| Summary: | Figure 16. Ophiothrix fragilis postlarval development. A–C, 0.34 mm dd postlarvae; A, on arm of adult; B, dorsal, note the large central plate (CPP); C, ventral, note the tricuspid tooth; D–G, 0.55 mm dd postlarvae; D, arm dorsal, note the small terminal plate (TP) and large hooks; F, arm lateral; G, ventral; H, I, 0.8 mm dd postlarvae; H, dorsal, radial shields (RS) and inter-radial plates (IR1, 2) have formed; I, ventral; J, K, 1.1 mm postlarvae; J, dorsal, note the k-plate; K, ventral, note the first tooth papillae (TPa); L–N, 1.3 mm postlarvae; L, dorsal with numerous disc spines; M, ventral with additional TPa; N, arm dorsal, note the serrated shape of the proximal dorsal spines. Abbreviations: as in Figs 1–3, 5. Scale bars in millimetres. Some dorsal plates have fallen off due to the bleaching process (H, J).
