Lecithotrophic y-naupliar morphospecies (‘Types’) successfully reared during fieldwork at Sesoko Island (Okinawa) in 2018 and 2019, based on 5137 sampled lecithotrophic nauplii, with sporadic data added from earlier sampling in 1991–2005. 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. Asterisks (e.g., Types A*, D*, E*) are added to the designations of morphospecies that exhibited molecular variation among specimens in Dreyer et al. (2023a) and might therefore represent more than one biological species." httpUri="http://table.plazi.org/id/B9C307BD0A3F1E0D3BB261DEFDED95B1" pageId="17" pageNumber="18" tableUuid="B9C307BD0A3F1E0D3BB261DEFDED95B1">Tables 1 and S1</tableCitation>

In lateral view, trunk axis downturned 30–45° relative to cephalic axis. Length 250–275 µm (without dorso-caudal spine), greatest width 150 µm, greatest dorso-ventral thickness 70 µm. Labrum weakly elevated, broadly trapezoidal with rounded posterior corners and approximately as long as wide; not divided into facets by cuticular ridges; bearing five pores: row of three posteriorly in midline and pair in left and right postero-lateral corners. Caudal end rounded, terminating in short (ca 7–10 µm), conical dorso-caudal spine and pair of short (10 µm), broad, upwardly curved furcal spines.</paragraph>

Easily recognizable by the combination of its obtuse-ovate shape, distinctive black-brown-orange coloration (on which the nickname is based) and the three short, broad caudal spines. There is very little variation among specimens except for changes in pigment distribution as cyprid development progresses within the LSN cuticle, and only insignificant molecular variation was found among seven sequenced specimens (Olesen
