Distribution map of Subeucalanus longiceps by geographical zones

Chart showing the geographical distribution (white circle) in the seas surrounding the Antarctic continent.
Nota: In this chart the area frequented by whaling vessels has been hatched. The Antarctic circle (66°.5 S) has been drawn as a broken line. The numbers I to VI refer to the sectors into which the Antarctic seas are divided according to Mackintosh (1942) (after Vervoort, 1951).

Eucalanus longiceps (= Subeucalanus longiceps) from Scotia Sea.
Median and interquartile ranges of copepods (nos /m2) in the five water zones; from north to south these are SAF Subantractic Front area, PFZ Polar frontal Zone, PF Polar Front area, AZ Antarctic Zone, WSC Weddell-Scotia Confluence area/ East Wind Drift.
Numbers on the plots are upper interquartiles where these could not be scaled.

Observed by Dias & al. (2010)) in Intermediate Antarctic water (Brazil).
After Arashkevich (1978) the diets of the species are pennate diatoms (mainly in the gut content), and mess frequent: centric diatoms, flagellates, tintinnids, crustacea, shapeless mass.
