Notes
443 records
The reported geographical range for this species is from 63°N to 52°S, but its occurrences are erratic and disjunct. Off Bermuda in March 1974 juveniles swarmed in such great abundance in the upper 100m that it was by far and away the dominant epipelagic halocyprid at the time. Adult females were a little deeper in the water column but males were quite rare and restricted to depths of 600-800m. In the NE Atlantic its occurrences are generally rare. However, in September 1979 large numbers of adult females were collected at depths of 1500m within 10-100m of the continental slope over the Goban Spur off the Southwest Approaches off Britain. This raises the question as to whether the two collections of specimens off Bermuda and the Goban Spur were same species, or does this species undertake remarkable ontogenetic or seasonal migrations?
