Anabarilius grahami is a cyprinoid fish endemic to Fuxian Lake, Yunnan, China. In this study, a comprehensive staging series of A. grahami was produced. The embryonic development of A. grahami was divided into six main periods: zygote period, cleavage period, blastula period, gastrula period, segmentation period and hatching period. Its embryonic development is essentially similar to that of zebrafish Danio rerio but relatively slower. The expression patterns of A. grahami sox2 , pax6a , six3a and rx2 genes were also cloned and checked during eye development. The four genes showed similar expression patterns to their D. rerio homologues, suggesting the evolutionary conservation of the regulatory network of eye development.
