A new snapping shrimp, Alpheus lutosus spec. nov., is described from the intertidal mudflats of Bubiyan Island, northern Kuwait, south of the vast Shatt-Al-Arab delta. The new species appears to be closely related to Alpheus hoplocheles Coutière, 1897 from similar estuarine habitats in China and Japan, differing mainly in the absence of a sharp distolateral tooth on the palm of the major chela, the less marked rostral carina, and the number of spines on the propodus of the third pereiopod. Both A. lutosus spec. nov. and A. hoplocheles are unique within the A. edwardsii species group in having a strong sharp distomesial tooth on the palm of the otherwise typical edwardsii-type major chela. At the type locality, A. lutosus spec. nov. is often associated with... |

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... |

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... |

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... |

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. |

Two new species, Palaemonella aliska spec. nov. and Vir longidactylus spec. nov. are described from Nhatrang Bay, Vietnam. Palaemonella aliska spec. nov., collected from the holes burrowed by Alpheus cf. bellulus Miya & Miyake, 1969 and an unidentified goby, clearly diff ering from the remained species of the genus by its highly developed dorsal rostral carina, reaching to the mid-lenght of the carapace, and the presence of three well developed dorsal teeth situated on the carapace posterior to the orbital margin. Vir longidactylus spec. nov., collected on colonies of the caryophyllid coral Physogyra lichtensteini Edwards & Haime, 1851, diff ers from all species of the genus by its highly produced sharp molar process of the mandible and the... |

Abstract Studies on fecundity and embryo size have been frequently used to infer about the reproductive potential, embryogenesis, and the energy investment in embryo production in crustaceans. These parameters are relevant to the knowledge of life-history and diversity of reproductive strategies developed by this group. This study addressed the embryo production by the estuarine shrimp Salmoneus carvachoiAnker, 2007, a poorly known caridean shrimp. We investigated whether there was (1) a correlation between fecundity and carapace length, (2) an increase in embryo volume along the embryonic development, and (3) loss of embryos along development. In addition, we investigated whether the esternite length and height and width of the pleura of the second... |

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... |

The first description of the larval stages of a representative of the family Rhynchocinetidae from the southeastern Pacific coast of South América is presented. Larvae of the rock shrimp Rhynchocinetes typus, from rocky subtidal environment of the Chile-Pera coast were reared in the laboratory at 22 °C, salinity 32 and feeding with Anemia franciscana. Seven zoeal stages, which occur through 10 successive moults, are described and illustrated in detail. Morphological comparison made between R. typus and other congeneric and related species belonging to Rhynchocinetid showed the main characteristic for the diagnosis of zoeal stages are: (a) the pereiopods appear in the third stage, (b) the exopod of the antennae have six segments, and (c) no pleopods were... |
