Second maxilla (Mx2) and maxilipeds from Scaphocalanus echinatus (e), Scottocalanus helenae (f) and Scottocalanus securifrons (g).
Scale bars: Mx2 = 100 µm (e, f); 200 µm (g); Mxp = 100 µm (e); 200 µm (f, g).
The setae of the second maxillae in Sco. securifrons, Sco. helenae, and Sco. echinatus are similar in shape to specialized chemosensory setae; among these, the setae in Sca. echinatus are relatively fine. The maxilipeds of Sco.helenae and Sco. securifrons have short, stout setae, Sca. echinatus have fine plumose setae (as in Calanus sinicusThe feeding appendages (Mx2 and Mxp) appear suitable for feeding on fine particulate organic material contrary of Scottocalanus helenae and Scottocalanus securifrons Compare figures of setal armament from three species in the two genera).
