Fish developmental biology
WebThe embryonic development starts with the penetration of sperm in the egg. The process is called as impregnation. The sperm enters the egg through micropyle. In some fishes, the micropyle is funnel-shaped. As soon as sperm penetrates, there occurs a cortical reaction which prevents further entry of sperms. Even in those cases where polyspermy ...
