The genus Rhachotropis has the widest horizontal and bathymetric distribution of all amphipod genera known worldwide. Characteristic species of Rhachotropis were collected at 3200 m depth in the Kuril basin of the Sea of Okhotsk. Morphological investigations

The genus Rhachotropis has the widest geographic and bathymetric distribution of all amphipod genera worldwide. Molecular and morphological investigations of specimens sampled around Iceland and off the Norwegian coast allow the first insights into

The amphipod genus Rhachotropis has a worldwide distribution. Four species new to science are described, increasing the total number of Rhachotropis species to 59. Only one species was previously known from New Zealand and none from the Ross Sea. Two

The life-histories and the secondary production of four dominant peracarid crustaceans (the mysids Boreomysis arctica and Parapseudomma calloplura, the amphipod Rhachotropis caeca, and the isopod Ilyarachna longicornis) in bathyal depths of the Bay

We have compared the distribution of mesopelagic, benthopelagic and benthic fauna between two areas: one on the continental side of the Catalan Sea (cCS: northwestern Mediterranean) and one to the SW of the Balearic Islands (SWB: southwestern Mediterranean)
