that described for the lobster, suggesting physiological as well as morphological plasticity in decapod swimmeret systems.
