2. Natural diet of Ocypode quadrata (Fabricius, 1787) (Crustacea, Decapoda, Brachyura) from the Northern Coast of São Paulo, Brazil
Abstract Decapod crustaceans have a wide variety of feeding habits, alternating among herbivory, predation, saprophagy, and filtration. The occupation of various trophic positions in the food web is a key feature in the evolution of the group. Thus, we analyzed the natural diet of the crab Ocypode quadrata (Fabricius, 1787), commonly known as the ghost crab

3. Umalia trirufomaculata (Davie and Short, 1989) in India, with a note on the taxonomy of U. misakiensis (Sakai, 1937) (Decapoda: Brachyura: Raninidae)
Abstract The rare raninid crab Umalia trirufomaculata (Davie and Short, 1989) is recorded from India for the first time. It is redescribed and compared at length with the related but poorly known U. misakiensis (Sakai, 1937) on the basis of a good series of specimens from the Philippines. Some of the supposed differences which have been documented between th

4. First record of the genus Eumunida Smith, 1883 (Crustacea, Decapoda, Eumunididae) from the southwestern Atlantic, with the description of a new species
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 th

5. First confirmed record of the sesarmid crab, Parasesarma bengalense (Davie, 2003) (Decapoda: Brachyura) in Indian waters
ABSTRACT The mangrove crab, Parasesarma bengalense (Davie, 2003), was previously reported in an ecological study from the Coringa Wildlife Sanctuary of Andhra Pradesh on the east coast of India. No specimen, however, is readily available to confirm the identity of P. bengalense from the Coringa Wildlife Sanctuary. The present study confirms the presence of P

6. Morphological sexual maturity of the freshwater anomuran crab Aegla parana (Crustacea, Decapoda, Aeglidae) from Negro River Sub-basin, Upper Iguaçu Basin, southern Brazil
RESUMO O comprimento da carapaça (CL) no início da maturidade sexual morfológica (MSM) em Aegla paranaSchmitt, 1942foi estimado em uma população que ocorre na Sub-bacia do Rio Negro, Bacia do Alto Iguaçu, sul do Brasil. Os animais foram capturados com rede Surber e com armadilhas iscadas no Rio Negro e no seu afluente Rio Totó, em dezembro/2017, junho

7. Grooming behaviors and fouling of the spider crab Libinia dubia (Decapoda: Epialtidae)
Abstract Body fouling has been reduced by grooming behaviors. In decapods, grooming has been focused on gills, sensory structures, and jointed appendages. In this study, grooming behaviors of the spider crab, Libinia dubia H. Milne-Edwards, 1834, were examined; this brachyuran crab decorates and camouflages body regions by attaching materials onto hooked set

8. Intraspecific food resource partitioning in Brazilian silverside Atherinella brasiliensis (Atheriniformes: Atherinopsidae) in a tropical estuary, Brazil
RESUMO Nós investigamos a partição intraespecífica de recursos alimentares do peixe-rei Atherinella brasiliensis em um estuário tropical. Um total de 1.099 estômagos foi analisado, e a dieta foi constituída principalmente de Gastropoda, Larva de Ceratopogonidae, Larva de Decapoda, Calanoida, Cyclopoida, Hymenoptera e Brachyura. A análise de ordenaç�

9. Ovarian development and spawning of Macrobrachium amazonicum (Crustacea, Decapoda)
RESUMO Das espécies nativas de camarões da América do Sul, Macrobrachium amazonicum (Heller, 1862) é a mais importante para fins de aquicultura, possuindo elevado valor comercial. Devido à sua importância, este estudo objetivou avaliar a plasticidade fenotípica de fêmeas da espécie em relação ao desenvolvimento gonadal, e determinar o tipo de deso

10. Microhabitat preferences of the freshwater prawn Macrobrachium jelskii (Decapoda: Palaemonidae)
RESUMO Nós analisamos as preferências de micro-habitat de machos e fêmeas de Macrobrachium jelskii (Miers, 1877) em um açude urbano em Cruz das Almas, Bahia, Brasil. As amostras foram coletadas mensalmente, de março de 2015 a fevereiro de 2016, com o auxílio de uma peneira em três diferentes micro-habitats. Cada micro-habitat teve predomínio de uma e

12. Sexual and reproductive traits of the pearl oyster shrimp Pontonia margarita (Decapoda: Palemonidae), symbiotically inhabiting the mantle cavity of the rugose pen shell Pinna rugosa (Bivalvia: Pinnidae)
ABSTRACT Symbiosis between decapods and mollusks provides a unique opportunity to examine some of the evolutionary strategies employed by marine invertebrates. We describe the sexual and reproductive traits of the pearl oyster shrimp, Pontonia margarita Verril, 1869, found symbiotically inhabiting the mantle cavity of the rugose pen shell, Pinna rugosa Sower
