Chart showing the geographical distribution (white triangle) 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). |

Sampling depth (Antarct., sub-Antarct.) : 500-1000 m.
Concerning males see remarks to C. indicus from Tanaka & Omori (1992, p.260-261).
For Vervoort (1963 b, p.34), the occurence of this species in the Gulf of Guinea, is a surprise, but there is no doubt about their identity. it is thus necessary to revise previously expressed opinion that the species is a characteristic Antarctic deep water copepod; The species probably has a much wider distribution in deep water of the Atlantic Ocean, penetrating into the deeper waters of the Antarctic. In the Indian sector of the Antarctic, the species has also been recorded from north of the Antarctic convergence and in the extreme south of the Indian Ocean. Wolfenden (1911) mentions one tropical locality (0°46'N, 18°59'W which is in the vicinity of Atlantide Expedition (1°30'N, 10°10'W). | | | Last update : 28/01/2017 | |
