Morphological effect of extracts on zebrafish embryogenesis after 96 h of exposure (hpf). (A–B) 96 hpf embryo during control and non-toxic concentration exposure demonstrated straight spine, normal body shape, normal heartbeat, round yolk sac and high intensity of pigmentation on the body and eye. (C) 96 hpf embryos after exposed to teratogen concentration exhibited morphological defects such as bending spine, pericardial edema, enlarged yolk sac and hatching delayed. (D) Coagulated eggs with organ malformation after exposure to toxic concentration.
