Abstract We describe a series of stages for development of the embryo of the zebrafish, Danio (Brachydanio) rerio . We define seven broad periods of embryogenesis—the zygote, cleavage, blastula, gastrula, segmentation, pharyngula, and hatching periods. These divisions highlight the changing spectrum of major developmental processes that occur during the first 3 days after fertilization, and we rev...
