The fertilization envelope is a protective layer that forms around the egg after fertilization in many species, particularly in marine organisms like sea urchins and some amphibians. It is created by the exocytosis of cortical granules in the egg, which release substances that modify the egg's outer layer, preventing additional sperm from entering. This process helps ensure proper fertilization and contributes to the early development of the embryo by providing a stable environment. The fertilization envelope also plays a role in species-specific fertilization, ensuring that only sperm from the same species can successfully fertilize the egg.
