Figure S2. Development of mudskipper larvae and juveniles after hatching. (A–N) Lateral views (A–D, E, G, I, J–N) and ventral views (F, H) of planktonic larvae at 4.0–11.0 mm TL (A–H; n = 1 each stage) and of benthic to amphibious juveniles at 14.5–21.1 mm TL (I-N; n = 1 each stage). (J, L) Magnified images. Arrowheads in (D) indicate fin rays in the caudal fin. Arrows in (D, E) and arrowheads in (G, I, K) indicate the primordia of the hypural and melanophores, respectively. af, anal fin; cf., caudal fin; df1, dorsal fin 1; df2, dorsal fin 2; lj, lower jaw; mf, medial fin; pec, pectoral fin; pel, pelvic fin; y, yolk. Scale bars, 100 μm in D, F, H; 500 μm in A-C, J; 1 mm in E, G, I, K–N. (PDF 311 kb
