| Abstract: | The embryonic development of Odontobutis potamophila was studied in the present paper.The progress of embryonic development was observed under light microscope and figures were taken once an hour.The results demonstrated that the progress of embryogenesis,which had been lasting for 502 h since fertilization,could be divided into 8 periods including 33 stages.According to the number and size of blastomeres,formation and epiboly extent of the blastoderm,development of the central nervous system,the numbers an... |
