“…The main difference between P. bernhardus and P. prideaux in their use of shells and associated organisms is that P. bernardus commonly inhabit intact gastropod shells into which the crab can completely withdraw, preferring "hard-walled" whelks that, when alive, easily survive dredge and beam trawl impact. Therefore, larger P.bernhardus rely mostly on whelk shells throughout their species range (Lancaster, 1988a,b;Fernandez-Leborans and Gabilondo, 2006;Balazy et al, 2015) as well as the shells of other buccinid species when available (Peura et al, 2013). However, in the absence of buccinids the larger hermit crabs will use alternative resources.…”

“…The same sex ratio was noted in this species in Hakodate Bay (Wada & Mima, 2003). The females of many intertidal hermit crabs are known to be smaller than the males (Lancaster, 1990; Turra & Leite, 2000; Mishima & Henmi, 2008; Balazy et al , 2015). Reproduction is an energy-consuming process, limiting the growth of ovigerous females.…”

The population and reproductive characteristics of the hermit crab Pagurus proximus Komai, 2000 have been examined in the northern part of the species range (Vostok Bay, Peter the Great Bay, Sea of Japan). The average population density was 4–5 ind m−2 in winter and spring, 10 ind m−2 in summer and autumn; the biomass was 7–9 and 18–19 g m−2, respectively. Hermit crabs were found at a depth of 0 to 12 m but were most numerous at about 3 m depth with an average population density of up to 26 ± 7 ind m−2. The shield length of males varied from 1.3 to 7.8 mm and females from 1.2 to 6.7 mm. The male to female ratio was close to 1 but varied with size and season. Females attained sexual maturity at a shield length of more than 1.3 mm. Ovigerous females were found from December to August. The proportion of ovigerous females increased from 7% in December to 93% in late April; however, the embryos in clutches remained at early developmental stage until May. The mass release of larvae was observed at the beginning of June. A subsequent spawning probably took place in July. The main factors contributing to the high abundance of P. proximus in the investigated area are the presence of the embryonic diapause synchronizing the release of larvae at the most favourable time for their development, high fecundity, the presence of at least two egg clutches during the reproductive season, and total absence of parasites.

This study explores the abundance, diversity and assemblage structure of epifauna on the shells used by two hermit crab species (Pagurus bernhardus and P. pubescens) in the Arctic (Svalbard and Northern Norway) and investigates the biotic and physical drivers of such patterns. Contrary to our expectations, we found that location (which reflects the variability in environmental conditions and the local species pool of potential colonizers) is a key determinant not only in the cold, ice-scoured, glacierdominated Arctic shallows of Svalbard but also in boreal Norwegian fjords, where other factors were hypothesized to be more important. Depending on region, shell area and identity were of lesser magnitude, with larger and more irregular shells containing more diverse assemblages. Crab host species also played a role (P. pubescens-inhabited shells supported larger number of individuals and higher diversity than those of P. bernhardus) but this effect might be species or region specific. In this study, no effect of crab gender could be detected. The study indicated that epifaunal assemblages of hermit crab shells are influenced by complex set of factors that interact together to different degree at various locations.
