| Beschreibung: | Postplanktonic stages of Petrolisthes armatus are recorded as commensals of the limpet Crucibulum (C.) spinosum. Eigthy eigth limpets (18.8%) harbored one megalopa or one juvenile of this porcellanid. The monthly prevalence in aproximately 157 limpets collected from August to October was 18.47%, 28.02% and 9.74% respectively. This allowed us to establish one period and a half of recruitment for this crab in the upper Gulf of California. The gut contents of both species are quite different and we inferred that the commensalistic relationship is fur shelter. This diminishes the crab's vulnerability to predation at high-tide, and permits escape from desiccation at low-tide. |
