Head and heart development in post-hatching stages (66-168 h). (A) post-hatching stage (66 h); (B) early pharyngula period (72 h); (C) high-pec stage (96 h); (D) protruding-jaw stage (120 h); (E) open-mouth stage (144 h); (F) one-week larvae (168 h). (G-I) The developing heart at 66 h (G), 96 h (H) and 168 h (I). Abbreviations: agp, adhesive gland primordium; at, atrium; av, atrio-ventricular valve; cb, cerebellum; dag, dorsal adhesive gland; fb, forebrain; gi, gills; he, heart; ht, heart tube; ir, iridophores; l, lens; lj, lower jaw; hm, head melanophores; mb, midbrain; mhb, midbrain-hindbrain boundary; ov, otic vesicle; pfb, pectoral fin bud; rh, rhombomeres; v, ventricle; vag, ventral adhesive gland. A-F, I: Scale bar = 500 μm; G: Scale bar = 200 μm; H: Scale bar = 100 μm.
