(With 33 Text-figures and 7 Tables) Introduction Descriptive accounts of larvae of a number of Diogenidae and Paguridae species from different geographic regions have been given -among others-, by MacDonald, Pike and Williamson, (1957); Pike and Williamson (1960); Proven zano (1963; 1968a ); Makarov (1967); Roberts (1970; 1973); Biffar and Proven zano (1972); Nyblade and McLaughlin (1975); Hong (1981), but our knowledge of larvae of species of both families from Japan is still deficient. The list of anomuran crabs inhabiting the coasts of Hokkaido, northern Japan includes approximately 15 species of hermit crabs (Igarashi, 1970; Miyake, 1982), for which only some reports have been published on their larval stages, so that the larvae of several of these species (especially those of the genus Paguristes and approximately the 50% of the Pagurus species) remain so far unknown. Kurata (1964) described the larvae of several Pagurus species from the coasts of Hokkaido.

ZOOBANK: http://zoobank.org/urn:lsid:zoobank.org:pub:C7D42A69-A8DF-4999- 90F1-C3A19CB0557D ABSTRACT A new behavior related to shell care was recently reported for the intertidal hermit crab Clibanarius erythropus (Latreille, 1818) in the Gulf of Cádiz (southwestern Europe). It also has been observed in other species of the diogenid genera Clibanarius Dana, 1952, and Calcinus Dana, 1951, however, it has not been described as an active behavior. In the present study, intertidal hermit crabs from different species and localities were sampled to assess if air-exposure is a shell cleaning behavior restricted to some species of intertidal hermit crabs or if it is a more generalized behavior among species inhabiting intertidal habitats. -
The Effects of Isolation on the Behavioral Interactions of Juvelnille Land Hermit Crabs (Coenobitidae) from the Motus of Mo’Orea, French Polynesia
ONE IS THE LONLIEST NUMBER: THE EFFECTS OF ISOLATION ON THE BEHAVIORAL INTERACTIONS OF JUVELNILLE LAND HERMIT CRABS (COENOBITIDAE) FROM THE MOTUS OF MO’OREA, FRENCH POLYNESIA *WITH AN APPENDIX SURVEYING THE HERMIT CRAB SPECIES PRESENT ON SELECT MO’OREAN MOTUS. VANESSA E. VAN ZERR Integrative Biology, University of California, Berkeley, California 94720 USA, [email protected] Abstract. Hermit crabs interact with each other in a variety of ways involving spatial use (aggregations, migrations), housing (shells), mating, recognition of conspecifics, and food. To test if isolation from conspecifics affects the behavioral interactions of hermit crabs, crabs of the species Coenobita rugosus (Milne‐Edwards 1837) of Mo’orea, French Polynesia were isolated from each other for two days, four days, six days, fifteen days, and twenty‐two days. They were kept in individual opaque containers with separate running seawater systems to prevent them from seeing or smelling each other. Afterwards, the hermit crabs were put into a tank two at a time and their behavior was recorded and compared to the behaviors of non‐isolated crabs. Behaviors looked at fell into two categories: 1) “social” interactions, meaning that the crabs reacted to each other’s presence, and 2) “nonsocial” interactions, meaning that the crabs either ignored each other’s presence or actively avoided behavioral interactions with other crabs. Results indicated that although “social” behavior showed a slight decreasing trend over time, it was not significant; however, the amount of “nonsocial” avoidance behavior seen increased significantly the longer crabs were isolated.

A Novel Interaction: the Thin Stripe Hermit Crab, Clibanarius
A NOVEL INTERACTION: THE THIN STRIPE HERMIT CRAB, CLIBANARIUS VITTATUS, KILLS THE FLORIDA CROWN CONCH, MELONGENA CORONA, FOR ITS SHELL by Jennifer Cutter A Thesis Submitted to the Faculty of Charles E. Schmidt College of Science In Partial Fulfillment of the Requirements for the Degree of Master of Science Florida Atlantic University Boca Raton, FL August 2017 Copyright by Jennifer Cutter 2017 ii ACKNOWLEDGEMENTS I would like to thank Florida Atlantic University, Harbor Branch Oceanographic Institute, and Dr. Donna Devlin for giving me the opportunity to conduct this fascinating study. I would also like to thank the other committee members (Dr. Vincent Encomio, Dr. Edward Proffitt, and Dr. William Brooks) for their help, advice, and guidance. This work was made possible through funding from the Indian River Lagoon Research Fellowship awarded by the Harbor Branch Foundation and a scholarship awarded by The Broward Shell Club. Additionally, I would like to thank Dr. Richard Turner for being willing to meet with me on several occasions to answer questions and share his vast knowledge. iv ABSTRACT Author: Jennifer Cutter Title: A Novel Interaction: The thin stripe hermit Crab, Clibanarius vittatus, kills the Florida crown conch, Melongena corona, for its shell Institution: Florida Atlantic University Thesis Advisor: Dr. Donna Devlin Degree: Master of Science Year: 2017 The hermit crab Clibanarius vittatus kills Melongena corona solely to acquire a better fitting shell. This finding is contrary to previous studies, which found that hermit crabs of other species cannot kill gastropods or, in most instances, remove freshly dead gastropods from their shells. This interaction cannot be classified as predation because Melongena tissue was never consumed. -
Hermit Crabs from the South China Sea (Crustacea: Decapoda: Anomura: Diogenidae, Paguridae, Parapaguridae)
THE RAFFLES BULLETIN OF ZOOLOGY 2000 Supplement No. 8: 377-404 © National University of Singapore HERMIT CRABS FROM THE SOUTH CHINA SEA (CRUSTACEA: DECAPODA: ANOMURA: DIOGENIDAE, PAGURIDAE, PARAPAGURIDAE) Dwi Listyo Rahayu Rand D Center for Oceanology, Indonesian Institute of Sciences (LIP/), Jt. Pasir Putih I, Ancol Timur, PO Box 4801 JKTF, Jakarta 11048, Indonesia ABSTRACT. - One hundred and two species of hermit crabs are recorded from the South China Sea. Information presented is from published references to the species. Most of the species are widely distributed in the Indo-West Pacific. INTRODUCTION Studies on hermit crabs of the South China Sea were done mostly according to country border and not to geographical border, such as hermit crab of Singapore and Malaysia (Nobili, 1900; 1903a, c; Lanchester, 1902; Rahayu, 1996), Vietnam (Fize & Serene, 1955; Forest, 1956c; 1958), Philippines (Estampador, 1937, 1959), Taiwan (Yu, 1987; Yu & Foo, 1990) and China (Wang, 1994). Some hermit crabs from this region are mentioned in the revision of one or more taxonomical groups, such as revision of the family Parapaguridae (de Saint Laurent, 1972; Lemaitre, 1996, 1997), genus Aniculus (Forest, 1984), genus Pagurixus (McLaughlin & Haig, 1984), genus Pylopaguropsis (McLaughlin & Haig, 1989), genus Pylopagurus and Tomopagurus (McLaughlin & Gunn, 1992) and genus Trizopagurus (Forest, 1995). One hundred and two species belonging to family Diogenidae, Paguridae and Parapaguridae are recorded from the South China Sea. The family Diogenidae is represented by eight genera (Aniculus, Calcinus, Ciliopagurus, Clibanarius, Dardanus, Diogenes, Paguristes and Strigopagurus), the family Paguridae is represented by eight genera (Australeremus, Ceratopagurus, Nematopagurus, Paguritta, Pagurixus, Pagurus, Pylopaguropsis and Spiropagurus) and the family Parapaguridae is represented by four genera (Bivalvopagurus, Oncopagurus, Paragiopagurus, and Sympagurus). -

The evolutionary adaptations and practices of many gastropod shells, as our average of over 18 shells per quadrat species are geared towards protection against threats that can was substantial. With this data, our hypotheses regarding hermit come from anywhere around them; the way each species expends crab shell size preference was supported, with both C. tricolor energy in forms of protection is called the optimal defense and other hermit crab species exhibiting smaller shell size than hypothesis. One example of this is shell selection by marine hermit gastropods. This supports previous research that suggested crabs. Hermit crabs are known to consider at least two factors when that hermit crabs allocate resources to defense rather than choosing their new shells: shell thickness and interior size (Ragagnin et al. 2016). While terrestrial hermit crabs favor airier growth. Additionally, we found that hermit crabs are indeed interiors with room to grow, marine hermit crabs in particular tend to selective on the basis of aperture type, with C. tricolor chose shells that are thicker and heavier because of their increased individuals preferentially selecting shells with a teardrop-shaped defense capacity, despite their limitations for growth (Alcaraz, aperture, and other hermit crabs preferentially selecting shells Chávez-Solís, & Kruesi, 2015). -

Box 5667 St. John's, Newfoundland, Canada AIC 5XI Abstract Two sympatrk species of Hermit Crab, Pagurus aeadianus and P. arcuatus, from the sublittoral near St. Chads, Newfoundland, have many similarities in their life history. These are expressed in their feeding, maturities of females (both species hatching eggs in early spring. extruding eggs in late autumn and carrying eggs through the winter), finding shells plentiful at small sizes but scarce at large sizes, and availability at a sublittoral station throughout the year. Differences seen were low rate of parasitization with Peltogaster paguri in P aeadianus: only one in almost five hundred specimens, while there were about 18% in P arcuatus; and in the former slightly higher fecundity, longer period of male maturity, somewhat larger size, and, as shown earlier, lower frequency in plankton from the area. Percent of ectocommensal protozoans on gills was low in P aeadianus but high in P areuatus, while those on setae of maxillule were high in both species.
