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.

. Lecithotrophic. Body narrowly ovate in dorso-ventral view; about 1.6 times as long as wide; lateral margins with only modest discontinuity in body outline between cephalic shield and trunk. In lateral view, trunk axis bent downwards ca 10–20° with respect to cephalic axis. Length 210–240 µm (without dorso-caudal spine), greatest width ca 120 µm, greatest dorso-ventral thickness ca 80 µm. Labrum weakly elevated, hoe-shaped in ventral view, approximately 1.2 times as long as wide; surface divided into plates by cuticular ridges; pore pattern not examined in detail but at least three pores present in midline: one anteriorly, two posteriorly. Caudal end acuminate, terminating in ca 30 µm long dorso-caudal spine usually with two or three annuli, this being upturned ca 10–20° with respect to trunk axis and accompanied ventrally by pair of furcal double-spines ca 5 µm long (i.e., each furcal spine bifid from base).
