Abstract

For hermit crabs, a gastropod shell is an important resource that affects individual survival and reproduction. However, since shell resources are generally in short supply in the field, coexistence mechanisms are required to enable the occurrence of multiple hermit crab species in the same area. Here, we examined the shell utilization pattern of hermit crabs and gastropod distribution on the rocky shore at Kattoshi, Hakodate Bay, Japan where six hermit species coexist. Since more than 90% of them were Pagurus filholi and Pagurus middendorffii, we focused on the factors affecting the coexistence of these two abundant species in detail. The top five common gastropod species were Reticunassa spp. (Reticunassa fratercula or Reticunassa multigranosa), Littorina brevicula, Cantharidus japonicus, Lirularia iridescens, and Homalopoma sangarense. Although both P. filholi and P. middendorffii commonly used H. sangarense and Reticunassa spp., P. filholi used Ocenebra inornatus and P. middendorffii used Ca. japonicus more often. Additionally, the two hermit species differed the hermit–shell size relationship when they used Ca. japonicus. Interspecific variations in the shell utilization pattern may contribute to the coexistence of P. filholi and P. middendorffii in our study site.
