چکیده
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 determinations. Species identified belong to shrimps (Penaeoidea, Stenopodidea, and Caridea), lobsters (Astacidea and Achelata), anomurans (Galatheoidea and Paguroidea), and brachyuran crabs (Dromioidea, Homolodromioidea, Raninoidea, Leucosioidea, Majoidea, Parthenopoidea, Portunoidea, and Trapezioidea). Most of these species were observed and photographed in situ for the first time. A discussion is given on the geographic distribution, density, ecology, and behavior.

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....

In the past only very few works dealt with fossil decapod crustaceans from Slovakia. The systematic research of this group has never been fully conducted there. This contribution provides a short review of all known Mesozoic and Cenozoic fossil decapod occurrences. So far, most of the taxa were described from the Eocene and Miocene strata.

A new crab Liomerinae, Neoliomera moana sp. nov., is described from the Marquesas Islands, based on three specimens collected by hand at the entrance of submarine caves at depths of 6-28 m. Within the genus the new species belongs to a group of six species that have the carapace cristate on the anterolateral margins. It can be recognized by the presence of a double crest on the upper margin of ...
