Since
Chavtur
et al.
(2015)
have recently published a full and detailed description of this species, we are only providing a set of comparable drawings (of specimens collected in the Norwegian Sea at 65°N 20°W), and meristic data.
Table 1
compiles length data for the juvenile instars from three localities, 65°N 20°W (sampled throughout a year), in the vicinity of Svalbard at 77° to 82.5°N, and over the Canadian Deep in the vicinity of 75°N 161°W. It was the dominant halocyprid species at all three localities; these length data are remarkably consistent. However,
Chavtur
et al
. (2015)
reported finding a few smaller specimens, which had lengths that are consistent with the sizes we provide for
B. hopcrofti
below. These length data show there are no significant size differences across quite a broad latitudinal range, nor were any suggestions of there being seasonal variations evident in the data from 65°N 20°W, although the data are insufficient for rigorous statistical evaluation.
