| This work describes the behavioral repertory of Trichodactylus panoplus von Martens, 1869, based on the animals' diel activity and the possible substrate preference under laboratory experiments. Three experimental replicates were carried out, each using six animals (three males and three females). There were four periods of observation a day, with a total of 864 observation sessions and 144 hours of experiments. A total of 15 behavioral acts divided into five categories were recorded: feeding, exploration of the environment, immobility, social interaction, and self-grooming. The obtained results suggest that T. panoplus has greater activity during the night (p < 0.05), yet without showing an activity peak. In addition, the acceptance of food does not... |

| The present study focused on the decapod fauna of the fluvial-estuarine environment of the Guajará Bay, in the Brazilian state of Pará, where specimens were collected monthly from six sites, from May 2006 to April 2007. A total of 6,793 specimens were captured, belonging to 11 species of crab and shrimp: eight palaemonids - Macrobrachium amazonicum (Heller, 1862), Macrobrachium surinamicum Holthuis, 1948, Macrobrachium carcinus (Linnaeus, 1758), Macrobrachium rosenbergii (De Man, 1879), Macrobrachium spp. 1-4 -, one portunid - Callinectes bocourti A. Milne-Edwards, 1879 -, and two trichodactylids - Sylviocarcinus devileii H. Milne-Edwards, 1853 and Sylviocarcinus pictus (Milne-Edwards, 1853). While no significant differences were found in the ecological... |

| Biological aspects of palemonids, collected from March, 91 to December, 95 in the Ratones Hidrographic Basin, Florianópolis, Santa Catarina, have been investigated. Individuals of different sizes of Macrobrachium acanthurus (Weigmann, 1836), Macrobrachium carcinus (Linnaeus, 1758), Macrobrachium olfersii (Weigmann, 1836), Macrobrachium potiuna (Müller, 1880), Palaemonetes argentinus Nobili, 1901 and Palaemon pandaliformis (Stimpson, 1871) were registered. These prawns, showed reproductive strategies, typical of the Palaemonidae (Rafinesque, 1815), associated to species particularities, and seem to adapt to different environmental conditions. |

| Foi estudada a biologia reprodutiva de Macrobrachium brasiliense (Decapoda: Palaemonidae) com base em 2604 indivíduos coletados entre outubro de 1994 e agosto de 1995, em dois igarapés de terra firme da estrada Iquitos-Nauta, Loreto (Amazônia peruana). A proporção sexual fêmea: macho foi de 1,7:1 sendo que as fêmeas foram um pouco mais abundantes que os machos durante todo o período de coleta. M. brasiliense apresentou dimorfismo sexual no comprimento cefalotorácico, sendo as fêmeas ligeiramente menores que os machos. A reprodução foi contínua, com o pico reprodutivo entre abril e julho. A fecundidade variou de 15 a 168 ovos por fêmea, observando-se uma relação significativa entre a fecundidade e o comprimento cefalotorácico e o peso. O volume do ovo não... |

| RESUMO Este estudo teve por objetivo caracterizar a diversidade carcinológica de dois manguezais (igarapés Buenos Aires e Tronco) da Baía de São Marcos, na costa amazônica maranhense, Brasil. Foram realizadas quatro coletas trimestrais entre setembro de 2011 a junho de 2012. Em cada coleta foram analisados três pontos por área (zona 1, zona 2 e zona 3), totalizando 24 amostras. O material biológico foi coletado por meio de arrastos com rede do tipo puçá, catação manual e técnica de braceamento. Paralelamente à coleta do material biológico, foram verificados a salinidade, temperatura e oxigênio dissolvido de cada área analisada. Para avaliar a similaridade de agrupamento entre as zonas dos manguezais foi aplicada a análise de cluster e consecutiva... |

| During the NNM/Maluku Expedition 1996, in the framework of the NNM Fauna Malesiana Marine Program, a shrimp belonging to the species Periclimenes imperator Bruce, 1967, was found on a nudibranch while diving at 20 m depth in Seri Bay, on the south coast of Ambon. Periclimens imperator has been recorded throughout the tropical Indo-West Pacific, from East Africa and the Red Sea to Hawaii, from nudibranch and holothurian hosts. The nudibranch was identified as Chromodorus magnifica (Quoy & Gaimard, 1832) (see Rudman, 1982: 216-219, figs. 17A, B, 18, 19). The association with Chromodorus magnifica is recorded here for the first time. |

| The Lagoa do Peixe ("Peixe's Lagoon") is located between Atlantic Ocean and Lagoa dos Patos and is 30 Km long and 0,5-2,0 Km wide (31º13'S, 50º55'W -31º26'S, 51º09'). For one year, the composition and distribution of Crustácea Decapoda were analyzed monthly (from July/1994 to June/1995), in seven subareas (terrestrial border and aquatic area) and physical and chemical parameters (depth, salinity, sediment texture, oxygen in water, organic material of sediment and water temperature) were registered. Decapoda from the families Grapsidae, Ocypodidae, Portunidae (Brachyura), Diogenidae (Anomura) and Penaeidae (Penaeidea) were captured. Chasmagnathus granulata Dana 1851 was found ali months near the canal connecting Atlantic Ocean and Lagoa do Peixe, but inside... |

| A study of the genus Leucosia Weber, 1795, led to the establishment of the identity of the type species, L. craniolaris (Linnaeus, 1758), designation of a neotype and redefinition of the genus. Leucosia is now restricted to 4 species: the type species L. craniolaris (Linnaeus, 1758), L. punctata Bell, 1855, L. moresbiensis Haswell, 1880, and a new species, L. rubripalma. They differ from all other species heretofore assigned to the genus in having first male pleopod with a screw-like tightly coiled shaft, terminating in a setose muff. The species are described or redescribed and illustrated, extended synonymies are given, and a key for their identification is provided. |

| O crescimento de Aegla longirostri Bond-Buckup & Buckup, 1994 foi analisado mensalmente de setembro de 1996 a agosto de 1997 no Rio Ibicuí-Mirim, Itaára, localidade de Val-de-Serra, Estado do Rio Grande do Sul, Brasil. O sexo dos espécimes coletados foi registrado e a medida do comprimento do cefalotórax foi tomada com um paquímetro. O crescimento foi estimado usando o modelo de von Bertalanffy. As curvas de crescimento em comprimento do cefalotórax (mm) de machos e fêmeas foram descritas, respectivamente, pelas equações: Ct = 27,9 [1 - e - 0,0069 (t + 24,78)] e Ct = 21,45 [1 - e - 0,0048 (t + 45,62)]. A idade máxima estimada para machos foi de um ano e nove meses e para fêmeas dois anos. |

| The crustaceans of the genus Aegla Leach, 1820 are found in streams, rivers and lakes from Franca, São Paulo, Brazil (20º60'S, 47º40'W), to Ilha Madre de Dios, Chile (50º01'10"S, 75º18'45"W) in South America. The growth and cheliped asymmetry of Aegla platensis Schmitt, 1942 were analyzed. The animals were collected from July 1997 to September 1998 at Arroio do Mineiro, Taquara, Rio Grande do Sul, Brazil (29º46'S, 50º53"W). The sex, length, width of the carapace and the total weight of the crab were registered. And after that, the animals were returned to the stream. In the statistical analysis von Bertalanffy's model was used. The growth curves in length (mm) of males and females are described, respectively, by the following equations: L1 = 17.39 [1 - e... |
