Food / chlorophyll / thermocline Species
Prefers eat zooplankton (carnivorous) (Kroon and
Ganssen, 1989)
Copepods, tintinids, hyperiids amphipods (Hemleben
et al, 1989; Bé, 1977); Prefers zooplancton (integer
better proteins), diatoms, epithelial tissue, adipose
tissue, muscle tissue (Anderson et al., 1979)
Diatoms (Spindler et al, 1984; Schiebel et al 2001);
but also Chrysophytes (Hemleben et al, 1989);
Dinoflagellates, epithelial tissue, adipose animal
tissue (Anderson et al., 1984)
Dinoflagellates, diatoms; nerve, muscle and adipose
animal tissues, copepods, pefers zooplancton /phyto
: Omnivorous (Anderson et al 1979), + larves de
polychètes (Hemleben et al, 1989)
Copepods, tintinids, ciliates (Hemleben et al, 1989),
Prefer zooplankton : epithelial tissue (Anderson et l
1979), copepods (Rhumbler, 1911; Spindler et al.,
1984).
Dinoflagellates, diatoms, muscle tissue (Anderson et
al, 1979); Diatoms, these algae are consistently
observed in the cytoplasm (Hemleben et al 1989)
Chrysophytes, diatoms, dinoflagellates, muscle
tissue (Anderson et al., 1979 ; Hemleben et al.,
1989). Algal prey (Bé, 1977); phytoplankton,
coccolithes (Schiebel et al 2000)
Below DCM (Deep Chlorophyl Maximum) (Fairbanks et
al, 1982)
Below the DCM (Deep Chlorophyl Maximum), highest
frequencies are found in regions where no deep chloro
Max is developed (Ottens, 1992) one of the main
controling vertical distribution The maximum abundance
of Globigerina quinqueloba was associated with higher
chlorophyll-a concentrations (Kuroyanagi and Kawahata,
2004)
Prolific below the thermocline (Pujol
et al 1995)

Diatoms, muscle tissue, epithelial tissue, thecate
algae (Anderson et al., 1979; Hemleben et al., 1989)
Diatoms, muscle tissue, epithelial tissue, thecate
algae (Anderson et al., 1979; Hemleben et al., 1989)
Phytoplankton, commonly diatoms (Hemleben et al,
1989)
Phytoplankton, commonly diatoms (Hemleben et al,

Silica-rich plume surface water could serve as a
major food source to N. dutertrei, prefers
phytoplankton (Kroon and Ganssen, 1989)
Carnivorous during adult spherique stage (copepods,
tintinids, ciliés), in PSS stage, more herbivorous
(Hemleben et al., 1989); The best adapted species
for catching copepods since it was the only sp we
were able to feed with an harpacticoid and have the
lowest digestion time for an Artemia (Spindler et al.,
1984)
adipose animal tissue, muscle tissue, carnivorous
(Anderson et al, 1979); Copepods (Artemia)
(Anderson and Bé, 1976); Copepods (Calanoida)
(Spindler et al., 1984)
Show a strong correspondence with the Chlorophyll-a
maxima during winter (Wilke et al., 2008)
High abundance at relative high abundance of chloro
(Kuroyanagi and Kawahata, 2004)
Correlation with chlorophyll-a concentrations r=-0,08 with
chloro a (Kuroyanagi and Kawahata, 2004)
Maximum of abundance in the Deep Chlorophyl
Maximum (DCM) (Fairbank and Wiebe, 1980, Fairbanks
et al, 1982)
Below thermocline at the end of the summer (Pujol et al,
1995)
Deep thermocline (Lohmann and
Schweitzer, 1990); in the lower part
of the thermocline whan the base of
summer thermocline is < 16°C
(Cléroux et al 2007)
