By far the most frequent species was Haploniscus bicuspis with 11,410 specimens sampled at 136 stations (Table 1). H. foresti and A. simplex were also fairly frequent, occurring at 19 and 12 stations, with 1375 and 1816 specimens, respectively.

Haploniscus bicuspis has been reported to be adapted to cold conditions around 0°C (Hansen 1916; Wolff 1962), and was here reported in many instances from temperatures below zero (as low as -0.86°C), but even at temperatures as high as 7.11° C.

Distribution of Haploniscidae at the Greenland-Iceland-Faeroe Ridge Ten species of the Haploniscidae were sampled during the BIOICE expeditions in the GIF area (Table 1, Figs 10– 12), eight species of Haploniscus and one species each of genera Antennuloniscus and Chauliodoniscus.
