Ser. / Reproduction of the Continuously Breeding Tropical Hermit Crab Clibanarius clibanarius Sudha Varadarajan* and T. Subramoniam Department of Zoology, University of Madras, Madras 600005,India ABSTRACT: On the Indian east coast, the hermit crab Clibanarius clibanarius breeds continuously with peak activity from September to January, corresponding to the onset of the retreating monsoon. Individuals within the population breed asynchronously and vary widely in their carapace lengths. probably because of steady, year-round recruitment. Our data on reproduction emphasize the flexible use of an apparently stable, tropical environment by these crabs. INTRODUCTION 18 m. In January and February, 1976 and January, 1977 all crabs were scarce and few could be collected. In tropical marine waters, where sea temperatures Females, smaller in size than males, often occupied fluctuate little seasonally, many invertebrates are smaller gastropod shells of different species of Murex, known to reproduce throughout the year (Giese and Bursa, Babylonia or Turitella. After removal from the Pearse, 1974). In Indian waters a major factor that shell, the length from the tip of the rostrum to the influences intertidal as well as offshore forms is the posterior indentation on the mid-dorsal line of the monsoon rain that differs in time and intensity on the cephalothorax was taken as carapace length. The soft east and west coasts (Panikkar and Jayaraman, 1966). abdomen was opened, the ovaries were separated from Semiannual breeding patterns have been reported for the hepatic tissue and gonad-indexes and hepatic a number of species on the east coast of India (Giese indexes (Giese, 1967) and egg mass indexes (Sub- and Pearse, 1974), where little rain falls during the ramoniam, 1979) were calculated' '.

PROVENZANO, Jr. Institute of Marine Science,University of Miami, Florida, U.S.A. INTRODUCTION As part of a survey of the marine fauna and flora of the recently established U. S. Virgin Islands National Park at St. John, a series of collections have been made by Marine Laboratory personnel. Among the Crustacea taken were a number of new records for the Virgin Islands, including three species not referable to any yet named. The present report deals with the hermit crabs of the families Diogenidae and Paguridae; these families corresponding to those of MacDonald, Pike & Williamson ( 1 9 5 7 ) . Synonymies are restricted to the original description and one or more references usually containing more complete information. Size of specimens where given refers to carapace length. The station numbers refer to records kept by Herman Kumpf while at St. John; the field data being on file in the Marine Laboratory Museum. Unless otherwise noted, the general locality for material examined is St. John. Holotypes are deposited in the U. S. National Museum, while most of the remaining material is deposited in the University of Miami Marine Laboratory Museum (UMML). The writer is indebted to Dr. Marvin L. Wass of the Virginia Fisheries Labora- tory for examining the three new species and for comments incorporated in the manuscript. He would also like to thank Dr. John Randall and his co-workers who made special efforts to collect hermit crabs during their general field studies.

  • 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.

Picardal Palawan, Philippines College of Fisheries and Aquatic Sciences, Western Philippines University Rafael M. Picardal and Roger G. Dolorosa Roger G. Dolorosa Abstract College of Fisheries and Aquatic Sciences, Western Philippines With the rising pressure of urbanization to biodiversity, this study aimed to obtain baseline information University on species richness of gastropods and bivalves in two protected bays (Turtle and Binunsalian) in Puerto Princesa City, Philippines before the establishment of the proposed mega resort facilities. A total of 108 species were recorded, (19 bivalves and 89 gastropods). The list includes two rare miters, seven recently described species and first record of Timoclea imbricata (Veneridae) in Palawan. Threatened species were not encountered during the survey suggesting that both bays had been overfished. Turtle Bay had very low visibility, low coral cover, substantial signs of ecosystem disturbances and shift from coral to algal communities. Although Binunsalian Bay had clearer waters and relatively high coral cover, associated fish and macrobenthic invertebrates were of low or no commercial values. Upon the establishment and operations of the resort facilities, follow-up species inventories and habitat assessment are suggested to evaluate the importance of private resorts in biodiversity restoration. Keywords: Binunsalian Bay, bivalves, gastropods, Palawan, species inventory, Turtle Bay 1. Introduction Gastropods and bivalves are among the most fascinating groups of molluscs that for centuries have attracted hobbyists, businessmen, ecologists and scientists among others from around the globe.

Vermeij; e-mail: [email protected] Downloaded from (Received 5 September 2013; accepted 10 February 2014) ABSTRACT The shells of many marine gastropods have ventrally directed serrations (serial projections) at the edge http://mollus.oxfordjournals.org/ of the adult outer lip. These poorly studied projections arise as extensions either of external spiral cords or of interspaces between cords. This paper describes taxonomic, phylogenetic, architectural and func- tional aspects of serrations. Cord-associated serrations occur in cerithiids, strombids, the personid Distorsio anus, ocenebrine muricids and some cancellariids. Interspace-associated serrations are phylo- genetically much more widespread, and occur in at least 16 family-level groups. The nature of serration may be taxonomically informative in some fissurellids, littorinids, strombids and costellariids, among other groups. Serrated outer lips occur only in gastropods in which the apex points more backward than upward, but the presence of serrations is not a necessary byproduct of the formation of spiral sculp- tural elements.

ABSTRACT: The key deals with the Decapoda, Anomura of the northern Arabian Sea, belonging to 3 superfamilies, 10 families, 32 genera and 104 species. With few exceptions, each species is accompanied by illustrations of taxonomic importance; its first reporter is referenced, supplemented by a subsequent record from the area. Necessary schematic diagrams explaining terminologies are also included. KEY WORDS: Malacostraca, Decapoda, Anomura, Arabian Sea - key. INTRODUCTION The Infraorder Anomura is well represented in Northern Arabian Sea (Paldstan) (see Tirmizi and Kazmi, 1993). Some important investigations and documentations on the diversity of anomurans belonging to families Hippidae, Albuneidae, Lithodidae, Coenobitidae, Paguridae, Parapaguridae, Diogenidae, Porcellanidae, Chirostylidae and Galatheidae are as follows: Alcock, 1905; Henderson, 1893; Miyake, 1953, 1978; Tirmizi, 1964, 1966; Lewinsohn, 1969; Mustaquim, 1972; Haig, 1966, 1974; Tirmizi and Siddiqui, 1981, 1982; Tirmizi, et al., 1982, 1989; Hogarth, 1988; Tirmizi and Javed, 1993; and Siddiqui and Kazmi, 2003, however these informations are scattered and fragmentary. In 1983 McLaughlin suppressed the old superfamily Coenobitoidea and combined it with the superfamily Paguroidea and placed all hermit crab families under the superfamily Paguroidea.

Running head: Queensland pronocephaloid cercariae. Author for correspondence: D.C. Huston, Email: [email protected]. 1 Abstract The superfamily Pronocephaloidea Looss, 1899 comprises digeneans occurring in the gut and respiratory organs of fishes, turtles, marine iguanas, birds and mammals. Although many life cycles are known for species of the Notocotylidae Lühe, 1909 maturing in birds and mammals, relatively few are known for the remaining pronocephaloid lineages. We report the cercariae of five pronocephaloid species from marine gastropods of the Queensland coast, Australia. From Lizard Island, northern Great Barrier Reef, we report three cercariae, two from Rhinoclavis vertagus (Cerithiidae) and one from Nassarius coronatus (Nassariidae). From Moreton Bay, southern Queensland, an additional two cercariae are reported from two genotypes of the gastropod worm shell Thylacodes sp. (Vermetidae). Phylogenetic analysis using 28S rRNA gene sequences shows all five species are nested within the Pronocephaloidea, but not matching or particularly close to any previously sequenced taxon. In combination, phylogenetic and ecological evidence suggests that most of these species will prove to be pronocephalids parasitic in marine turtles.

Department of Biology Email: [email protected] , [email protected] , [email protected] , [email protected] Introduction Results Discussion Predation is one of the top concerns for organisms in a marine This research was an extremely productive sampling of environment. 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).
