The survey area was located predominantly within the seasonal ice zone, and in the month prior to the survey there was considerable ice coverage over the western section but none over the east.

Species Oithona frigida - Distribution map 8

Map 8 Issued from : D.W. Pond in J. Plankton Res., 2012, 34 (6). [p.450, Fig.7]
The Southern Ocean copepod, Oithona frigida with multiple oil vesicles throughout the body, although these are often concentrated in the lower prosome. Lipids reserve are, generally, linked to locomotion and/or feeding behaviour.

Nota: The solid-liquid phase transitions of lipids are a factor regulating the buoancy of the copepods. These phase transitions are controlled in relation to the physical environment, through the selective accumulation of specific lipids with optimum levels of unsaturation. The necessity to control buoyancy and maintain an optimum depth is a fundamental evolutionary force, driving anatomical, biochemical and behavioural adaptations within the aquatic realm. It is hypothesized that each species adjusts the amount, composition and anatomical location of lipids, to maximize fitness according to the preferred habitat and life history traits.

Remarks

epi-bathypelagic.
Sampling depth (Antarct., sub-Antarct.) : 0-1000 m.
Certain locality records in the subtropical Atlantic and in the Mediterranean Sea result from a confusion with O. pseudofrigida. For Vervvort (1951, p.149) a closely related form, differing from the typical O. frigida in the spinulation of the swimming legs (the number of outer edge spines on the P3 and P4) has been described as O. frigida var. pseudofrigida Rosendorn (1917 a, p.19) from the Atlantic and Indian Oceans.
Nishida (1985, p.48) points to this species and closely allied O. pseudofrigida possess 2 setae on the free segment of P5, but are closely related to O. plumifera and O. setigera and quite different from those species placed in Dioithona by Kiefer (1935). This suggests that the present subgenus Dioithona, as presently defined, does not represent a monophyletic group.
Wend-Heckmann underlines that the rostrum is hepful to differentiate between O. similis and O. frigida , because the forhead of O. frigida has a rostrum that can be seen from dorsal view while the one of O. similis is directed ventrally and cannot be seen in the dorsal view.
