On the occurrence and biology of some Antarctic Mysidacea (Crustacea)
10 species of Mysidacea were sampled during the Polarstern and Walther Herwig SIBEX cruises to the Antarctic Peninsula region from 1983 to 1986. The commonest were Antarctomysis maxima, A. ohlini and Mysidetesposthon. For these species the size and maturity stage composition as well as the length-we...
