Nota: Samples collected in May-June 1974 with an opening-closing bongo nets (mesh apertures of both nets 0.330 mm and 0.220 mm) from Baja California to Galapagos Is.
Nota: This species was the one of most abundant copepods (12.8% of the total catch in combined day and night samples. The trend of vertical distribution was similar to that of E. subtenuis, occurring mainly above 200 m, but the overall vertical range was deeper. The vertical range of males was shallower than that of females and extended to 250 m in day samples and 150 m in night samples. (see chart Figs.1, 12, 13 in Eucalanus subtenuis). |

For Itoh (1970 a, fig.2, from co-ordonates) the Itoh's index value of the mandibular gnathobase = 185.
After Mulyadi (2004, p.118) the close similarity between this species and S. pileatus has led some authors (Deevey, 1960; Lang, 1963; Roe, 1972) to treat the wo as one taxon, and to suggestions that they may be conspecific (Grice, 1962; Bjornberg, 1963). Grice (1962) noted the differences between females of the two species, and a detailed description of S. pileatus by Vervoort (1946) stated that there are 4 setae on the basis of mandible.
