The y-naupliar morphospecies are listed in descending order of abundance in 2018 and 2019 (column 4). Developmental time to cyprid and mean body length of last-stage nauplii (LSN) are shown, along with calculated rearing success to LSN or cyprid, degree of overlap in occurrence in both years, and correlation between morphospecies abundance and size (see Fig. 20). The data are extracted from the more comprehensive supplementary Table S1.

In lateral view, body axis bent downwards 30° with respect to cephalic axis. Length ca 250 µm (without dorso-caudal spine), greatest width ca 130 µm, greatest dorso-ventral thickness ca 80 µm. Labrum balloon-shaped, with surface divided into facets by cuticular ridges, midline produced into keel-like elevation, and free posterior margin bearing small median spine; pores not examined. Caudal end attenuate, terminating in 75–80 µm long, slightly dorsally curved dorso-caudal spine bearing small spines; spine upturned ca 20° to trunk axis and accompanied ventrally at base by pair of ca 10 µm long triangular furcal spines.

Variation is seen among nauplii in the form of the dorso-caudal spine (either broad-based and more or less straight or more slender and curved); in the morphology of the posterior margin of the labrum (spine sometimes absent/diminutive, margin sometimes weakly serrate); and among unmolted cyprids in the number of lipid vesicles.</paragraph>
