Current research analyzed the behavioral activities of Macrobrachium rosenbergii and its preference for colored shelters in male monosex, female monosex and mixed culture. Ten shrimps m-2 were maintained in eight 250-L aquaria. Three artificial shelters, colored red, black and orange, were placed in each aquarium. Four aquaria were maintained in light/dark photoperiod respectively between 6h00 am and 6h00 pm and between 6h00 pm and 6h00 am, whereas the other four aquaria were submitted to an inverted photoperiod. The animals were observed for 30 days by Focal Animal Method for 15 minutes, with instantaneous recording every 60 seconds, at six different instances within the light and dark phases. Preference for black shelters occurred in male monosex and... |

The aim of this study is to describe the ultrastructure of the hepatopancreas of P. argentinus in intermoult. P. argentinus hepatopancreas was studied using standard TEM techniques. Each tubule consists of four cellular types: E (embryonic), F (fibrillar), R (resorptive) and B (blister like). E-cells have embryonic features and some of them were found in mitosis. F, R and B cells possess an apical brush border. F-cells have a central or basal nucleus, a conspicuous RER, and dilated Golgi cisternae. R cells show a polar organization of organelles in three areas: apical, with numerous mitochondria and sER tubules, a central area with the nucleus and RER, and a basal area containing a sER-like tubule system and mitochondria. B-cells were observed at different... |

This work describes the morphology and histology of the P. argentinus digestive tract. The foregut comprises the mouth, oesophagus, and stomach and is lined by a simple cylindrical epithelium overlain by cuticle. There are tegumental glands in the oral region and in the first portion of the oesophagus and of the hindgut. The cardiac stomach is an oval dorsal sac in the cephalothorax and has no calcified structures. The pyloric stomach comprises an upper chamber and a lower gland filter. The filter consists of an outer row of elongated setae and an inner row of dorsally curved setae forming longitudinal channels 16-18µm wide. The midgut runs from the dorsal chamber of the pyloric stomach to the sixth abdominal somite without caeca. The hindgut runs from the... |

O número de ovos e a taxa na qual eles são produzidos podem fornecer uma indicação do potencial reprodutivo de uma espécie. O objetivo deste estudo foi levantar dados básicos sobre a biologia geral de E. oplophoroides e, em particular, sua fecundidade na região de Ubatuba, SP. Os espécimes foram coletados em arrastos camaroneiros na Enseada de Ubatuba, SP (23ºS/45ºN), no período de junho/1995 a maio/1996. O número de ovos relacionados a uma dimensão corpórea (comprimento cefalotorácico) foi ajustado a uma regressão linear. A fecundidade média obtida foi de 2.742 ± 1.561, variando de 434 a 5.215 ovos por fêmea por desova e o volume médio dos ovos foi de 0,015 ± 0,002 mm³. A fecundidade aumentou proporcionalmente com o tamanho de E. oplophoroides. Não houve... |

Species of shrimps are revised based on bibliographic information and on specimens collected with an Agassiz trawl (AGT) during the PUCK-156 Expedition (2001) onboard R/V Sonne in three areas along Chilean coast; off Antofagasta (22° lat. S), off Concepción (36°lat. S) and off Chiloé (42° lat. S). 111 specimens belonging to 12 species were collected, including three new records for the Chilean fauna; Metacrangon procax, Nematocarcinus productus, and Merhyppolite sp. aff. M. americana. Presence of Nematocarcinus lanceopes, Lebbeus antarcticus, Pandalopsis ampla and Sclerocrangon atrox in the collected material allows extension of their distributional ranges from sub-Antarctic to temperate areas |

The bathypelagic shrimp genus Pasiphaea Savigny, 1816 (Caridea: Pasiphaeidae) has been previously known from Taiwan from only three species. However, recent deep-sea surveys around the island have collected numerous specimens comprising ten species, of which four are new to science: P. aeons n. sp., P alcocki (Wood-Mason and Alcock, 1891), P exilimanus n. sp., P. falx n. sp., P japonica Omori, 1976, P. mclaughlinae Hayashi, 2006, P levicarinata Hanamura, 1994, P orientalis Schmitt, 1931, P. sirenkoi Burukovsky, 1987 and P. taiwanica n. sp. The four new species are fully described and illustrated, and compared with allied congeners. Pasiphaea orientalis is redescribed, as this species is endemic to Taiwan and its original description is inadequate. Amongst... |

A taxonomic review of the two genera of the family Alvinocarididae (Decapoda: Caridea), Rimicaris Williams and Rona, 1986 and Chorocaris Martin and Hessler 1990, is presented based on study of type materials and/or supplemental material from recent collections. Two species of Rimicaris, R. exoculata Williams and Rona 1986 and R. kairei Watabe and Hashimoto 2002, and three species of Chorocaris, C. chacei Williams and Rona 1986, C. vandoverae Martin and Hessler 1990, and C. paulexa Martin and Shank 2005, are recognized. All species are exclusively associated with deep-water hydrothermal community. Close relationship between the two genera is confirmed by morphological characters, but the monophyly of Chorocaris is not corroborated. An examination of a good... |

A new species of hippolytid shrimp, Lebbeus africanus spec. nov. is described from the continental slope off Mauritania, eastern Atlantic. A comparison with related species is made. Lebbeus bidentatus Zarenkov, 1976, L. carinatus Zarenkov, 1976, L. curvirostris Zarenkov, 1976, and L. saldanhae Barnard, 1947, are redescribed and their taxonomic status is discussed. |

This study deals with Caridean fauna living between the leaves of New-Caledonian seagrassmeadows (Cymodocea sp. principally) from zero to about eight meters and sampled during day and night. Twenty species (all figured) were caught (excluding Alpheidae). All are known. Nevertheless, in some cases, small variations have been observed by comparison with the same species from other areas. Presently, 70 species are recognized from New-Caledonian marine waters, including the 17 species reported in this papier for the first time from that region. Comparison with Caridean fauna of seagrass-meadows of other areas (Australia, Japan, Madagascar) shows a very important resemblance between them. |

Species of the genus Pontonia Latreille, 1829, are distributed in tropical and subtropical waters around the world, living in association with either molluscan or ascidian hosts. In the present taxonomic revision, Pontonia sensu lato is divided into six genera: Pontonia sensu stricto; Ascidonia gen. nov., Rostronia gen. nov., Dactylonia gen. nov., Odontonia gen. nov., and Bruceonia gen. nov. A total of 29 species is described and figured, four of which are new to science: Pontonia pilosa spec. nov., Dactylonia holthuisi spec. nov., Odontonia rufopunctata spec. nov., and O. seychellensis spec. nov. The division in six genera is based on a stepwise phylogenetic analysis using morphological characters, performed using PAUP and McClade software. The... |
