Effects of PAHs exposure on sensitive F. heteroclitus embryo’s morphological development at stage 31. Representative photos show embryos with a normal development as well as b mild, c moderate, and d severe-to-extreme deformities. CD, cranial distance; EY, eye; HM, hemorrhage; HR, heart; PE, pericardial edema; PG, pigment; TB, tail bleed; TH, tube heart; YS, yolk sac. e Embryo deformity is significantly more severe in higher concentrations of Elizabeth River sediment extracts (n = 20 per exposure condition). Deformity of each individual embryo was scored based on the protocol specified in the Methods. ****p < 0.0001
