It can be extremely abundant in near-surface subantarctic waters, and two subspecies have been described P. serrulata serrulata, which typically has a clear sculpturing of longitudinally striae and occurs in the South Atlantic, and a subspecies P. serrulata laevisthat lacks sculpturing has been described from south of New Zealand. Regrettably in most reports no distinction has been made between the two subspecies, so it is uncertain as to whether there is a latitudinal or longitudinal division between these two forms. The apparent geographical divide in the records between the South Atlantic and south of Australasia is likely to be an artifact of the sampling coverage.   n Mean mm s.d.
