| We evaluated the gastropod shell utilization pattern of the hermit crab Clibanarius vittatus (Bosc, 1802) at Pescadores Beach in São Vicente, State of São Paulo, Brazil. Specimens were collected monthly from May 2001 through April 2003, in the intertidal zone at low tide. The crabs were weighed and their carapace shield length measured. All gastropod shells were identified and had their shell biometric parameters (total length and aperture length) measured (mm) and weighed (g). A total of 2,344 hermit crabs (644 males, 1,594 females, 45 ovigerous females and 61 individuals in intersex), using 13 species of gastropod shells, were collected. Stramonita haemastoma (Linnaeus, 1767), Cymatium parthenopeum (Von Salis, 1793) and Achatina fulica (Bowdich, 1822)... |

| Shell selection by the hermit crab Paguristes tortugae Schmitt, 1933 from Anchieta Island (Brazil) was analyzed using the six most frequently occupied shell species in the field and taking into account the sexual condition of the individuals, the shell size and the shell species. The experiments were conducted under laboratory conditions and the shell species preference was estimated on the basis of the frequency that each species was chosen by the individuals. The preferred shell species and size were determined by regression analysis. The highest correlation coefficients were obtained for the relations between the hermit dimensions and shell dry weight. The ovigerous females preferred shells with larger internal volume: Leucozonia nassa (Gmelin, 1791)... |

| O efeito estimulante da spiperona e da naloxana sob a maturação ovariana foram avaliados em fêmeas de Aegla uruguayana Schmitt, 1942 e, para isto, tais neuroreguladores foram incorporados ao alimento e administrados a uma dose de 10-8 mol/animal a cada sessão de alimentação. Fêmeas adultas foram coletadas com puçá em um arroio próximo à cidade de Salto, Província de Buenos Aires, Argentina. Dez fêmeas foram sacrificadas, medidas, pesadas e os seus ovários foram retirados e pesados para a determinação do índice gonadossomático (IG). As demais fêmeas (30) foram divididas em três grupos experimentais - (a) controle: alimentadas com pellets controle composto por ração para peixe - 34% de proteína e 43% de proteína; (b) spiperona: alimentadas com pellets... |

| Macquarie Ridge is one of the southernmost seamount ridges, spanning 1600 kilometres from the southern tip of New Zealand to the Australia-Pacific-Antarctic triple junction halfway to Antarctica. Squat lobsters, superfamilies Chirostyloidea and Galatheoidea, are highly diverse at low and mid-latitudes, declining rapidly towards the poles; only 15 of the more than 1000 species have been recorded south of 50 degrees S. Prior to the present study, one species of squat lobster (Munidopsis pyrochela, Munidopsidae) was known from the Macquarie Ridge, but recent research voyages in 2003 and 2008 collected a further five species from both superfamilies and three families. Uroptychus tracey (Chirostylidae) is new to science. Uroptychus insignis (Henderson, 1885) is... |

| The deep-sea squat lobster, Munidopsis serricornis (Loven, 1852), originally described from the north-eastern Atlantic, has long been considered near cosmopolitan with numerous reports also from the western Pacific and northern Indian Ocean. These Indo-West Pacific records are reviewed along with new material from seamounts throughout the region. Munidopsis serricornis sensu stricto is restricted to the Atlantic Ocean. Six new species are described from the Indo-West Pacific: M alcocki sp. nov. from the central to western Indian Ocean; M atlantis sp. nov., from the Southwest Indian Ridge; M macphersoni sp. nov. from the Austral Islands, French Polynesia; M spiridonovi sp. nov. from the western Indian Ocean; M nias sp. nov. from southern Indonesia and the... |

| Twenty-two species of the genus Munidopsis from the Atlantic Ocean are studied. Five new species are described (M. anemia, M. exuta, M. hirtella, M. laurentae and M. truculenta), and diagnoses and illustrations of some relatively rare species (M. acuminata, M. bairdii, M. livida, M. parfaiti and M. thieli) are provided. None of the species discussed here is restricted to a particular habitat, including species collected from hydrothermal vent (M. acutispina, M. exuta) and cold seep areas (M. acutispina, M. geyeri, M. hirtella, M. livida, M. marionis). The new records of some species greatly extend the previously known distribution range of the species (i.e., M. abyssicola, M. aries, M. bairdii, M. geyeri, M. livida, M. parfaiti, M. thieli). Finally, some... |

| Carcinization, or the process of becoming a crab, has been, and continues to be, a focal point of anomuran evolutionary hypotheses. Traditional examples of carcinization in the Anomura are most celebrated among hermit crabs but certainly are not limited to this group. Carcinization, if it has occurred, has done so independently in all major anomuran taxa. In this critique, the traditional examples of carcinization in the Anomura are reviewed and more modern variations on the theme assessed. Potential pathways of carcinization are examined from perspectives of adult morphology in the Paguroidea, Galatheoidea, Hippoidea and Lomoidea, with emphasis on the Paguroidea. Specific attention is given to the theoretical transformation of a hermit crab-like body form... |

| Strata of latest Cretaceous (late Maastrichtian) and earliest Paleogene (early Paleocene) age in the (extended) type area of the Maastrichtian Stage are comparatively rich in decapod crustaceans. Particularly common are chelae of the callianassoid Mesostylus faujasi (Desmarest, 1822), followed by carapaces of various species of necrocarcinid and raninid, plus the ?longusorbiid Binkhorstia ubaghsii (van Binkhorst, 1857) and chelae of paguroids; other taxa are much rarer. Recently collected material, all stratigraphically well constrained, has enabled us to reinterpret, and reassign, a number of species. Specimens contained in old museum collections have proved indispensable in that respect. Undescribed taxa have also come to light; here a new dromioid,... |

| A phylogenetic analysis of selected anomuran, thalassinidean, and other decapod crustacean taxa, based on spermatozoal ultrastructural characters and spermatophore morphological characters, was performed and the following relationships of the taxa are elucidated from the trees produced. The Anomura are not a monophyletic assemblage, with the lomoid Lomis being exclusive of the remainder of the anomuran taxa, and the thalassinid Thalassina included in the anomuran clade. The synapomorphy joining the majority of the conventional anomuran taxa ( Lomis excluded) is the cytoplasmic origin of the microtubular arms. When the palinurid and thalassinoid representatives are separately designated as outgroups, the Astacidea and Brachyura jointly formed a sister group... |

| Abstract Eumunida pictaSmith, 1883, was considered for over a century an amphi-Atlantic species and the only representative of the genus in the Atlantic Ocean, until being split into three species: E. picta sensu stricto (from the northwestern Atlantic), E. bellade Saint Laurent & Macpherson, 1990 and E. squamiferade Saint Laurent & Macpherson, 1990 (from the northeastern and southeastern Atlantic, respectively). Eumunida is now expanded to include a new species, E. notialis, from off the Brazilian coast. Hence, this is the first record of Eumunida and Eumunididae from the southwestern Atlantic. The new species differs from all its Atlantic counterparts in having (1) four hepatic spines; (2) two carapace inframarginal spines; (3) the distal end of... |

| The present study analyzed the growth of males and females of the hermit crab Clibanarius vittatus (Bosc, 1802), at São Vicente, São Paulo, Brazil. Monthly collections were made from May/2001 through April/2003, at the Pescadores Beach in São Vicente. The 2,501 crabs caught were identified and sexed and the carapace shield length (CSL) was measured. For the seasonal growth study, the population was divided into 5mm size classes (CSL) and analyzed by the Bertalanffy method, with the aid of the program Fisat II. The mean sizes of the 703 males and 1,798 females were 8.94±1.80 and 6.61±1.13 mm, respectively. A seasonal growth pattern was observed, with males reaching an asymptotic size (14.92 mm) larger than that of females (13.85 mm). Males began the growth... |
