Part I. an Annotated Checklist of Extant Brachyuran Crabs of the World
THE RAFFLES BULLETIN OF ZOOLOGY 2008 17: 1–286 Date of Publication: 31 Jan.2008 © National University of Singapore SYSTEMA BRACHYURORUM: PART I.

F. Davie Queensland Museum, PO Box 3300, South Brisbane, Queensland, Australia Email: [email protected] ABSTRACT. – An annotated checklist of the extant brachyuran crabs of the world is presented for the first time. Over 10,500 names are treated including 6,793 valid species and subspecies (with 1,907 primary synonyms), 1,271 genera and subgenera (with 393 primary synonyms), 93 families and 38 superfamilies. Nomenclatural and taxonomic problems are reviewed in detail, and many resolved. Detailed notes and references are provided where necessary. The constitution of a large number of families and superfamilies is discussed in detail, with the positions of some taxa rearranged in an attempt to form a stable base for future taxonomic studies. This is the first time the nomenclature of any large group of decapod crustaceans has been examined in such detail.

Around 1,500 living species of starfish occur on the seabed in all the world's oceans, from the tropics to subzero polar waters. They are found from the intertidal zone down to abyssal depths, 6,000m below the surface. Starfish typically have a central disc and five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. -

Reduced Mobility Is Associated with Compensatory Feeding and Increased Diet Breadth of Marine Crabs
MARINE ECOLOGY PROGRESS SERIES Published November 3 Mar Ecol Prog Ser Reduced mobility is associated with compensatory feeding and increased diet breadth of marine crabs John J. Stachowicz*,Mark Hay8* University of North Carolina at Chapel Hill, Institute of Marine Sciences. Morehead City, North Carolina 28557. USA ABSTRACT: Direct effects of predation have been widely recognized as important in affecting prey population dynamics and evolution. However, less attention has been devoted to the consequences of indirect effects of predators on prey behavior. For example, to avoid predation many animals restrict their activities to physical refugia and adopt low-mobility Mestyles, yet the consequences of these anti- predator behaviors for foraging and diet selection are relatively unknown. In this study we examine the relationships between mobility, feeding preferences, and compensatory feeding for 3 species of marine decapod crabs feeding on seaweeds in North Carolina, USA. Low mobility and high site fidellty of crabs were associated with a broad, non-selective diet and compensatory feeding. The majid Mithrax forceps exhibited the lowest mobility, highest site fidelity, and least selective diet of the 3 species, whereas another majid Libinia dubia was intermehate in both rnobllity and selectivity, and the xanthid Panopeus herbstii had the greatest mobility and narrowest diet. Of these 3 crabs, only M. forceps com- pensated for low food quality by increasing consumption rates in single food-species feeding assays. This may be because M. forceps is resistant to (or tolerant of) seaweed chemical defenses, while other crab species are not. The ability to consume, and presumably subsist on, a wide variety of potential foods including those defended from more mobile consumers may facilitate a low-mobllity lifestyle, allowing the crab to minimize movement and reduce exposure to predators. -

Asterozoans are free living, star-shaped echinoderms which are important components of benthic marine faunas worldwide. Their fossil record is, however, poor and fragmentary, probably due to dissarticulation of ossicles. In particular, fossil asteroids are infrequent in South America. A new species of starfish is reported from the early Valanginian of the Mulichinco Formation, Neuquén Basin, in the context of a shallow-water, storm-dominated shoreface environment. The specimen belongs to the Astropectinidae, and was assigned to a new species within the genus Tethyaster Sladen, T. antares sp. nov., characterized by a R:r ratio of 2.43:1, rectangular marginals wider in the interbrachial angles, infero- marginals (28 pairs along a median arc) with slightly convex profile and flat spines (one per ossicle in the interbrachials and two per ossicle in the arms). -

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. -

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).
