Chiroteuthis veranyi from the Atlantic sector of the southern ocean (cephalopoda: Chiroteuthidae)
Chiroteuthis veranyi (Férussac, 1835) (Cephalopoda: Chiroteuthidae) from South Georgia is described from material collected during the British Antarctic Survey’s Offshore Biological Programme. The material closely resembles C. veranyi from elsewhere and, in common with C. lacertosa, C. imperator and...
