“…The biological aspects of hermit crabs are mostly influenced by the selection of gastropod shell (Bertness 1981) that does not occur by chance. Different factors play a vital role in the selection: shell availability, shell size, and shell species (Reese 1962;Rodrigues et al 2000;Mantelatto and Dominciano 2002;Mantelatto and Meireles 2004;Trivedi et al 2013;Trivedi and Vachhrajani 2013a). Different shell types and their morphological attributes provide various advantages to hermit crab species: a heavy and large shell provides protection against predators and also provides space for egg incubation but, on the other hand, it also affects locomotion and reduces reproductive success (Bertness 1981;Ohmori et al 1995;Wada et al 1997;Arguelles et al 2009).…”

This study focuses on evaluating the pattern of shell utilization by the hermit crab Clibanarius zebra collected from the intertidal zone of four different sites along the Saurashtra coast, Gujarat, India. Specimens were collected monthly from March 2012 to August 2013 during low tide; hermit crab weight (HW) and their shield length (SL) were measured. Gastropod shells were identified and different morphological variables were recorded [dry weight (DW), shell length (SHL), shell aperture length, and shell aperture width]. A total of 804 hermit crabs occupying 23 gastropod species were collected. Cerithium scabridum (41.8%) was the shell most occupied by the crabs followed by Turbo intercostalis (10.6%), Astrea stellata (7.8%), Lunella coronata (6.6%), and Chicoreus brunneus (5.6%). Significant difference was obtained in the percentage of shell occupation between sexes. Regression analysis showed a high correlation between the different morphological variables of hermit crabs and gastropod shells; the highest values of correlation were obtained between HW and DW.The high values of correlation coefficient and regression models between the different morphological variables of hermit crabs and gastropod shells suggest that shell architecture has a huge impact on shell utilization pattern of C. zebra.

Individuals of the terrestrial hermit crab Coenobita clypeatus Fabricius, 1787 use different gastropod shells for shelter during their life span. Availability of shells affects population traits, including density and size structure, influencing their fitness and survival. Locality and human presence can induce variation in the diversity and size of gastropod shells, influencing available shells for hermit crabs. We assessed how the diversity, size, and abundance of the occupied species of gastropod shells affect the density and demography of C. clypeatus in two marine protected areas (MPA) with different recreational use in Puerto Rico, Manatí (high) and Mona Island (low). We also evaluated the relationship between three shell traits (length, width, and aperture length) and the length of the crab chela as a size proxy. We did not find differences in the sex ratio. The density and median chela sizes were higher in crabs from Manatí. In Mona, however, they reached larger sizes. The diversity of occupied shell species was higher in Manatí than in Mona. Dimensions of occupied shells differed between genera and between study sites, and they scaled positively with hermit crab size. Differences in shells diversity, sizes, and abundance between MPAs might cause differences in density and demography of C. clypeatus. We only found large shells of Cittarium pica (Linnaeus, 1758), the only species occupied by larger individuals, occupied by hermit crabs in Mona. The low abundance of C. pica shells in Manatí might have affected the size of hermit crabs in this locality. Our in situ findings suggest that hermit crabs need larger shells to reach larger sizes as previously shown, and that location and the degree of human intervention might influence the availability of gastropod shells. Our study is the first attempt to characterize the demography and gastropod shells used by hermit crabs in Puerto Rico.
