A study on octopodids from the eastern Weddell Sea, Antarctica
A comprehensive study of octopodids in the Weddell Sea was conducted during cruise ANT XIII/3 of RV "Polarstern". The study yielded eight species or incirrate octopodids, three of which were undescribed. There appeared to be no differences in octopodid species assemblage in the two samplin...
