Shrimp of the family Atyidae are important members of nearly all tropical (and most temperate) fresh and brackish water ecosystems in the world. To date, a complete mitochondrial genome from this important crustacean group has not been reported. Here, we present the complete mitochondrial DNA sequence of the Hawaiian atyid Halocaridina rubra [Holthuis, L.B., 1963. On red coloured shrimps (Decap...

Decapod crustaceans were studied in the Marquesas Islands, French Polynesia, between 50–550 m by using a remotely operated vehicle (ROV) equipped with high resolution cameras and an articulated arm. Careful examination of videos and photographs combined with previous inventories made in the area with conventional gears allowed the identification of 30 species, including 20 species-level determi...

A new amphi-Atlantic snapping shrimp of the genus Alpheus Fabricius, 1798, Alpheus buckupi spec. nov., is described and illustrated based on material collected from the western (Orinoco Delta, Venezuela to São Paulo, Brazil) and eastern Atlantic (São Tomé and Príncipe). The new species is morphologically similar to members of the A. lobidens De Haan, 1850 species complex, from the Indo-Pacific,...

A new coral-associated species of the genus Hamodactylus is described from Lembeh Strait, NE Sulawesi, Indonesia. The three other known species in the genus have been recorded in association with octocorals. The single ovigerous female specimen of the new species was collected from a scleractinian host. It can be easily separated from its congeners by the very long eyestalks and the chela of th...

The present study deals two new alpheid shrimp species from the transisthmian Salmoneus ortmanni (Rankin, 1898) complex. Salmoneus alvarezi sp. nov. is described based on materials collected in Bahía Málaga, Colombia, and Punta Morales, Costa Rica, and is closely related to the western Atlantic S. ortmanni and S. wehrtmanni Anker, 2011. Salmoneus malagensis sp. nov. is described based on specim...

Alpheus brevicristatus De Haan, 1849, one of the largest alpheid shrimps, is known to occur in Korea Strait and Yellow Sea of Korea, Japan, and Taiwan (Kim, 1977; Banner and Banner, 1984; Jeng and Chang, 1985). It inhabits shallow burrows in soft mud flats of estuary and Zostera belts of bay bottom (Miya, 1971) and lives in a symbiotic association with the gobies (Banner and Banner, 1982). Very...

Macrobrachium ohione is a migratory (amphidromous) river shrimp (Decapoda, Caridea) that may be parasitized by the branchial parasite Probopyrus pandalicola (Isopoda, Bopyridae). The parasite disrupts gonadal maturation and spawning in female shrimps, resulting in the total loss of reproduction. Shrimps are usually infected by bopyrid parasites during the late zoeal or early postlarval stages; ...

Samples and images of deep-water benthic decapod crustaceans were collected from the Nikko Seamounts, Mariana Arc, at depths of 520-680 m, by using the remotely operate vehicle "Hyper-Dolphin", equipped with a high definition camera, digital camera, manipulators and slurp gun (suction sampler). The following seven species were collected, of which three are new to science: Plesionika unicolor n....

Output from the olfactory lobe (primary olfactory center) of eumalacostracan crustaceans is transmitted to the medulla terminalis (MT) and hemiellipsoid body (HB) in the lateral protocerebrum (higher order center) by a large population of projection neurons. In eureptantian crustaceans (lobsters, crayfish, and crabs), these projection neurons also form the output pathway from an additional neur...
