Bathykorus bouilloni: a new genus and species of deep-sea jellyfish from the Arctic Ocean (Hydrozoa, Narcomedusae, Aeginidae)
نویسنده
چکیده
A new genus and species of a common deep-water narcomedusa is described from the Arctic Ocean. The species has four primary tentacles, four secondary tentacles, with three interradial manubrial pouches in each quadrant. A revision and taxonomic key of the family Aeginidae is presented to account for the new genus. Detailed information on its finescale vertical and horizontal distributions show that it occurs in a fairly narrow depth range between 1400–2000 meters. The species was observed 423 times at eleven stations, demonstrating that new species can be common in the underexplored regions of the ocean.

Comparisons were made with the type of the genera Maorithyas Fleming, 1950, Spinaxinus O...
متن کاملSympagohydra tuuli (Cnidaria, Hydrozoa): Wrst report from sea ice of the central Arctic Ocean and insights into histology, reproduction and locomotion
Various cnidarians have adapted their life style to interstitial habitats of marine sediments. Recently, for the Wrst time a hydroid was reported from the interstitial brine channel system of Arctic fast ice. Due to its derived features, the new genus and species Sympagohydra tuuli was introduced. Here we describe Wndings of S. tuuli in sea ice at several sites within the central Arctic Ocean. ...
