Espèce Centropages velificatus - Carte de distribution 3issued from : M.H. Bundy & C.-A. Paffenhöfer in Mar. Ecol. Progr. Ser., 1996, 133. [p.103, Fig.2].
Feeding current of a tethered female Centropages velificatus (cephalothorax length = 1.2 mm), collected off the coast of Georgia (USA), feed with Gymnodinium nelsoni and Thalassiosira eccentrica. After acclimatation, the copepods were placed in complete darkness prior to videotaping in a 6 l cubic vessel, in the dark.
a: Flow field velocity. Contours represent fluid speeds and are plotted at 1 mm/sec intervals.
b: Flow field geometry. Vectors indicate direction and magnitude of flow.
Espèce Centropages velificatus - Carte de distribution 4Issued from : J.C. Roff, J.T. Turner, M.K. Webber & R.R. Hopcroft in Aquat. microb. Ecol., 1995, 9. [p.170, Table 5].
Summary observations on naupliar bacterivory on FLB (fluorescently labelled bacteria) a partir Escherichia coli (±0.7 µm3 cell volume) in Kingston Harbour and Lime Cay (Jamaica).
Fluorescence levels: 0 = no materal for observation; - = no fluorescence observed; + = low fluorescence due to few FLB observe; * = highly fluorescence due to many FLB.

The authors show of the 11 species examined (Centropages velificatus, Acartia lilljeborgi, Paracalanus aculeatus, Temora stylifera, Undinula vulgarius, Euchaeta marina, Clausocalanus spp., Onaea sppp., Corycaeus spp.), 7 showed clear evidence of feeding on FLB (see table 5), with 92% of their nauplii ingesting FLB, clearly visible in the guts of many nauplii, and usually comprisised a discrete feeding (foregut) or 'fecal' (hindgut) bolus of cells. After only 30 min, fecal pellets were being produced already filled with FLB. Presence of FLB in guts cannot be interpreted as incidental feeding or 'drinking', because 4 species failed to ingest them (Centropages velificatus, Euchaeta marina, Clausocalanus sp., Corycaeus sp.). The very earliest stages may not ingest bacteria or other particles because they may have yolk reserves (for example Temora turbinata N1 nauplii did not ingest FLB, but later stage nauplii did).

Rem.: Espèce distincte ou variété atlantique de Centropages furcatus . Cf. Rem. à Centropages furcatus velificatus.
L'espèce signalée par Krumme & Liang ( 2004) appartient sans doute à cette forme.
After Acha & al. (2020), this species is present in summer northern shelf in the SW Atlantic.
