The species recorded from the Atlantic Ocean are tabulated according to their systematic relationships. By clicking on a species name, an individual species page will open, where there is an outline diagram of an adult female carapace.

 Four further options are offered: -

  • Maps: Two standard maps of showing each species’s distribution in the Southern Ocean and globally.

    Maps

  • Notes: The notes on each species include the number of records on which the maps are based, which gives an idea of the frequency with which the species has been encountered and hence its commonness, and data on carapace lengths sizes of adults and juveniles instars, however, note that the length data are not always for Southern Ocean material.

  • Drawings: Sketches of the carapace shapes of adult females (A, B) and males (C, D); the first antennae and frontal organs and the endopodite of the left second antennae of females (E, F) and of males (G and H) and the details of the armature of the male first antenna setae (I). These will facilitate identifications of adults.

  • Bathymetric profiles: These are derived from the transect of stations approximately along 20°W conducted using opening closing nets by Discovery from 1966-1981. At each station a day and night series of stratified net tows were carried subdividing the upper 1000m into 100m horizons and coarser horizons to depths of 2000m (e.g. Fasham and Angel, 1975). Data from several of these profiles have not been published. In addition some very deep profiles were made to depths of 4000m.
