1. Ocular tentacle malformation in Deroceras reticulatum (Mollusca: Gastropoda: Agriolimacidae)
Abstract Malformations in animals have long been known. In gastropod, natural and induced malformations are mentioned in different systems and in ocular tentacles, mainly linked to cases of parasitism and exposure to pollutants (molluscicides and chemicals). In this study we present a new malformation not documented in the ocular tentacles of slug Deroceras

2. New record of the invasive snail Melanoides tuberculata (Gastropoda, Thiaridae) - Ceará State, Brazil
Resumo Melanoides tuberculata é um gastrópode de água doce nativo da África e da Ásia e atualmente apresenta-se distribuído mundialmente. O primeiro registro de Melanoides tuberculata na América do Sul ocorreu no Brasil, na cidade de Santos, estado de São Paulo, em 1967. Portanto, o objetivo do presente estudo é relatar a ocorrência de Melanoides t

3. Morphometric analysis of Littoraria angulifera (Caenogastropoda) in estuarine regions of northeastern Brazil
Resumo O gastrópode Littoraria angulifera (Littorinidae) é um molusco exclusivamente estuarino com distribuição anfiatlântica neotropical. Estudos recentes indicam um possível uso dessa espécie como bioindicadora. No presente estudo teve-se por objetivos analisar a altura da concha, assim como realizar uma análise morfométrica do aparato reprodutor

4. Effect of stock density of cultured Amazon Apple Snail Pomacea dolioides (Gastropoda: Ampullariidae) in Brazil
ABSTRACT This study evaluated the biomass gain, specific growth rate, absolute weight gain, and survival rate of the gastropod Pomacea dolioides cultivated in different stocking densities. To perform the experiment, samples were collected in March and June 2015. A total of 40 adult specimens were collected in the Jauary neighborhood (03°08′19.9"S, 58°27�

6. The exotic jumping snail Ovachlamys fulgens (Gude, 1900) (Gastropoda: Helicarionidae) in urban areas of the Upper-Paraná Atlantic Forest
ABSTRACT The exotic land gastropod Ovachlamys fulgens (Gude, 1900), aka the jumping snail, was registered in Eldorado city, Misiones province, constituting the first documented record of that species in Argentina-and for all of South America as well. Identities of the individuals were confirmed through morphological examination, and by a DNA sequencing of th

7. Shell occupation by the land hermit crab Coenobita violascens (Anomura, Coenobitidae) from Phuket Island, Thailand
Abstract Shell occupation by the land hermit crab Coenobita violascens Heller, 1862 was investigated from January 2011 to March 2012 on Phuket Island in the Andaman Coast of Thailand. The samples of C. violascens were collected monthly using multiple quadrat sampling. Twenty shell species from 11 families were found occupying by C. violascens, which were mai

8. Experimental predatory behavior of the stone crab Eriphia verrucosa (Forskål, 1775) (Decapoda, Brachyura, Eriphiidae)
Abstract Predatory behavior of the crab Eriphia verrucosa (Forskål, 1775) on the oyster Magallana angulata (Lamarck, 1819), the mussel Mytilus galloprovincialis Lamarck, 1819, the limpet Patella depressa Pennant, 1777, the hermit crab Clibanarius erythropus (Latreille, 1818), the gastropod Phorcus lineatus (da Costa, 1778) and the sea urchin Paracentrotus l

9. Predatory behavior of the paguroid Dardanus venosus (H. Milne-Edwards, 1848) (Anomura: Diogenidae) on the snail Aurantilaria aurantiaca (Lamarck, 1816) (Gastropoda: Fasciolariidae)
Abstract Paguroids are usually detritivorous organisms and the occurrence of predation on mollusks is very unusual. This contribution reports the occurrence of a predatory behavior of the paguroid Dardanus venosus (H. Milne Edwards, 1848) on the snail Aurantilaria aurantiaca (Lamarck, 1816). Single specimen of paguroid was found attacking the snail in a sea

10. An integrative approach-using field and laboratory data to characterize shell utilization and selection pattern by the hermit crab Pagurus criniticornis (Paguridae) from Anchieta Island, Brazil
Abstract The aim of this study was to characterize the pattern of gastropod shell occupation in the field and selection of shell size and type under laboratory conditions by the hermit crab Pagurus criniticornis (Dana, 1852), inhabiting the infralittoral area of Anchieta Island, São Paulo, Brazil. Hermit crabs were obtained monthly during 1999 by SCUBA divi

11. Habitat heterogeneity in the assemblages and shell use by the most abundant hermit crabs (Anomura: Diogenidae and Paguridae): does the occupied shell species differ according to gender and species?
Abstract The goal of this study was to identify patterns of shell occupation by different species of hermit crabs from the southern Brazilian coast. In total, 644 individuals were collected, represented by six hermit species. Isocheles sawayai Forest & Saint Laurent, 1968 showed the highest abundance, with 575 individuals, followed by Loxopagurus loxochelis

12. Population dynamics of Megalobulimus paranaguensis (Gastropoda: Pulmonata) in the southeast coast of Brazil
ABSTRACT. The population dynamics of Megalobulimus paranaguensis (Pilsbry & Ihering, 1900), a large and long-lived land gastropod from Brazil's Southeast (Atlantic Forest) was studied between 2006 and 2009, at an urban park in the city of Santos, state of São Paulo. The study included biometry, weighing, and marking and recapture of adult individuals. The v
