Planche 14 Issued from : C. Razouls in Ann. Inst. océanogr., Paris, 1994, 70 (1). [p.148]. Comparison of varieties robusta and antarctica.
1: anal segment and caudal rami from robusta robusta; 2: same, from robusta antarctica; 3, P5 female from Pleuromamma sp. (Kerguelen Islands).
Un individu femelle récolté à la station ''Kerfix'' (Ïles Kerguelen) présente des caractères qui ne permettent pas de l'attribuer en toute certitude à P. robusta antarctica
- La longueur totale est de 4,48 mm.
- Pr/Ur = 1,83.
- A1 comme in Steuer (1933, fig.56).
- La tête et le Th1 présentent une ligne de suture fine et complète.
- La P5 est tout à fait comparable à celle figurée in Steuer (1933, p.5, fig.13 ou p.15, fig.65), et non comme celle de P. robusta in Steuer (1933, p.12, fig.51) ou in Vervoort (1951, p.126, fig.69b).
- Les proportions de l'urosome sont en %: 32,9/28,7/20,4/F = 17,9.
- Le segment génital montre une spermathèque en position très antérieure comme chez P. robusta.
- L'opercule anal est lisse.
- Les rames caudales (Furca) ne montrent aucune trace de poils sur les bord internes; Lg/lg = 2,0.
- Par comparaison avec P. robusta antarctica la P5 montre qu'à l'apex du segment distal la soie la plus externe est la moitié de la suivante, elle-même un peu moins de la moitié de la plus longue.

Un second individu femelle examiné présente une longueur totale de 4,22 mm. Pr/Ur = 2,08; les rames caudales présentent des soies longues sur les bords internes; l'opercule anal est lisse; la P5 comme chez P. quadrungulata, mais les A1 totalement sans dents ou pointes.

Occurrence of Pleuromamma robusta in all longitudes around Antarctic zone of the Southern Ocean.
The percentage frequency of occurrence in samples taken within every 20° of longitude.

Nota: During the 'Discovery' investigations some thousands of plankton samples have been taken from stations spread over the whole of the Southern Ocean at all seasons of the year, the majority south of the Antarctic Convergence. An arbitrary selection of samples has been made from hauls between the surface and a depth of 250 m, which means that they have been taken from within the limits of the Antarctic surface water.

Study area and samplingb stations in the Eastern Tropical Pacific Ocean.
The six geographic zones identified in the analysis: Western coast of the Baja California peninsula (a), Mexicvo's coastal region (b), Mexsico's oceanic region (c), central coastal region (d), central oceanic region (e), equatorial oceanic region (f).
Ninety-six zooplankton samples were collected with a Bongo net (333 Mm mesh size) towed obliquely from 200 m. An average of 438 m³ of water was filtered by tow. Sampling began in July near the Baja California and continued toward equator until December 2003.
The sampling area comprises a large area in the Eastern tropical Pacific Ocean (ETPO) located between the subtropical gyres of the North and South pacific in tropical Surface Water (TSW); this water is characterized by surface temperature > 25°C and Salinity < 34. Sampling locations encompassed parts of the eastern Pacific warm pool, the North Equatorial Countercurrent, the North Equatorial Current, and the southern terminus of the California Current. The area is also influenced by the California Current (cold waters) and the Costa Rican Coastal Current (warm waters. In this sense, physical and chemical characteristics of the sea influence the community structure dynamics of pelagic copepods.

Note the differences with pleuromamma abdominalis and P. gracilis; P; robusta seems in this region more strictly carnivorous.

Sampling depth (Antarct., sub-Antarct.) : 200-1000 m. 0-197 m at Station S 2 in S Bösö (E middle Japan).
Les dimensions données (290) par Chen & Zhang (1965) sont exceptionnellement minimales.
D'après C. Séret (1979, p.141) l'espèce effectue des migrations verticales importantes entre la surface et 1500 m. Elle est absente de la surface le jour et se concentre essentiellement vers 600 m. La nuit, son effectif est abondant en surface.
