Recent trawling in the Southern Ocean has yielded an unusual and relatively large collection of deep-sea octopods, comprising four species in two genera. Several deep-sea genera, which are inadequately characterised, […]
Graneledone verrucosa (Verrill 1881), the type species of the genus Graneledone, is redescribed based on historical material and previously unreported specimens that have resulted from an increase in deep-sea fishing […]
The syntypes of the endemic Southern Ocean octopodid Pareledone polymorpha (Robson, 1930) were re-examined and measurements, counts and indices are presented. The two forms described by Robson, namely oblonga and […]
Small benthic octopodids of the genus Pareledone are commonly found around the shelf area of the sub-Antarctic island South Georgia but little is known about their biology. During three consecutive […]
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 […]
The capture of 52 specimens of the cirrate octopod Grimpoteuthis glacialis (Robson, 1930), of dorsal mantle length 20-165 mm during a 1996 trawling survey near the Antarctic Peninsula allowed the […]
Beak shapes in nine species of Southern Ocean octopodids were measured using seven size-standardized ratios. The results were analysed using principal component analysis and discriminant function analysis and show that […]
Noise burst events observed at Sodankylä, Finland, in the frequency range 20–25 kHz during January–April 2005 last up to 4 s, occur more often at midnight, are associated with high […]
Samples of the Antarctic octopus Pareledone turqueti were taken from three locations on the Scotia Ridge in the Southern Ocean. The genetic homogeneity of these populations was investigated using isozyme […]
During the past ten years, the Antarctic Peninsula has been identified as the most rapidly warming region of the Southern Hemisphere and it is important to place this warming in […]
This paper provides new observations of volcanic features and hydrological characteristics in and around Southern Thule, the southernmost group of islands in the South Sandwich Islands, including the first high-resolution […]
