Synopsis
Stickleback eggs undergo rapid development shortly after fertilization in this educational film from 1925. The process begins with the germinal disc dividing into two blastomeres, followed by further divisions and muscular contractions. Title cards in French provide guidance on key observations. As development progresses, blood circulation initiates with the formation of red blood cells and arteries, culminating in the hatching of the egg. The film offers a detailed view of embryonic growth and physiological changes in the stickleback species.
