Meireles Biología Crustacea Paguridae Pagurus exilis shell occupation southwestern Atlantic Shell preferences, as shown by laboratory choice experiments, are important determinants of shellutilization under natural conditions. Size and shell species preferences of the hermit crab Pagurus exilis weredetermined and compared for the most occupied shell types (Olivancillaria urceus, Natica isabelleana andBuccinanops gradatum) in the Caraguatatuba region, Brazil, and for the two most occupied species (B. gradatumand N. isabelleana) in Mar del Plata, Argentina. All experiments were conducted under laboratory conditions,using glass aquaria where the hermit crabs were placed naked with a large number of shells of appropriate sizes.After 36 h the crabs and chosen shells were measured. The relationship between preferred shell type, shell sizeand shell volume was determined by regression analysis. Pagurus exilis showed significant choices amongst shelltypes. Specimens from Argentina preferred N. isabelleana and those from Brazil chose B. gradatum > N. isabelleana> O. urceus. Preferences were characterized by shell weight and internal volume. The present data lead usto conclude that shell selection by hermit crabs involves individual preferences related to the shell features thatbest provide protection and survival. Rev. Biol.
