DEVANEY,3 and BARRY ROTH 4 ABSTRACT: Anatomy and cnidae distinguish two species of deep-sea ac­ tinians that produce coiled, chitinous shells inhabited by hermit crabs of the genus Parapagurus. The actinian type species, Stylobates aeneus, first assigned to the Mollusca, occurs around Hawaii and Guam with P. dofleini.

CRAIG1* & DARRYL L. FELDER1 1Department of Biology and Laboratory for Crustacean Research, University of Louisiana at Lafayette, P.O. Box 42451, Lafayette, Louisiana, 70504–2451, [email protected]; https://orcid.org/0000-0001-7679-7712 *Corresponding author. [email protected]; https://orcid.org/0000-0002-3479-2654 Abstract Morphological characters, as presently applied to describe members of the Paguristes tortugae Schmitt, 1933 species complex, appear to be of limited value in inferring phylogenetic relationships within the genus, and may have similarly misinformed understanding of relationships between members of this complex and those presently assigned to the related genera Areopaguristes Rahayu & McLaughlin, 2010 and Pseudopaguristes McLaughlin, 2002. Previously undocumented observations of similarities and differences in color patterns among populations additionally suggest genetic divergences within some species, or alternatively seem to support phylogenetic groupings of some species. In the present study, a Maximum Likelihood (ML) phylogenetic analysis was undertaken based on the H3, 12S mtDNA, and 16S mtDNA sequences of 148 individuals, primarily representatives of paguroid species from the western Atlantic. This molecular analysis supported a polyphyletic Diogenidae Ortmann, 1892, although incomplete taxonomic sampling among the genera of Diogenidae limits the utility of this finding for resolving family level relationships.

Zool Stud 57:61. doi:10.6620/ZS.2018.57-61. Jibom Jung, Jongwoo Jung, and Won Kim (2018) A phylogenetic study was conducted to investigate whether distinct genetic groups are present within the East Asian Pagurus minutus. In this study, 167 individuals of P. minutus were collected along the coasts of South Korea, east coast of Honshu, west coast of Kyushu, Okinawa Islands of Japan, and Taiwan. The collection of P. minutus was divided into three groups based on the differences in cytochrome c oxidase subunit I (COI) sequences and morphological and color characters: Major Group (MAG), Minor Group (MIG), and Taiwan-Okinawa Group (TOG). MAG commonly inhabits the entire coast of South Korea (except for the northeast coast), east coast of Honshu, and west coast of Kyushu in Japan. MIG predominantly inhabits the northeast coast of South Korea, while a small proportion inhabits the west coast of South Korea and west coast of Kyushu in Japan.

La plupart de ces associations montrent un rapport hauteur/largeur allant de 1/1,8 à 1/1,2 ce qui est approximativement le rapport de la coquille du Gastéropode. La dominance établie n'est affectée, ni par la forme visuelle ni par le volume de l'association entière montrée par le gagnant ou le perdant, mais les animaux d'un statut social élevé (les plus gros), choisissent des types de défense plus légers (coquille + association, en relation avec leur propre poids) que les plus petits.

  • The Effect of Anemone Size and Hermit Crab Behavior on the Distribution of Calliactis Tricolor (Le Sueur) on Snail Shells
    Symbiosis, 10 (1991) 123-134 123 Balaban, Philadelphia/Rehovot The Effect of Anemone Size and Hermit Crab Behavior on the Distribution of Calliactis tricolor (Le Sueur) on Snail Shells WILLIAM R. BROOKS Florida Atlantic University, Department of Biological Sciences Boca Raton, FL, USA Tel. (407) 3673320, FAX (407) 3672749 Received March 16, 1990; Accepted September 2, 1990 Abstract The purpose of this study was to analyze the distribution of symbiotic sea anemones by size on snail shells of hermit crabs and to determine whether these patterns are the result of anemone or crab behavior. The distribution in the field of the anemone Calliactis tricolor on the shells of the hermit crab Dardanus venosus was recorded. Tests were also done in which crabs were given simultane• ous access to a large and small anemone. The crab's transfer behavior and posi• tions of transferred anemones on the shell were recorded. Analysis of field data showed little correlation between crab/shell size and the number of anemones, but anemones were nonrandomly distributed on the shells. Additionally, large anemones were found more commonly on top of the shell, while small anemones usually bordered the shell aperture. Choice tests showed crabs had preference for large anemones. Small anemones were frequently eaten. There was also a significant difference in the transfer behavior of the crabs with the two size classes of anemones. The chelipeds and pereiopods were rarely turned beyond 45° of vertical when transferring small anemones, but were frequently parallel to the substratum when transferring large anemones. These postural changes resulted in large and small anemones being placed in similar patterns to field distributions.
